Nov 19, 2020 · Many of the leafy greens are grown using hydroponic production systems including nutrient film technique (NFT) and deep water culture. Peter Does, product specialist hydroponic lettuce and spinach at BASF Vegetable Seeds in the Netherlands, has been doing product development with lettuce for controlled environment production for nearly 25 years.
We're growing rex butterhead lettuce in a NFT hydroponic system inside under lights. We've been battling potato aphids w/ Nuke em a omri listed food grade insecticide that uses citric acid and yeast . we're now seeing necrotic spots aa well as yellowing of the leaves the last few days.
Most hydroponic lettuce systems are placed outdoors with about half having hail netting supported above the crop. Another key characteristic of hydroponic lettuce systems is the use of nutrient film technique (NFT). In this type of system nutrient solution is supplied from a tank to sloping channels supporting the growing plants.
May 23, 2019 · NFT channels are mainly used to grow leafy green plants with a short growth period. Bibb and leaf type lettuce are an ideal plant for such a system, but you can develop other leafy green plants such as spinach, broccoli Raab, and certain herbs. With better planning and care, any plant can be successful in a Nutrient film aquaponic system.
As the water passes through the pipes, it feeds the bottom roots of the plants in the net pots. So the roots get water and oxygen for fast and healthy plant growth. The system can sustain 24 plants.. You can grow most plants in an NFT system, including lettuce, tomatoes, leafy plants, as well as fruit such as strawberries.

Sep 05, 2020 · If you want to grow hydroponic lettuce, pick a lettuce variety and a water culture system for your setup, such as NFT or Ebb and Flow. Grow lettuce seedlings outside of the water culture system, and once they are around 2 inches tall, transplant them into a net pot and place the pot in the reservoir.
A nutrient film technique system equipped with an automatic pH and water level control system was used to determine water and nutrient use by lettuce (Lactuca sativa cv Sitonia). The composition of the nutrient solution was controlled manually based on daily measured nitrate concentrations and known uptake ratios.
