Top 10 Hydroponic Fruits & Vegetables to Grow and their Health Benefits

Hydroponics is a method of growing plants, in water, without soil. Minerals and nutrients are added to the water at optimum levels so the plants can devote its energy into producing fruits and vegetables and results in a larger yield.

Using hydroponics you can grow just about anything. Here’s our top ten fruits & vegetables to grow in a hydroponic greenhouse:


Vining plants such as tomatoes are ideal for indoor gardens as they require a small amount of ground space and you’ll have room to train them up to the ceiling. Being able to watch and control the nutrients the plant received enables the grower to enjoy a continuous harvest all year long without sacrificing taste. Tomatoes are a rich source of vitamins A, C and folic acid. They contain strong antioxidants that help protect against the risk of heart disease, diabetes and cancer.


Lettuce is a top choice for hydroponic gardeners as it requires little space, little attention and you can harvest leaves as it grows. You’ll get your first harvest in a matter of weeks when you can enjoy the rewards of your first crispy crop. Lettuce is a very low calorie veg that contains phyto-nutrients that possess health promoting and disease preventing properties. Rich in vitamins A, C and K and contains minerals such as iron, calcium magnesium and potassium which are essential for body metabolism.


Water loving fruits make a good choice for your hydroponic garden. Given enough space and support cucumbers will grow abundantly. Cucumbers are rich in micro-elements iron, sodium, potassium, magnesium, calcium and zinc. They also contain vitamins B, C and folic acid. These elements make cucumbers effective at cleaning the body from cholesterol, slowing down the process of ageing and regulating metabolism.

Spring onions

Spring onions are, in fact, very young onions harvested before the bulb gets gets to swell and grow. One pot can sprout dozens of onions and be harvested every 3 or 4 weeks! The antioxidants in spring onions help in preventing damage to DNA and cellular tissue by inhibiting the action of free radicals. Spring onions are loaded with vitamins C and K which are both essential for healthy bones. Spring onions natural properties are most commonly used to treat viral infections such as flu and colds. They also contain vitamins B and A.


Peppers will grow in very similar conditions to tomatoes, however raising night time temperatures and decreasing daytime temperatures improves fruit production after plants reach their mature height. Peppers not only add flavour and spice to your food but are low in calories and high in vitamins and nutrients. Full of vitamins A and C and a great source of fibre, folic acid and potassium give them great health and disease fighting properties.


Just like lettuce other leafy vegetables like spinach grow well in hydroponic systems. Spinach is fast growing and prolific if you keep it harvested. Spinach is an incredibly healthy green leafy vegetable well known for its antioxidant properties. It provides protein, iron, vitamins and minerals. Spinach is an excellent source of vitamins A, C, K, E, magnesium, folic acid, copper, zinc and many more making one of the healthiest green leafed vegetables going. It protects the heart, lowers cholesterol, helps with digestion, reduces ageing and provides a rich source of iron.


Strawberries thrive in wet conditions and grow well in hydroponic conditions. Providing bigger fruits than in soil and can provide harvest all year round. Strawberries are high in antioxidants and vitamin c which are well known immunity boosters. They also aid in lowering cholesterol and high blood pressure.


Blueberries require high acidic soil conditions and therefore grow better in hydroponic conditions. Controlling the ph content and nutrients are much easier and will make for a much bigger, healthier crop. Blueberries are well known for being high in antioxidants that protect the brain and nervous system. They are ranked one of the highest fruits for providing antioxidants and vitamins needed for a healthy body.


Herbs are a very popular choice as require little care and can produce an impressive crop. Not only do herbs provide taste and fragrance but they have a wide variety of health uses. Research shows basil helps reduce inflammation and swelling, it is high in antioxidants and helps protect against free radicals that cause ageing.


Coriander is a great herb to grow that only takes around 4 weeks and can produce 2-3 harvests. It requires no special requirements and while plenty of light will give you the heaviest harvest. Coriander has multiple health benefits. It contains vitamin c, vitamin k and protein and is a source of magnesium, iron and fibre. It is know to help with skin inflammation, high cholesterol, mouth ulcers, digestion and many other ailments.

10 Best (Easiest) Plants to Grow Hydroponically Indoors

Are you wondering what plants you can grow hydroponically indoors if you don’t have much space? Hydroponics, or the method of growing plants in nutrient-rich water rather than soil, can be used to grow a wide range of vegetables, herbs and other plants, but some plants are better suited for this soil-free growing method than others. Below, we take a look at 10 nutritious vegetables, herbs and fruit plants that are among the easiest plants to grow hydroponically at home. These plants will also adapt to aquaponics, an advanced hydroponic growing method that combines aquaculture (raising aquatic animals such as fish) with conventional hydroponics. While the small aquaponic herb growing kits available for consumers won’t allow you to raise fish for food, they do have the advantage of fertilizing your plants with the natural waste the fish produce in the tank below the grow tray.

1. Spinach

The health benefits of spinach make this leafy green vegetable a great addition to almost any healthy diet, but the unassuming spinach is also right there on top of the list of the best plants you can grow hydroponically at home. Not only does spinach grow well in most water-based gardens. You can harvest your hydroponically-grown spinach all at once, or snip off a bit at a time. The young leaves of the spinach plant make a particularly versatile ingredient as they can be eaten both raw and cooked (see different ways to use baby spinach).

