Best Plants for Hydroponics: What Can You Grow?

October 1, 2026

If you’re wondering what you can grow hydroponically, the answer goes well beyond lettuce. Herbs, tomatoes, peppers, cucumbers, strawberries and plenty of other crops can grow without soil. Yes, even melons—but let’s talk about those vines before you invite them into the living room.

🌱 The short answer: Leafy greens and herbs are some of the easiest plants for beginners. Fruiting crops can be productive too, but often need more light, space, support and attention to pollination.

We’ve grown all kinds of crops in our Tower Gardens over the years. One lesson keeps coming up: choosing the right plant for your setup makes growing much easier. A tiny seedling doesn’t tell you much about how much room it will claim later!

This guide helps you choose what to grow. Once you have a few crops in mind, visit our Hydroponic Crop Library for individual growing guides.

What Are the Best Plants for Hydroponics?

For most beginners, lettuce, leafy greens and a few culinary herbs are a practical starting point. You can harvest their leaves without waiting for flowers and fruit, and many are easier to fit into a home growing system.

That doesn’t mean you have to stop there. Tomatoes, peppers, cucumbers, eggplant, strawberries, beans and peas can also grow well hydroponically when the setup meets their needs.

The best choice depends on the system you’re using. A crop that works beautifully in a large greenhouse hydroponic setup may be much harder to manage in a small indoor tower.

For regular salads: start with lettuce, arugula and other greens you enjoy.
For fresh flavor: choose herbs you already use in the kitchen.
For fruiting crops: plan for suitable light, mature plant size and any support or pollination needs.
For a Tower Garden: consider how each plant will fit alongside its neighbors as it grows.

You don’t need to grow the most adventurous crop on the list. Growing something you’ll actually eat is a much better goal.

Leafy Greens: An Easy Place to Start

Leafy greens are some of our favorite hydroponic crops. Many grow quickly, and you can often pick outer leaves while leaving the growing center to produce more.

Good choices include:

Loose-leaf, romaine and butterhead lettuce
Arugula
Kale
Swiss chard
Mustard greens
Broccoli rabe
Baby greens

Lettuce is particularly useful for learning your system. It doesn’t need pollination or a trellis, and there are plenty of varieties to suit different tastes and growing conditions.

Temperature still matters. Spinach generally needs cooler conditions and can be trickier to germinate, while crops such as Swiss chard and some kale varieties can handle warmer weather. Heat-tolerant lettuce varieties can also help extend your growing season.

🥬 Think beyond whole heads: If you prefer smaller, regular harvests, choose greens suited to picking a few leaves at a time. If you want whole heads, keep replacement seedlings ready for the spaces you’ll empty.

Herbs That Grow Well Hydroponically

There’s something satisfying about snipping herbs for dinner instead of buying a packet, using three leaves and discovering the rest looking miserable in the fridge a week later.

Many culinary herbs grow well in hydroponic and aeroponic systems, including:

Basil
Parsley
Cilantro
Dill
Chives
Mint
Oregano
Thyme
Sage

Match the herb to your conditions. Basil enjoys warmth, while cilantro generally does better in cooler weather. Woody herbs such as thyme and sage may establish more slowly than fast-growing basil.

Herbs also need room. A mature basil, dill or mint plant can become much larger than the little seedling you started with. Regular harvesting helps keep many herbs manageable and useful.

For crop-specific help, explore the herb section of our Crop Library, read our Cilantro Growing Guide or learn about growing sage hydroponically.

Can You Grow Tomatoes Hydroponically?

Absolutely. Tomatoes can grow very well hydroponically, but variety selection makes a huge difference.

A micro-dwarf tomato and a full-size indeterminate tomato may both begin as small seedlings. A few months later, one can be a compact plant and the other can be making a serious attempt to take over your growing area.

Micro-dwarf and compact varieties: useful for indoor gardens and smaller spaces.
Larger bush varieties: need more room and may need support.
Indeterminate varieties: can produce long vines and require substantial support and ongoing management.

Tomatoes need enough light to flower and fruit, suitable temperatures and successful pollination. Indoors, you may need to help pollen move within the flowers.

For detailed advice, read our Tower Garden Tomato Growing Guide. For smaller varieties, explore Best Compact Plants for Indoor Tower Gardens.

Can You Grow Peppers Hydroponically?

Yes! Sweet peppers, snack peppers and hot peppers can all be good hydroponic crops.

They need warmth and plenty of light to produce well. Some varieties stay relatively compact, while others become tall, bushy plants that need room and support as the fruit develops.

For indoor growing, compact varieties are often easier to keep close to the lights without shading everything around them. Choose peppers you’ll enjoy eating, too—a tower full of hot peppers is quite a commitment if nobody in the house likes spicy food.

Read our Pepper Growing Guide for variety selection, pollination, support and harvesting advice.

Can You Grow Cucumbers Hydroponically?

Yes, and a happy cucumber plant can grow fast. Planning for the vine before it gets big makes life much easier.

Traditional vining cucumbers need somewhere to climb and enough room for their leaves. Compact varieties can be a better fit for smaller spaces and indoor growing.

Pollination is another important choice. Some cucumber varieties need pollination to develop fruit. Parthenocarpic varieties can produce fruit without pollination, making them particularly useful indoors.

Compact and parthenocarpic describe different traits: one concerns plant size, the other concerns fruit development. Check both when choosing your variety.

Our Cucumber Growing Guide covers the details. For a compact option that can fruit without pollination, read about Quick Snack cucumbers.

