How To Grow Hydroponic Tomatoes

Transplanting the Seedling (1)
- 22–24°C for Seedling
- Expect 10 Days to Germinate
- Around 100 Days To Mature
- Preferred Medium – Rockwool & Cocopeat

Preferred Medium (2)
- Rockwool Slabs
- Perlite and Cocopeat Slabs
- Dutch Buckets (130 × 15 × 7.5 cm)
- Grow Bags with Cocopeat

Temperature & Humidity (3)
- Air and root temperatures 30°C day time & 25°C for the night. Beyond 32°C poor yield
- Relative atmospheric humidity 50%
- Air movement through the plant canopy of 1 m/s is good as it keeps the plants actively transpiring
- If Temperature exceeds 29°C, use shade material pulled over the greenhouse

Nutrient Tank (4)
- The size of the nutrient tank depends on the number of plants you are growing
- Minimum 2 L of nutrient solution per plant per day should be assumed
- Tank Volume should be that much for 5 days. For eg. for 10 plants, tanks capacity should be 10x5x2=100L
- Submersible pump capacity about 1000L/hr. at 1ft lift and pumping height capacity at least 10 to 12 ft.
- The pump can be connected to black drip irrigation pipes 1-2 inch diameter

Irrigation Cycles (5)
- Young plants need 3 to 5 daily irrigations
- Fruiting plants under full summer – irrigation cycles maybe every hour during daylight and 3-4 times during the night
- Avoid stem rot by placing the drip irrigation line slightly away from the base of the plant (below root and stem joint)

Flower Pollination (6)
- It depends on the variety you choose
- Home growers can hand pollinate every other mid-day. However for commercial electric hand pollinators or introduction of bumblebees inside your greenhouse, should be done wisely according to the number of plants and greenhouse configuration
- You can expect fruit to mature from 40 to 75 days after pollination

Grafting (7)
- You can also do grafting with seedlings to create (two plants on one root system) or grafting onto a rootstock that has higher plant vigour
- Grafting is done at the seedling stage on 17- to 18-day-old plants

When to Harvest (8)
- You can harvest them once the fruit turns green or firm and pink
- The lower leaf turns yellow followed by a line between the yellow leaf stem and the green stem that line is the natural cutting point, use sharp objects to cut
- Yellow leaves are prone to disease so maintain proper aeration

Pests and Diseases Management (9)
- Sometimes hydroponic systems can also have pests or diseases. Never transplant soil-grown into your hydroponic system
- You should keep the growing channels and tank covered to prevent algae growth
- Keep the base of the plants dry with proper aeration. Note high humidity causes fungal infections
- Sterilization of the beds, nutrients tank, equipment and irrigation lines with a 10% chlorine bleach solution can eliminate any major pest problems on your farm