2. Lettuce

Lettuce may well be the most popular choice among budding hydroponic gardeners. It is easy to grow, and you can keep harvesting the outer leaves as the plant grows and thereby benefit from a continuous supply of fresh lettuce. Don’t know which variety to pick? Try the extra healthy Romaine, or any other common leafy type, such as the Bibb.

3. Watercress

As the name implies, watercress is a water-loving plant that makes an ideal candidate for your hydroponic or aquaponic garden. It is also a great vegetable to grow at home as it doesn’t store well when cut, which means the watercress you find in the grocery stores is often already wilted. This semi-aquatic plant thrives best in water that is slightly alkaline and that keeps moving.

4. Cherry Tomatoes

Cherry tomatoes are one of the easiest non-leafy vegetables to grow indoors at home, and they also do well in hydroponic systems. Keep in mind, though, that tomatoes, including cherry tomatoes, require a lot of light to grow, so you might want to get a standalone grow light, or one of the cherry tomato growing kits with LED grow lights.

5. Cucumbers

The cucumber plant is another example of a food-producing plant that grows well in a hydroponic or aquaponic setting, provided that it gets enough sunlight or artificial light designed to boost plant grown. When planting cucumber vines, keep in mind that as the plants grow, the vines will likely need to be supported with a large trellis or wire cage. No room for vines and a large trellis? Popular among container gardeners, the bush types are much smaller than the more common vine types, and you can buy bush cucumber seeds conveniently through Amazon here.

6. Peppers

Like tomatoes and cucumbers, peppers are relatively easy to grow indoors at home, provided that they get a lot of natural sunlight or that their growth is supported by grow lamps. They are also well-suited to hydroponic cultivation. If you’re planning on setting up your hydroponic garden in your home, rather than in a large green house, you might want to consider opting for chili peppers and other smaller pepper varieties that are better suited for small spaces than bell peppers.

7. Kale

In recent years, kale’s health benefits have received a lot of media attention, and cookbooks focused on kale recipes abound. However, fresh kale is still not as readily available as many other vegetables, and non-organically grown kale is often laden with pesticides. By growing your own kale using hydroponics or aquaponics, or simply using soil as the growing medium, you’ll have fresh kale readily available. Plus, if you’re growing your kale in a controlled hydroponic system indoors, you will likely need no pesticides as plant-destroying bugs living in soil or flying around outside will have trouble accessing the growing plants.

8. Strawberries

Imagine if you could have fresh, locally-grown strawberries indoors all year round! With a well-designed hydroponic system, year-round cultivation of strawberries becomes easy as pie. To get started, purchase a couple of strawberry starter runners from a garden supply store, and place them in a refrigerator for a few of months before planting them in your hydroponic indoor garden. Such cold stimulation helps jump-start the growing process, and your strawberry plants should start producing flowers right after planting.

9. Mint

Although it is usually grown on land, orange mint (also known as water mint) is actually a semi-aquatic plant that in nature grows best in shallow water on the sides of ponds and streams. Also peppermint, which is a hybrid cross between spearmint and orange mint, loves water. Therefore, it is not surprising that both orange mint and peppermint are among the best herbs to grow hydroponically or aquaponically, even if you have no prior experience in hydroponic gardening. AeroGarden sells hydroponic herb garden kits that are ideal for indoor use and that are perfect for growing herbs like mint, basil, parsley and cilantro at home.

10. Basil

Basil is another example of a herb that is easy to grow in a hydroponic system. The easiest way to get started with growing basil in a hydroponic system is to buy basil seedlings at a garden center and transplant the seedlings into the hydroponic container after carefully rinsing the soil off the roots.

Top 9 Hydroponic Flowers

Why Hydroponic Flowers?

Flower gardeners spend countless hours tilling and tending to the soil. This makes flower gardening appear hard work, and if it takes this much effort, then why would you consider growing plants in a hydroponic system?

There are in fact several benefits and advantages flower gardening in hydroponics has over soil growing.

Results come much faster, you can tailor your nutrients to each plant species, and you have no weeds, insects and less disease to contend with. This delivers an up to a fifty percent faster growth in flowers, and yields are much greater than compared to soil growth.

With this in mind, you can now grow flowers all year round, and which can be expensive to purchase when out of season. You can also have as many cut flower displays around your home as you wish.

Before an in-depth look at each flower, here are nine of the best flowers you can grow in your hydroponic system.

  • Peace lilies
  • Hoya
  • Snapdragons
  • Dahlias
  • Rex begonias
  • Carnations
  • Orchids
  • Petunia
  • Zinnia

Peace Lilies

As an indoor plant, the Peace Lily can be one of the easiest to care for. You need the right growing conditions though. These tropical flowers are part of the Spathiphyllum family and are recognizable by their dark green leaves and white flowers.

While we can grow these in a hydroponic system, they don’t like to be over-watered. They can in fact be more tolerant to under watering than being around too much water. Peace Lilies, which grow in a hydroponic system, are often adapted versions where they send out small roots to absorb water. Here you can see Peace Lilies grown in small aquariums.

Many growers often wait until leaves show signs of wilting before watering, this can prevent over watering. If they are over watered, it can lead to root rot, and the plant will suffocate.

