All right! So you've decided to try the exciting world of hydroponic gardening; I know you will love it. It really is quite a thrill to have a thriving indoor vegetable garden in your spare bedroom.
This page provides a little more detail on the proper crops to choose for your new garden.
Food for thought: Most of the root crops (potatoes, beets, carrots) can be bought cheaply in the store, and offer little advantage for hydro gardening.
Save your space for the faves: Green leafy crops like
lettuces, cabbage, chard, & spinach; and the fruits: eggplant,
pepper, tomatoes, beans and peas. Make the most of your indoor vegetable garden.
Try to find "greenhouse varieties" of vegetables for your indoor hydroponics gardens; they don't require pollination (see our Pollination Page for tips on that).
Below are some strains of veggies that are suitable for hydro, and a few growing tips for good measure.
Heirloom DiCicco Broccoli
Broccoli: I have grown the most beautiful broccoli heads in my hydro gardens. Granted, you won't get a huge crop, but steamed and topped with melted butter, it makes for a delightful taste treat. One plant per pot, as the leaves spread out pretty far. Broccoli prefers well-aerated growing medium and likes it cool, in the 60s. We look for:
Cabbage: One per pot, too, they get pretty big. You can let it head or harvest the outer leaves as it grows, like you would with lettuce. Below is an heirloom variety and also a new mini cabbage (picture) that should do well in Hydro. We've never tried that one, so let us know if you do:
Chinese Cabbage- Pak Choi hybrid
Chinese Cabbage/ Pak Choi: Easy to grow, excellent for authentic stirfry
Carrots: Have you ever tasted home grown carrots? Well then, you're in for a treat! Hydro carrots are sweet and tender. Grow the short varieties only, in vermiculite or perlite (light and well aerated); plant seeds on top of pot and keep moist; thin to about 1-1/2 inches apart. Carrots cannot be grown in LECA balls, for obvious reasons.
Try these varieties: Gourmet Short 'N Sweets, Thumbelina, Little Finger, Caracas (pic below):
Cauliflower: One per pot. Cauliflower apparently can be tricky, as it is sensitive to temp changes and prefers it cool. I have never tried to grow it, as I don't care for the taste of cauliflower. Good luck, let me know if you grow them successfully in your indoor vegetable garden.
Chard: Harvest like lettuce; keep it cool. Great cooked like spinach. Why not try this colorful variety:
Cucumbers: A great choice for hydro, I have had very good luck with cukes! They like high humidity and warm temps. Usually one vine is more than enough to keep you in salad cukes for the whole season.
Prune the vine to one
main stem, just like tomatoes, and train up a string. Fasten the plant
to the string with loose loops of garden wire. Pinch the ends off when
the plant reaches the end of the support string, up under the lights.
Remove the tendrils which sprout and wrap around everything in sight.
English cukes (greenhouse) do not require pollination and are seedless.
Hydroponics-friendly varieties: Burpee-Spacemaster (pictured), Johnnys-Diva, Sweet Success, Burpless

Heirloom Black Beauty
Eggplant: Black Beauty; pinch off a few flowers to get larger fruits; Eggplant likes it hot but not too hot; it can be tricky; I have had all the blossoms drop and not set. When you do get fruits, keep them picked right when they mature to spur additional produce.
Bush Green Beans
Green Beans: Are a great choice for an indoor vegetable garden. In winter, grow bush beans indoors; in summer, grow pole beans outdoors (patio). Pole varieties need to be trained up a string, and can be planted close together (6" apart). Beans prefer a looser aggregate, like coco and perlite, and good drainage. Try Burpee-Contender; but it's hard to beat the flavor and tenderness of Kentucky Wonder pole beans. Give 'em a try.
Seeds for your indoor vegetable garden:
This fascinating website offers a great selection of heirloom seeds, well packaged to last for years:
Peas: Hydroponic peas are both deliciously sweet and tender; try sugar snaps or snow peas for a tasty change of pace. Peas need cool temps; plant 3-4" apart and train them up a string or trellis. Pick the pods as soon as they are fully formed to spur continuous fruiting. Pictured below is a new compact strain that should do well in Hydro, Peas-In-A-Pot:
Peppers (bell & hot): Peppers are a great choice for hydroponics! Pick from green bells, yellow sweet banana or hot chili peppers, the variety is astounding. Pepper plants like it warm and require high light. Some strains require training up a string if they get too tall.
Hydroponics-friendly varieties: Delphin, Plutona, Tango, Luteus, Goldstar
Burpee puts out a nice mixed-seed collection of hot peppers, as shown below:
Cherry Belle Radish
Radishes: Grow in vermiculite or perlite, 2" apart; they need loose media, ample light and cool temps or they will bolt.
Try White Globe, Cherry Belle
Heirloom Bloomsdale Spinach
Spinach: A cool weather crop, plant 3-4" apart. Spinach is fast growing and prolific if you keep it harvested. Needs well-aerated medium with adequate drainage.
Squash & Zucchini: Squash takes a lot of space; train yellow squash up. Zucchini is a huge space hog, hardly worth it, but is a prolific producer.
