Maintenance: The ideal water temperature for hydroponic lettuce is between 20 to 25 degrees celcius. If the water temperature gets too high, the nutrient solution will not hold enough dissolved oxygen, but if the temperature is too low, the metabolism of the roots is slowed down and plant growth can stall.
Can you continue to grow hydroponic lettuce?
Yes. Hydroponic lettuce will regrow if you replant the stem or stump. Provide it with enough nutrition, plenty of indoor artificial light or a controlled outdoor environment where it gets just enough sunlight.