Tips for Growing Peace Lilies Hydroponically:

  • Peace lilies like a temperature range of 68 F to 80 F. This will deliver optimal growth.
  • Clean leaves and you can reduce the risk of pests. The most common being aphids and mealybugs.
  • Be sure to keep your lilies in warm draught free areas
  • The ideal pH range would be from 5.6 to 6.5.

Fun Facts about Peace Lilies

  • Despite the name, peace lilies aren’t related to true lilies.
  • NASA studied Peace Lilies because of their air-purifying abilities. They show them to be effective at removing formaldehyde, carbon monoxide and benzene from the air.
  • All parts of the Peace Lily plant can be poisonous as they contain calcium oxalate. If ingested in sufficient quantities, this can cause respiratory and stomach irritation. You should keep away children and pets from Peace Lilies.
  • Indoor varieties can grow up to around 16-inches while outdoor types can grow up to six feet in height.


Hoya plants are better known as the wax plant. These are a vine, shrub, and evergreen perennial creeper. When flowering, they adorn some gorgeous star-shaped flowers with leaves that can either be smooth or feel like soft felt. Hoyas are very low maintenance, which is one reason they are so popular for a houseplant.

Hoyas are another plant that doesn’t take to over-watering. Depending on the growing conditions, Hoyas can have flowers 1/4 inch in diameter up to 4” in diameter. There are many different Hoya’s choosing from, 200 species to be exact, and they all boast their own unique colors and shapes. So choosing the hoya, you desire is half the battle to growing and nurturing them.

Tips for Growing Hoya Hydroponically:

  • When pruning, avoid cutting the long tendrils, these are where flowers develop.
  • Hoyas require adequate drainage so they are not accidently over watered.
  • Likewise, this tropical plant can absorb moisture through the air, which is what makes it so low maintenance. Consider a system that uses humidity.
  • Hoyas prefer bright indirect light. What they don’t like are dark corners or direct sun. Hoyas can handle cooler weather from 50 degrees F up to warm temperatures of 77 F.
  • Maintain a pH range of 5.0-6.5

Fun Facts about Hoya

  • Even though there are over 200 different variations of hoya, you won’t find blue, purple, or violet colors represented.
  • Some species of Hoya have a Crassulacean Acid Metabolism
  • Each cluster of flowers on this plant can contain up to 40 individual flowers.


The botanical name for Snapdragons is Antirrhinum and means ‘like a snout.’ This plant is native around Europe and North America. They have become a popular favorite because of their vibrant hues, and their flowers that resemble a dragon-like mouth when pressed.

Mature Snapdragons can grow from 6 inches up to 48 inches depending on the variety, and the growing conditions. This means you may require some support for your plant, and the growing medium will need to hold them firm. Perlite is often the more common.

Even when grown in a soil-based medium, it’s common to grow flowers like snapdragons indoors before transferring them. This is because they are very sensitive to weather conditions. There are over 18 different snapdragons, and all these deliver bloom colors of pink, yellow, red, white, purple, peach, orange, and bi-colored.

Tips for Growing Snapdragons Hydroponically:

  • Snapdragons need adequate watering but not standing in moist conditions. Your growing medium will need to dry between cycles.
  • Snapdragons are perennials that require full sun with only occasional shade.
  • They prefer pH levels between 6.2 and 7.0.

Fun Facts about Snapdragons

  • Often called Dog’s Mouth, Lion’s mouth, Dragon flower and more depending where you are.
  • The leaves and flowers have some anti-inflammatory abilities.
  • We can apply them as poultices for ulcers or tumors
  • When snapdragons are mixed with tea, they can help detoxify the blood and increase urine production to clear the body from waste.


Dahlias are closely related to sunflowers, daisies, zinnia, and chrysanthemums. We know dahlias as octoploids, which means they have eight sets of homologous chromosomes.

If you grow these in your hydroponic system, you will need to be sure they have lots of space. As you are planting in a container, this does need to be at least 12 inches deep. Some varieties require deeper which can rule these out of your system. Dahlias grow half as wide as they do tall; so lateral space is important.

Dahlias like to have lots of light, and they are thirsty feeders. Your growing medium should dry out between watering schedules, and you will need to monitor your tank levels. Once planted, you will need to fertilize with a 10-10-10 NPK mix.

Tips for Growing Dahlias Hydroponically:

  • Dahlias need constant light to bloom and grow. It’s recommended that they receive a minimum of eight hours daily.
  • Dahlias are spring-planted flowers. This means they prefer warmer temperatures. Stick to a minimum of 60-degree temperatures and a maximum of 72 degrees.
  • If you prefer your dahlia’s being shorter and bushier, cut the center shoot above the third set of leaves to encourage shorter growth
  • Dahlias need a pH level range of 6.5-7.5.

Fun Facts about Dahlias

  • There are over 20,000 cultivars of Dahlia.
  • It’s the official flower of Seattle, WA although they are not native to the area.
  • Dahlias were known as a vegetable in the 18th century but later became more known as flowers.
  • They named them after 18th-century botanist, Anders Dhal.

Rex Begonias

Rex Begonias are unique in every sense. We do not know them for their flowers, rather their leaves and foliage. This is colorful and can be overlaid onto the thick fibrous leaves. It is possible to find a myriad of color options from maroon, lavender, gray, silver, pink and reds.

Rex Begonias were first noted in 1856 when a shipment of orchids to England included the mysterious plant that no one could identify. This plant is tropical and native to South America, Africa, and Southeastern Asia. There are over 1,831 species of begonia, each with their own intricate and original leaf appearance.

