Hydroponic Crop Library: What to Grow & How to Grow It

Find the right plants for your Tower Garden, hydroponic or aeroponic system.

Wondering what you can grow in a Tower Garden, hydroponic system or aeroponic garden? You're in the right place.

We've grown everything from lettuce and basil to tomatoes, cucumbers, eggplant, squash and melons without soil. But different plants have very different needs, and choosing the right crop for your space can make growing a whole lot easier.

🌱 Start here: Browse by crop type, then look at where each crop grows best, the temperatures it prefers and whether you'll need to think about things like pollination or plant support.

You don't need to grow everything at once. Pick crops you actually like to eat, learn what they need and build from there.

Not sure what to plant first? Our Best Plants for Hydroponics guide helps you choose crops that suit your space, season and growing setup.

How Do You Choose What to Grow?

One of the most common questions we hear is simply, “What can I grow?”

The answer is a long list, but that doesn't necessarily help you decide what belongs in your garden.

Before choosing a crop, think about:

  • Your available light. Fruiting crops generally need more light than leafy greens and herbs.
  • Your growing temperature. Variety matters. Some crops and varieties handle heat much better than others.
  • Mature plant size. A full-size cucumber or tomato can take up considerably more room than basil or lettuce.
  • Pollination. If you're growing indoors, some fruiting crops may need your help.
  • Support. Vining and heavy fruiting plants may need cages, trellises or other support.
  • What you'll actually eat. Growing something just because you can isn't nearly as rewarding as regularly harvesting something your family loves.

Growing Hydroponic Crops Indoors

Growing indoors changes which varieties make the most sense.

You aren't just asking whether a tomato or cucumber will grow hydroponically. You also need to ask whether the mature plant will fit beneath your lights without shading everything around it.

Leafy greens and herbs are excellent choices for indoor systems. Fruiting crops can also grow very well indoors, but compact varieties are often easier to manage beneath grow lights.

If indoor growing is your goal, see our Best Compact Plants for Indoor Tower Gardens guide for tomatoes, peppers, cucumbers and other crops that are easier to manage in limited space.
