When you think of basil, your first thought might be of creamy pesto sauce.

This herb is also one of the most common crops for home hydroponic systems, because it’s forgiving for new gardeners and easy to grow in high quantities.

As long as it’s kept in warmer temperatures and receives frequent pruning, it will flourish in your hydroponic system.

2. Beans

Beans are fast growing, low maintenance and high yielding, so of course they’re perfect for hydroponic growing!

They also create nitrogen from the air, so they don’t need quite as many nutrients as some other plants.

Since space is typically a concern in hydroponics, stick to bushy varieties over viny ones, so you don’t need to add any vertical support.

3. Blueberries

This crop loves water, so they’re perfect for hydroponic growing.

Dwarf varieties of blueberries work best in hydroponic systems since they’re bred to be shorter.

You’ll just have to remember to pollinate your plants manually if you’re growing indoors.

4. Bok Choy

Also known as Chinese cabbage, Bok Choy loves water, and it’s fairly tolerant of other temperatures too.

This makes it a great addition to hydroponic systems that grow multiple types of crops.

Plus, you can harvest only a few leaves at a time to keep it growing or harvest the whole thing at once!

5. Borage

This medicinal herb is one of the easiest edible herbs you can grow.

It needs quite a bit of fertilizer when grown in the ground, but this isn’t a problem when growing hydroponically.

Plus, its colorful star shaped flowers are sure to add nice decoration to your system.

6. Cabbage

This global food staple is a fairly hands-off crop to grow hydroponically.

The only problem you’ll need to watch for is splitting, which is when the head breaks apart.

It also loves having a constant source of moisture, so it adapts well to hydroponic systems.

Plus, it prefers partial sun, so it does well under grow lights too!

10. Chervil

This delicate culinary herb is used frequently in French cuisine.

Chervil prefers indirect light and cooler temperatures, so it’s great for indoor hydroponic growing, especially in the summer.

It doesn’t transplant well, though, so try to plant it in the system as early as possible.

11. Chinese Evergreen

Chinese evergreens are one of the easiest houseplants to grow—they make even beginner growers look like experts!

Houseplants are great for both commercial and hobby indoor hydroponics, as they sell for quite a bit and don’t require too much light.

This makes it great for hydroponic growers with little time to spend on tasks like pruning.

14. Coleus

This tropical shrub can’t stand the cold, so it’s great for growing in indoor hydroponic systems if you live somewhere with freezing winters.

The more water coleus gets, the more vibrant its colorful leaves become.

So, growing it hydroponically is a great choice!

15. Cucumbers

Water-loving cucumbers are great vining plants for hydroponic greenhouses.

Greenhouse varieties of cucumbers are seedless and have thinner skin than field grown varieties.

Because they’re vining crops, you just have to be sure to include supports in your hydroponic system for proper growth.

16. Dahlias

Dahlias are a type of flower that grow well under grow lights.

These vibrant flowers come in many different varieties, with different heights, leaf colors, patterns and shapes!

They’re also easy to clone through propagation, so you can multiply your supply year after year.

17. Dill

Dill has a long history of cultivation, dating back five centuries!

It grows well indoors, you just need to provide ample light.

This herb grows a fragile taproot, a long anchoring root, so it’s best to plant it directly in your hydroponic system, if possible.

18. Fiddle-Leaf Fig

This houseplant has a reputation for being finicky, so it benefits from the special care of a hydroponic system.

Fiddle-leaf figs grow tall and need lots of light.

So, they work best for outdoor growing, or in rooms with lots of natural light.

19. Geranium

You can anchor the roots with a heavy growing medium at the bottom of the reservoir.

28. Mint

Mint is so resilient, it lives and thrives on every continent except Antarctica!

But others leave their orchid in the water 24/7, with weekly water changes to prevent bacteria growth.

30. Oregano

Since radishes are root crops, they’re a little more challenging to grow hydroponically than other crops.

But with the right nutrient solution, hydroponic radishes will turn out big and tasty.

Try to limit the nitrogen levels of your solution in order to promote root growth, rather than leaf growth.

36. Rex Begonia

Rex begonias are famous for their colorful and thick leaves.

These tropical plants require little light and prefer shaded, cool areas.

And even though they only live for two or three years, they’re easy to clone so you can keep bringing it back year after year.

They’re also considered one of the easiest houseplants to grow.

Give spider plants bright, indirect sunlight and monthly nutrients for best results.

42. Spinach

As a leafy green, spinach naturally flourishes in hydroponic settings.

And like lettuce, this popular crop does best in cooler temperatures.

In fact, spinach will actually have a bitter taste if it’s grown in too much heat!

43. Spring Onions

It’s easy to grow a lot of these small onions in a small space.

And since hydroponic systems famously save space, it’s the perfect match!

Just make sure you use a growing media with enough room for the onion bulb to grow.

44. Strawberries

Strawberries come in either the short-day or day-neutral types, and you’ll want to use day-neutral for your hydroponic farm.

This is because you can manipulate day-neutral strawberries into fruiting, which is triggered by being frozen.

To grow hydroponic strawberries, you need strong light, good airflow and a freezer for manually chilling the plants.

45. Thyme

Fresh thyme leaves have a short shelf life, so growing it for chefs is a smart choice.

Like many other leafy herbs, thyme thrives in hydroponic systems.

Plus, hydroponics gives you the ability to keep your thyme plant alive all year for constant access.

46. Tomatoes

Tomatoes have long been a favorite for greenhouse growers.

They come in bush and vining varieties, but since bush is harder to control, vining is better for indoor growing.

Usually, hydroponic growers use the Dutch bucket system with two plants per bucket to grow tomatoes.

47. Viola

These flowers like a lot of water, so they work well in hydroponic systems.

Flowers often grow best outdoors, but violas will do well inside too.

They require little maintenance, just cut off dead buds quickly and don’t allow seeds to form to keep them alive longer.

48. Watercress

As the name suggests, watercress loves water, and it even grows partially in running water in the wild.

It’s best known as a vegetable, but its flowers are edible too.

To get it to flower in a hydroponic system, you’ll need to switch to a flowering nutrient solution about halfway through it’s vegetative growth.

49. Watermelon

Watermelon loves water too. In fact, watermelons are 92% water!

The biggest challenge with growing it hydroponically is making sure your system can support the weight of your plant’s massive fruit.

Use both horizontal and vertical trellises for best results.

50. Zinnia

Zinnias are an easy flower to grow in any growing media!

For hydroponic systems, compact varieties, like profusion zinnias, will grow best.

They also cope with dry conditions better than standing water, so wick, or ebb and flow systems will work best.