Tips for Growing Rex Begonias Hydroponically:

  • Since Rex Begonias are tropical and subtropical plants, they are native to jungle types of environments. It is this, which makes them great as houseplants as they require little light and prefer shaded and cool areas.
  • These plants can grow from 12 inches to 24 inches in height. With leaves growing an average of 4-5 inches, it is also crucial to be wary of outward growing space requirements.
  • You can tell when the Rex begonia has received too much light, as the foliage will turn brown.
  • Stick to temperatures between 60 and 85 F.
  • Maintain a pH range of about 5.7 to 6.2 for optimal growth.
  • Rex Begonias like humid conditions; this may mean misting their leaves early in the day.

Fun Facts about Rex Begonias

  • You can propagate Begonias by using stem cuttings.
  • The Begonia stem is actually designed to store water so that during dry periods of the year, the Begonia remains hydrated.
  • Begonias only have a life span of about 2 to 3 years on average. They can live a few years longer if they live in an excellent and nurturing environment.
  • The juice of the begonia plant is thought to relieve headaches and as an eyewash for conjunctivitis.


Carnations are by far one of the most popular flowers to be grown in hydroponic systems. They are also one of the most commercially grown flowers because of the number of individuals who have them as indoor decorations.

Carnation petals have a fantastic aroma and make any room feel inviting when they have a presence. On top of this, the leaves can also be edible and are sweet to the taste. Growing from cuttings is often the preferred method. If propagating in soil, it can take between two and three weeks when from seeds. Hydroponics can speed up this process.

Tips for Growing Carnations Hydroponically:

  • Make sure carnations receive 5-8 hours of uninterrupted sunlight daily.
  • Carnations will thrive the best with a pH level of around 6.0.
  • Rockwool starter plugs are ideal for seedlings up to 4 to 5 inches in height, at this stage, we can transplant them.
  • Keep the temperature range of 65 to 75 F.
  • Ebb and Flow, Dutch bucket or DWC systems are best suited to Carnation growth. They will need support when they grow.

Fun Facts about Carnations

  • Carnations are believed to be native to the Mediterranean area. However, because of extensive cultivation over the last 2,000 years, no one knows for certain where their origins lie.
  • Annual carnations, border carnations, and perpetual flowering carnations are the most common types that are grown.
  • Greeks and Romans used carnations in garlands.
  • Carnations are a bisexual flower. This means they have both male and female reproductive structures that inhibit better growth and production.


For many people, Orchids are among the most beautiful flowers there are. Around the globe, they are a gardener’s favorite thanks to their woody-thick roots and colorful blooms. One thing many lovers of this plant are unaware of is, around the world, most of these are actually grown in hydroponics systems.

The reasons for this that where these Orchids grow in tropical climates, they latch themselves to tree bark or in between rocks. As the climate can be wet, it exposes them to sufficient watering from the rain. Once the rain stops, it exposes the roots to the air and can have plenty uptake of oxygen.

Add to this surrounding organic matter which rots, and they have a steady stream of nutrients. This is hydroponics in its purest form, and it is what makes growing Orchids in a proper system so easy and so rewarding.

Tips for Growing Orchids Hydroponically:

  • Use Hydroton pebbles or similar media that has sufficient drainage and allows maximum airflow to the root systems.
  • Maintain temperatures between 60 and 80 F. Orchids also need high humidity levels and air circulation.
  • A pH range between 5.5 and 6.5 is best for orchids.
  • Lighting can comprise a 400w high-pressure sodium or metal halide bulb. Orchids will use more water when under strong lights.
  • Once your orchids flower, you can then place them around your home on display.

Fun Facts about Orchids

  • The flowers on orchids can survive for up to 6 months.
  • Out of the millions of seeds that orchids produce, less than a hand full will develop into a plant.
  • Orchid seeds do not contain endosperm, which is what they need to provide nutrients during germination. Because of this, they require symbiosis with fungi to achieve germination. Germination of orchids can sometimes take up to 15 years.
  • They use orchids in the perfume, spice, and medicine industries.


These popular South American flowers can withstand hot climates. They are widespread around many gardens in borders and in pots. There is an almost endless range of colors available, which is one reason they are gardeners favorites.

Most Petunias you see for sale are hybrids and are developed for specific purposes. As they grow, they can reach anywhere from six inches to four feet in height and have a spread of up to three feet. This means you will require support and lots of spacing to avoid overcrowding.

Tips for Growing Petunias Hydroponically:

  • Petunias need at least 5 to 6 hours of full light to thrive at their best.
  • When fertilizing Petunias like a balanced mix of 8-8-8, 10-10-10 or 12-12-12.
  • In germination, your Petunias will prefer warmer temperatures, however, once they have germinated, move them from this warm area so they can grow in cooler areas. They prefer cooler temperatures between 57 and 65 degrees Fahrenheit.
  • Petunias like pH levels of 6.0 to 7.0.

Fun Facts about Petunias

  • Petunias are an annual plant, so a full life cycle takes one year.
  • Common Petunias are edible and have a sweet and spicy flavor
  • There are four groups, which all Petunias fall into. Grandiflora, Multiflora, Milliflora and Hedgiflora.
  • Petunia comes from the word “Petun” which means tobacco in Brazil. These two plants are related and can be crossbred.


