Start Planting

Lettuce

Beginner
30-45 days · 60-70F (15-21C)

Lettuce prefers cooler temperatures. Avoid summer heat which causes bolting and bitterness. Indoor growers can produce year-round with climate control.

View Plan

Basil

Beginner
25-35 days · 70-80F (21-27C)

Basil thrives in warm conditions and strong light. Pinch flowers to keep plants producing. Grows quickly and is ideal for beginners.

View Plan

Spinach

Beginner
25-40 days · 55-68F (13-20C)

Spinach is a cool-season crop that bolts quickly in heat. Best grown in fall through spring indoors, or year-round with good temperature control.

View Plan

Kale

Beginner
50-65 days · 55-70F (13-21C)

Kale is cold-tolerant and produces for months with continuous harvesting of outer leaves. One of the most nutritious crops you can grow.

View Plan

Cilantro

Beginner
21-30 days · 55-68F (13-20C)

Cilantro bolts quickly in warm conditions. Succession plant every 2-3 weeks for continuous supply. Best in cooler months or climate-controlled spaces.

View Plan

Mint

Beginner
30-45 days · 65-75F (18-24C)

Mint grows aggressively in hydroponic systems and is nearly impossible to kill. Great for beginners. Harvest frequently to encourage bushy growth.

View Plan

Herbs (General)

Beginner
25-45 days · 65-75F (18-24C)

Most culinary herbs (parsley, dill, chives, oregano, thyme) do well in hydroponic systems year-round with adequate lighting.

View Plan

Tomatoes

Intermediate
60-100 days · 70-80F (21-27C)

Tomatoes need strong light (14-18 hours), support stakes or cages, and regular pruning. Choose compact or cherry varieties for indoor growing.

View Plan

Peppers

Intermediate
60-120 days · 70-85F (21-29C)

Peppers love warmth and strong light. Start seeds early and be patient, as they take longer to mature than leafy greens. Both sweet and hot varieties grow well hydroponically.

View Plan

Strawberries

Intermediate
60-90 days · 60-75F (15-24C)

Strawberries need good airflow and pollination indoors (use a small brush). Day-neutral varieties produce fruit continuously and work best for hydroponic setups. Note: 60-90 days to harvest is from transplant, not seed (seed to fruit can take 4-6 months).

View Plan

Cucumbers

Intermediate
50-70 days · 70-80F (21-27C)

Cucumbers are vigorous growers that need vertical support. Choose compact or bush varieties for indoor systems. They need high humidity and consistent nutrient delivery.

View Plan

Microgreens

Beginner
7-14 days · 65-75F (18-24C)

Microgreens are the fastest hydroponic crop, ready to harvest in 7-14 days. Grow year-round on any windowsill or under basic lighting. Perfect for continuous planting.

View Plan

Bok Choy

Beginner
30-45 days · 55-70F (13-21C)

Bok choy is a fast-growing cool-season crop. It bolts in high heat, so maintain cooler temperatures. Baby bok choy varieties mature even faster.

View Plan

Arugula

Beginner
21-35 days · 55-65F (13-18C)

Arugula grows fast and has a peppery flavor that intensifies with age. Harvest young for milder taste. It bolts quickly in warm temperatures.

View Plan

Swiss Chard

Beginner
40-60 days · 60-70F (15-21C)

Swiss chard is heat-tolerant compared to other greens, making it a good summer option. Harvest outer leaves for continuous production over several months.

View Plan

Green Onions / Scallions

Beginner
21-30 days · 60-70F (15-21C)

One of the easiest and fastest hydroponic crops. Can regrow from store-bought scallion roots placed in water. Harvest by cutting above the root base for continuous regrowth.

View Plan

Parsley

Beginner
30-45 days · 60-70F (15-21C)

Parsley is slow to germinate (2-3 weeks) but grows steadily once established. Harvest outer stems first to encourage new growth from the center. Both flat-leaf and curly varieties do well.

View Plan

Chives

Beginner
30-45 days · 60-70F (15-21C)

Chives are virtually maintenance-free once established. Cut above 2 inches from the base and they regrow quickly. Flowers are edible and attract beneficial insects in outdoor setups.

View Plan

Watercress

Beginner
14-21 days · 55-65F (13-18C)

Watercress is a natural water plant that thrives in hydroponic systems. It prefers cool temperatures and partial shade. One of the most nutrient-dense greens you can grow.

View Plan

Pak Choi / Tatsoi

Beginner
25-40 days · 55-70F (13-21C)

Pak choi and tatsoi are fast-growing Asian greens that do well in cool conditions. They bolt quickly in heat, so grow in fall through spring or in climate-controlled spaces. Baby varieties mature in as little as 25 days.
