INDOOR VEGETABLE GARDEN
Which Crops Do Best In Hydro?
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.
for thought: Most of the root crops (potatoes, beets, carrots) can be
bought cheaply in the store, and offer little advantage for hydro
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.
Indoor Vegetable Garden Varieties
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.
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 Heirloom DiCicco Broccoli.
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. Try Early Jersey Wakefield Heirloom Cabbage or the new mini cabbage (picture below) that should do very well in Hydro. It is offered by Burpee and is named Caraflex Mini Cabbage Hybrid. We've never tried that one, so let us know if you do:
Chinese Cabbage/ Pak Choi Hybrid: Easy to grow, excellent for authentic stirfry
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):
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.
Attribute Hybrid Cauliflower is good for container gardening.
Chard: Harvest like lettuce; keep it cool. Great cooked like spinach. Why not try this colorful variety; Bright Lights Swiss Chard.
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 below), Johnnys-Diva, Sweet Success, Burpless, Bush Champion

Beauty Heirloom; 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.
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 Bush Beans; but it's hard to beat the flavor and
tenderness of Heirloom Kentucky Wonder pole beans. Give 'em a trellis and let 'em grow!
Seeds for your indoor vegetable garden:
This fascinating website offers a great selection of heirloom seeds, well packaged to last for years:
Herbs: see Herb Page
Lettuce: see Growing Hydroponic Lettuce
Onions: Spring onions; green bunching; sow heavily and thin to an inch apart. One pot sprouts dozens of onions.
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, Burpee Peas-In-A-Pot Sugar Snap Peas:
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, Heirloom Sweet Chinese Peppers
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
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. We like Heirloom Bloomsdale Spinach.
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.
Try Hybrid Pic-N-Pic Yellow crookneck squash or Fordhook Bush Zucchini.
Tomatoes: see Growing Hydroponic Tomatoes.