Zinnia are easy to grow and are a part of the daisy family. Being native to Southwestern United States and South America, they like to grow in full sun. At least six hours of full sun or bright light are recommended to get the best of these colorful plants.

Once they grow, they can range between 4 and 40 inches in height. This means you will require some support and a growing medium that can support their root system.

Their large range of bright colors and ability to withstand hotter climates makes them popular for planting in many a garden environment. Zinnias will reseed themselves each year. When selecting from the many varieties for your hydroponic garden, you will be better off selecting the more compact varieties.

Tips for Growing Zinnia Hydroponically:

  • Keep the temperature range between 74 and 84 degrees Fahrenheit. They can grow in temperatures as low as 60 degrees Fahrenheit.
  • Zinnias like moist environments yet they don’t like to be over-watered because they can fall foul of root rot. It can cope with dry spells better than standing in water
  • Once flowers show, they can benefit from 5-5-5 fertilizer for larger blooms.
  • Zinnias prefer pH ranges between 5.5 and 7.5.
  • Zinnias like a lot of light, but they can do just well in environments that receive less than 6 hours of light minimum.
  • If you want bushier plants, you can pinch the growth tip of the plants when young. This creates shorter side branching plants.

Fun Facts about Zinnia

  • Zinnia leaves have a sandpaper-like texture to them.
  • They named them after the German botanist Johann Gottfried Zinn.
  • They can have a single, semi-double or even double layers of petals.
  • Removing dead or faded flower heads, you will see an increase in flower production. We call this dead-heading.
  • Butterflies love Zinnia’s, and you’ll find an abundance of them attracted to your garden if you plant them outdoors.

This can be done indoors or outdoors, but because of the ease, many folks choose to keep their setup indoors. This is not the case for growing outdoors as there are heat and cold weather to deal with. Some Hydroponic plants also have need of high light levels and some require lower light levels. A well planned out Hydroponic growing system sorted on paper is a must before going any further to see if it is all going to work.

Hydroponics gardening systems have some advantages over conventional soil gardening. If you like fast results choose hydroponics. Growing flowers in a hydroponic system give you complete have power over the nutrient release and pH balance, allowing precise delivery tailored to the needs of each hydroponic plants. Without the physical barricade of soil, plants don’t need to spend as much energy drawing nutrients into their roots. There are no issues of weeds, insects, or diseases in a self-contained hydroponics system. All of these benefits put into the fact that plants grow up too much faster in hydroponic culture compared to those growing in soil, and have a greater flower yield as well.

The hydroponic flowers list that is grown successfully in a hydroponics system is almost endless same as a hydroponic plant list. Growing hydroponic flowers, like any other plant, will depend on your space and all growing facilities you provide. Larger or taller flowers like rose bushes, or gladiolus will require more space to prevent overcrowding.

If you’re new to the technique of hydroponic gardening, you may consider a complete hydroponic setup as an introduction to soil-free flower culture. A hydroponic system is a self-contained growing unit that may consist of a growing container, a water reservoir, growing media, and a pump that recirculates the water with the hydroponic nutrients and of course flowering plants.

How to Get Beautiful Flowers in Your Garden using a Flowering Booster

If you are growing flowers in your hydroponic garden, chances are you just have a single goal in mind: bigger, heavier blooms. The bigger your flowers, the more valuable they are. When a flower grows in size, it is usually also deeper in color and stronger in fragrance which can also increase its value. By using a quality flower booster, you can achieve the results you truly desire.

Sadly, too many hydroponic growers don’t take the steps necessary to achieve this goal. If you treat your flowers during the flowering stage in the exact same way that you treat them during the vegetative stage, you simply will deprive yourself of the kind of flowers that you can achieve.

The trick is to make the proper adjustments during the flowering stage of development that will truly get you the most benefit from your garden. This includes using a good quality flowering booster and making a few other adjustments to help get those flowers growing fast. Here are some simple steps to help you in getting bigger buds & flowers.

Check Your Phosphorus to Potassium Ratio – Every gardener knows that phosphorus and potassium and essential elements to a truly successful harvest. These elements help speed up plant metabolism and cell division which lead inevitably to the kind of heavy, large flowers that make gardeners envious. But do you know the correct ratio of phosphorus to potassium?

Conventional wisdom says that it should be approximately one to one, which is why one of the most popular flowering boosters sold is PK 14/15. Unfortunately, in this case, conventional wisdom has it dead wrong.

A flowering booster with this much phosphorus puts you at risk for phosphorus excess, which can create decencies in other essential nutrients. In reality, the best, most effective flowering boosters contain much more potassium and a lot less phosphors, usually at a ratio of two to one, such as PK 9/18. This combo can give your plants the essential boost of nutrients that it needs to really grow to its potential during the flowering stage.

Switch to a 12/12 Photoperiod – Most hydroponic growers stick to a to a photoperiod where they have their lights on for eighteen hours and off for six hours. While its true that light is essential for growing success, no matter what the stage, you actually want to cut back on the light during the flowering stage. By keeping the lights on twelve hours a day in instead of eighteen during the flowering stage, you will not only improve the performance of your plants, but you will also be saving a bit of money.

Use Red Spectrum Light Only – During the flowering stage is when your plants are going to gain the most benefit from bulbs that provide red spectrum light, such as high-pressure sodium. You might also consider using red-only LED lights. These are a bit pricier, but they have the advantage of having a very low heat output.