Other Fruiting Crops You Can Grow Hydroponically

Tomatoes, peppers and cucumbers get plenty of attention, but they aren’t the whole menu.

Eggplant

Eggplant enjoys warmth and strong light. Compact varieties can be easier to manage in a Tower Garden, especially indoors. Larger plants and heavier fruit may need support.

See our Eggplant Growing Guide.

Beans and Peas

Bush beans offer a more compact option than climbing beans. Pole beans need climbing support, while peas generally prefer cooler growing conditions and often benefit from something to climb.

Learn more in our Bean Growing Guide, and find peas in the Crop Library.

Squash and Zucchini

Squash and zucchini can grow hydroponically, but their large leaves can claim a lot of space and shade neighboring plants. Plan for their mature size and check whether your variety needs pollination.

They can be rewarding crops when you have room. They’re less convenient when you’re trying to squeeze several large plants into one small growing area.

Melons

Yes, melons can grow without soil too. They need suitable warmth, light and space, and you may need to support both the vines and developing fruit.

For a first hydroponic garden, they’re more of a project than lettuce. If you enjoy a growing challenge, plan the space and support before planting.

Find squash, zucchini, peas and watermelon guides in the fruiting crop section of our Crop Library.

Can You Grow Strawberries Hydroponically?

Yes. Strawberries can work well in vertical hydroponic and aeroponic systems, with fruit hanging outside the tower rather than resting on soil.

They still need suitable light, temperature and variety selection to flower and produce well. Indoors, pollination may need your help.

Think of strawberries as a crop with its own needs, rather than an automatic upgrade from lettuce. Compact plants can make them appealing for small spaces, but compact doesn’t mean maintenance-free.

Find our Strawberry Growing Guide in the Hydroponic Crop Library.

What About Broccoli, Cauliflower, Cabbage and Celery?

These vegetables can also grow hydroponically. The important considerations are temperature, mature size and how you want to harvest them.

Broccoli: needs room for its leaves and suitable conditions to form a head.
Cauliflower: needs space and consistent conditions; it can be less forgiving than lettuce.
Cabbage: can develop large outer leaves, so allow room around the plant.
Celery: can become surprisingly large, but offers the option of harvesting outer stalks while the center continues growing.

Broccoli, cauliflower and cabbage are generally cool-season choices. Variety and local conditions matter, so choose them for the weather you’ll be growing in.

Explore their individual guides in the Other Vegetables section of the Crop Library.

What Are the Best Hydroponic Plants to Grow Indoors?

Indoors, start with your lighting and available space. The question isn’t just whether a plant can grow hydroponically—it’s whether you can keep its mature growth within the useful reach of your lights.

Some practical choices include:

Lettuce and baby greens
Arugula and other leafy greens suited to your indoor temperature
Herbs you can harvest regularly
Compact tomatoes and peppers
Compact cucumbers, preferably parthenocarpic when pollination is difficult
Compact eggplant, with suitable lighting

Leafy greens and herbs are usually the simplest starting point. Fruiting crops can grow indoors too, but generally ask more of your lighting, space and care routine.

For specific varieties, read Best Compact Plants for Indoor Tower Gardens. Our Light Guide explains how to give those plants suitable light.

Are There Plants That Aren’t Suitable for Hydroponics?

It’s important to distinguish hydroponics in general from the particular system sitting on your patio.

Root crops such as carrots and potatoes can be grown using specialized soilless methods, but they aren’t practical choices for standard Tower Garden growing ports. Large trees, sprawling plants and crops needing lots of underground space also require very different setups.

Even a suitable crop can be an awkward choice if it occupies too much room, shades neighboring plants or needs more support than you can provide.

🥕 Before planting, ask: Is this a good use of my growing space? A plant you technically can grow isn’t always the plant you’ll most enjoy growing.

How to Choose the Right Plants for Your Hydroponic Garden

Before filling your system, work through these questions:

What will you actually eat? Start with crops that already belong in your meals.
How much light can you provide? Match the crop to your sunlight or grow lights.
What temperatures will it experience? Choose for your season and growing location.
How large will it become? Leave room for mature leaves, roots and vines.
Will it need support or help with pollination? Plan for those jobs before planting.
How do you want to harvest? Repeated leaf picking, whole heads and fruiting crops offer different harvest patterns.

Think about neighboring plants too. Mixing crops works best when they have compatible growing needs and enough room to share the system without competing heavily for light.

If you’re still choosing a Tower Garden, our three-question buying guide can help you think through your setup. The FLEX vs HOME comparison covers the model differences.

Do These Plants Grow Aeroponically Too?

Many do. Hydroponics is the broader category of growing without soil using a nutrient solution. In aeroponic systems, roots hang largely in air and receive water and nutrients directly.

Tower Garden uses aeroponic technology, and many of the crops discussed here can grow in it. Their basic needs for light, suitable temperatures, space and plant care still apply.

For more background, read Aeroponics 101 or What Is Tower Garden?.

What Should You Grow First?

Start with a few crops you’re excited to eat. Lettuce, another leafy green and a couple of herbs make a sensible first planting, provided they suit your conditions.

You don’t need to fill every port on day one. Give yourself room to learn the routine, see how the plants develop and decide what you’d like more of.

Once you’re comfortable with water, nutrients, pH and lighting, add fruiting crops if that’s what you want to grow. There’s no gardening rule that says you must graduate to tomatoes, though. A tower full of salad and kitchen herbs can be exactly the right garden.

You can start your own seeds or begin with live seedlings. Our Seeds & Seedlings Guide explains both options.
