Temperature required to grow lettuce indoors hydroponically-
- Since lettuce, as well as most leafy greens, are cool-season crops, it is best to keep the air temperature between 46 and 75°F (8 and 24°C).
If it is not in between these temperatures then you might see these symptoms-
- Bolting,
- Tipburn,
- Loss of colour,
- Poor germination.
Tap on bolting if you don’t, know what is bolting.
Do you know, just like another cold season leafy green lettuce starts bolting or turn bitter in taste if air temp. is high and light intensity is high!
Tipburn, death of the leaf margins due to Ca-deficiency, is another problem that is primarily associated with high temperature that stimulates rapid growth and slow water movement into the plant.!!
So now you can avoid that by giving them what they want!
Tip burn can be easily avoided by giving more Ca in nutrients and by selecting the right varieties which is less susceptible to tip burn!
High humidity kills lettuce by reducing transpiration which cools leaf surfaces resulting in less nutrient uptake and being highly prone to fungal diseases like botrytis and mildew.
Growth medium used to grow lettuce indoors hydroponically?
- Rockwool is preferred for germination and after germination, the cubes containing the emerging seedlings are set in the NFT trough or hole!
- The rooting medium can also be a mixture of various coconut fibre and perlite.
Dimensions for NFT to grow lettuce indoors hydroponically?
- In your NFT system, weather pipe or anything depth should be 1.5 to 3.5 inches and troughs are set on a slope of 1 to 2%.!
Flow Rate of nutrients in NFT?
- 0.5 L/min is the best to flow! It must be sufficient to keep the roots moist and spacing must be enough to avoid overlapping of leaves and roots