After you have all of these elements in your hydroponic system optimized, educate yourself on other hydroponic nutrients and flowering boosters that you can use to create those truly huge flowers.

The 5 Best Plants for Hydroponic Systems

Congratulations! You’ve constructed your first hydroponic system and now you’re ready to start growing! But now the big question comes up: What should I grow in my hydroponic garden?

Chances are, you have big dreams of providing for your family at every meal from your bountiful set-up. That can happen, but we advise you to take it slow at first! If you go all out right away and run into complications, you may get frustrated and drop the whole project. You definitely don’t want that to happen, so it’s important to run through a few test crops first. Once you get a handle on the system, you will be ready to expand and diversify your hydroponic garden.

Top 5 Plants for New Hydroponic Gardens

The five best plants to grow in a hydroponic system are:

  1. Lettuce
  2. Spinach
  3. Strawberries
  4. Bell Peppers
  5. Herbs

Growers have found that these plants take to hydroponics like a duck to water. They’re durable, fast growing and don’t take a lot of work to get started – all great features that give a new grower a little wiggle room!

Now let’s look at each of these a little closer:

Lettuce in Hydroponics

Lettuce (and most other leafy greens) should be your first plant to try with a hydroponic system. These plants have a shallow root system that matches their short above-ground height. That means there’s no need to tie stakes or set guides for the plant. Instead, you just let them grow while regularly changing their nutrient solution. Eventually, they will look good enough to eat, and you can!

  • Grow time: About 30 days
  • Best pH: 6.0 to 7.0
  • Tip: Stagger plantings so you have a continuous supply of lunchtime lettuce!
  • Variety options: Romaine, Boston, Iceberg, Buttercrunch, Bibb

Spinach in Hydroponics

Spinach grows quickly in a hydroponic system, particularly when using the Nutrient Film Technique or other methods that keep the nutrient solution highly oxygenated. You’ll also use far less water than an in-the-ground garden. It’s easy to start these plants from seed and a week after sprouting, move them into your system.

  • Grow time: About 40 days
  • Best pH: 6.0 to 7.5
  • Tip: For sweeter spinach, keep your grow temperatures between 65 degrees F and 72 degrees F. The lower temperatures may slow grow time, though.
  • Variety options: Savoy, Bloomsdale, Smooth Leafed, Regiment, Catalina, Tyee, Red Cardinal

Strawberries in Hydroponics

The worst thing about strawberries is how seasonal they are. If you don’t get them locally when the crop is ready, you’re relying on trucked-in berries that begin deteriorating as soon as they’re picked. With hydroponics, you can have a ready-to-eat crop of strawberries all year long. Harvesting is super-convenient as well – no bending over! Strawberries seem to do best with an ebb and flow system, but deep water culture or nutrient film technique can do for a small crop.

  • Grow time: About 60 days
  • Best pH: 5.5 to 6.2
  • Tip: Don’t buy strawberry seeds, which won’t be berry-ready for years. Instead, you want to buy cold-stored runners that are already at that stage.
  • Variety options: Brighton, Chandler, Douglass, Red Gauntlet, Tioga

Bell Peppers in Hydroponics

Bell peppers are a slightly more advanced hydroponic plant. Don’t let them grow to their full height, instead, prune and pinch plants at about 8 inches to spur pepper growth. Deep water culture or ebb and flow systems are best for peppers.

  • Grow time: About 90 days
  • Best pH: 6.0 to 6.5
  • Tip: Plan to provide up to 18 hours of light for these plants each day, and raise your light rack as the plants grow, keeping plants about 6 inches from the lights.
  • Variety options: Ace, California Wonder, Vidi, Yolo Wonder

Herbs in Hydroponics

There are a wide variety of herbs that work wonderfully in hydroponic gardening. Studies have shown that hydroponic herbs are more flavorful and aromatic than those grown in the field. What herb do you want to grow? Basil, chives, cilantro, dill, mint, oregano, parsley, rosemary, thyme, and watercress are all great options. Herb production is another great way to test out your new hydroponic system, and nearly every system style is suitable for a round of herbs as you learn the ropes!

  • Grow time: Varies by plant
  • Best pH: Varies by plant
  • Tip: Flush your growing medium about once a week to get rid of any extra nutrients that your plants haven’t (or won’t) absorb.
  • Variety options: Name your favorite, and you’ll find instructions for growing it!

what are the best plants for a hydroponic garden

Even if you don’t consider yourself a gardener or don’t have an outside space for gardening, you can still enjoy the benefits of growing your own plants. There are many that can be grown indoors hydroponically, including herbs, vegetables, and house plants.

I have put together 25 plants that are easy to grow in water or hydroponically. Although many plants will root and grow well in just a glass jar and a little water, you can accelerate their growth with correct plant nutrition and adequate lighting and be harvesting faster than you would from an outside vegetable garden.

Most of these selections you will likely already know of, but you may not be aware that they can be grown without soil. If you’re ready, let’s get started.


Growing Herbs Hydroponically

Imagine being able to pick fresh herbs whenever you need them. That could change, not just the taste of your food, but also the nutrient content in the dishes you prepare. It’s also important to note that although you can plant from seeds in most cases, taking a cutting is almost always the preferred option. This method not only gets the plant growing stronger but faster as well.

Growing Vegetables Hydroponically

In addition to the above herbs, there are many more types of plants you can grow in a water-based growing medium, including various vegetables. Many are the same types you would grow in your outside garden, and others are a variety specifically developed to grow in a smaller space. Remember that as long as you are feeding your plant and giving it light, it will grow.

For support of larger plants like tomatoes, I prefer to use clay pebbles, as they allow the roots to have a firm hold on something. The below table shows just some of the vegetable plants you can grow hydroponically.

The Benefits of Growing Vegetables Hydroponically at Home

When you go to the grocery store, do you feel like you are forced to buy what they have? Of course, you could go to a farmers’ market and shop around at some of the specialty shops. But let’s be realistic, who has the time to do that? Especially if you have a family and a job, there just aren’t enough hours in the day to be as conscientious as we wish.

We all want to provide healthy good quality food for ourselves and our family. Every day there seems to be a new article either online or on the news about GMO foods or toxins in the water from farms. By growing it yourself, you know what you’re eating, and you know what has been used to nourish that plant you’re bringing to your table.

If you’re a traditional gardener, you may balk at the thought of growing plants in what some say is an artificial environment. I felt the same until I did some research.

It turns out hydroponically grown vegetables have an equal amount of vitamins as those grown in the ground. Of course, this is dependent on the quality of the nutrients you are putting in their growing water. However, the same can be said for soils. If you grow a plant in poor soil, it will be lacking in flavor—if it grows at all. The nutrition you receive from it will also be lessened. (Organically grown vegetables can also vary in vitamin content as well.)

Here’s a quick list of some of the benefits of growing plants hydroponically:

  • You know where your food came from.

  • You can avoid using any pesticides.

  • Hydroponic plants generally grow faster than those grown in soil.

  • The yields are often greater than those grown in soil.

  • You don’t need a garden space—or much space at all—to grow plants.

  • Hydroponic plants generally attract fewer pests and diseases.

  • There are no weeds to pull.

  • Hydroponic gardening saves water.

Where Does Your Food Come From?

Maybe the greatest benefit of growing your own food hydroponically is that you know exactly where it came from and how it was grown. Plus, you can be sure that no harmful pesticides were used.

Helpful Tips for Growing Plants Indoors Hydroponically

Here are a few additional tips and considerations to keep in mind for your new hydroponic garden:

  • Lighting: Just because a plant is grown in water doesn’t necessarily mean it doesn’t still need sunlight. Especially in the case of fruits and vegetables like tomatoes and most anything with flowers, you’ll need to either place your plants near a south-facing window or figure out some other way to get them much-needed light—ideally at least six hours a day. Unfortunately, this can be very complicated due to various spectrums of light, intensity, and power, not to mention the different needs of different plants.

  • pH Level: Depending on what you’re trying to grow, not having the optimum pH level of your water can greatly diminish your plants’ ability to absorb vitamins, carbohydrates, and other nutrients. (For instance, most of the herbs mentioned above thrive in a pH level that is lower than that of most tap water.) So it’s important to check the ideal pH preferences of your plants and adjust the water accordingly.

  • Climate/Temperature: As most plants prefer a temperature between 60–80°F, it’s important to keep an eye on how hot or cold it gets around your hydroponic garden. Sometimes you’ll need to protect it from the heat generated by your grow lamps or a nearby radiator. Other times you’ll need to protect them from falling temperatures in the winter, even though they’re indoors.

What is nutrient film technique (NFT)?

Nutrient film technique (NFT) is an active hydroponics system where water containing dissolved nutrients is pumped into a grow tray, so that those nutrients can be absorbed by plants as the water passes through their roots. That water is then drained into a lower reservoir to be eventually pumped back through the grow tray.

It is one of the most popular and versatile systems for hydroponics and can be particularly useful for fast-growing, lightweight plants like lettuce—though it is not as effective for growing heavier crops such as tomatoes. For more information, check out this helpful The Spruce article on Nutrient Film Technique Hydroponic Gardens.

What’s the Difference Between Hydroponics, Aquaculture, and Aquaponics?

It’s easy to get confused by the terminology, as there’s jargon specific to various cultivation techniques. There are also many people who use the words interchangeably, which further adds to the confusion. In fact, the term aquaculture includes water plants, so you can see how people are easily misled by the tangle of terminology.

Let’s clear up what we’re talking about to shed some light on the subject:

  • Hydroponics: This refers to growing plants in water that has minerals and nutrients added. For larger plants, often clay pebbles, coir, perlite, or gravel is used to support the roots. There is no soil.

  • Aquaculture: This is the raising of fish, crustaceans, mollusks, aquatic plants, and algae. Fish farming, which we have done on our farm, comes under this category.

  • Aquaponics: This combines the two areas of aquaculture and hydroponics, using fertile waste water from fish or other aquaculture activity to enrich the water for the plants. Often plants will be grown on top of a tank, aquarium, or lake, with fish swimming (and defecating) below.

A Video About Hydroponics

Below is a video about growing plants in a hydroponic system. The gentleman in the video uses Rockwool insulation to suspend the lettuce seedlings in the plastic basket in the water. Although this setup is larger than you may want, I’ve included it because you can see how quickly your plants will grow and how healthy they look.

The lighting for water system plants can vary. Some people use fluorescent bulbs, as the man in the video has. Others use LED lights or natural light. When using natural light, often the gardener will have their plants lined up vertically near their window. This is known as window farming or window gardening.

Some systems use a small air pump, the type used in an aquarium to keep the water moving and to keep the water aerated. You may find you don’t need one if you are adding water every couple of days along with your fertilizer.

Every outside gardener knows the heartache of tending to seedlings and then coming out in the morning to find something has eaten them in the night. It’s enough to make you throw in the trowel (see what I did there).

That is just one of the reasons I love indoor hydroponic gardening. No pests. Plus, I hate the waiting for things to grow. With this, you can almost see these grow overnight. The combination of the food in the water and the lights make growing conditions perfect.

No mulching, no digging, no weeding! Need I say more? If you ever wondered how the supermarket buys perfect-looking herbs and lettuces, this is the answer.

Why Not Give Hydroponics a Try?

I can think of no reason not to try using a hydroponic system, even if you use it in conjunction with your normal gardening. This means you can have fresh food when you want it, and the food miles work out to about 6 feet depending on the size of your kitchen. It sure beats having it flown in from a country thousands of miles away.

Kids will love seeing the plants growing in front of them. They may even be more receptive to eating their greens if they have helped grow them.

Hydroponic farming at home: How to grow safer, better and cheaper food in your HDB flat

by ValueChampion

Did you know you can farm in your HDB flat? Find out how hydroponic farming can help you grow better, safer and cheaper food at home!

Last week, 131 people in Singapore fell ill with gastroenteritis after consuming food from a catering service, which follows 2 other incidents where about 300 people suffered food poisoning from a restaurant and a different catering service. While eating bento boxes at a conference or going out to restaurants is unavoidable, these incidents to make us wonder if there is a safer way to eat.

In fact, there is a way that is not only safer, but also cheaper and better for the environment: hydroponic farming. Having become quite popular in the last few years, hydroponic farming is quite easy for consumers to replicate at the comfort of their homes because it only requires water. Without the need for soil, hydroponic farming eliminates the concerns for pests or messiness. Here, we discuss how Singaporeans can grow their own produce at home while also saving money.

How Much Does Hydroponic Farming at Home Cost?

Hydroponic farming equipments are relatively cheap to acquire, or even to build. A simple search for “hydroponic kits” on Lazada shows a variety of options that range from S$60 to S$160, depending on the size and functionality of the kit.

While pricier versions come with better designs and integrated lighting functionality, you can purchase or even build simpler versions like the one pictured above with just pipes, plastic baskets, a water pump, a tube and a source of light (i.e. lamp, window, etc.) for much less. All you really need is a system that circulates water and holes where you can “plant” something with help of a growth media like gravel or even cotton.

Hydroponic Kit Cost
Small Bigin Indoor Garden with Lamp S$58.53
8 planting site kit S$58.8
36 planting site kit S$83.3
72 plating site kit S$142.7

Once you have a working hydroponic kit, it’s very cheap to operate and grow your own produce at the comfort of your home. The ongoing costs of running your own farm should be about S$5 or less per month, which accounts for seeds, nutrients, electricity and water for 30-45 days it requires to grow most vegetables.

Potential Savings from Hydroponic Farming

To sum out the previous section, it costs about S$100 to set up a hydroponic kit and another S$5/month to operate it to grow around 36 produces every 45 days. If you were to do this for 1 year, the total cost is approximately S$160 for producing roughly 300 sets of vegetables and fruits. t o assess whether this is a financially good move, we can compare this cost to how much it could help consumers save on what they spend on groceries.

According to the government’s survey, an average household spends about S$1,334 per month on food and beverage. Even if growing your own veggies could reduce a family’s food budget by around 1%, the reduction in grocery bill can help pay for the whole system within the first year, with additional S$100 in savings in each of the subsequent years.

Other Benefits of Hydroponic Farming at Home

Hydroponic farming is ideal for apartment dwellers without much space due to their compact & vertical structure and the lack of need for soil. Besides the spatial and economic advantages, however, hydroponic farming also has many other benefits for consumers.

First, growing with hydroponics is known to greatly increase the rate of growth of plants, sometimes helping them mature to 25% faster and produce up to 30% more than the same plants grown in soil. Not only that, since it doesn’t require using fertilizers or pesticides, it tends to be much safer for the environment. Finally, your produces will also be much more delicious and fresher because you can wait to harvest them until they are fully ripe; commercially produced vegetables and fruits often have to be harvested early so that they can be transported to stores.

If you are interested in trying farming at your flat, leafy greens like lettuce, kale, spinach and small but “water friendly” root plants like radishes, onions, carrots and strawberries are the easiest to grow in a hydroponic garden.

Save Even More on Your Farming & Food Costs Through Credit Card Rewards

If you are looking to save even more on setting up your hydroponic farming, it’ll be a good idea to try and build your own. There are a lot of instructions and manuals available online, most of which can be completed with simple components you can easily purchase. Whether you decide to build your own or purchase one, using a credit card to make the purchase can help you rack up a lot of reward miles or rebates, especially since it will be a relatively big purchase.

There are many cards that can earn rebates on online shopping and even on utilities, so you can earn rewards on the initial set up and while operating your home water farm. Furthermore, some of these cards can also be used as grocery credit cards to reduce your food costs even further. For example, OCBC 365 Card and UOB One Card both provide rebates on online shopping, monthly bills and groceries.
