Why is my hydroponic lettuce not growing?

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.

Why are my hydroponic plants growing so slow?

The pH level of your nutrient solution is one of the most crucial aspects of hydroponic growing. When growing plants in soil, the soil itself acts as a pH buffer and prevents rapid changes in the pH level. This means that pH issues are slower to develop and can be dealt with more easily.

Why is my lettuce not growing?

Insufficient soil moisture or overly wet soil can both result in poor growth and wilting. Lettuce suffering from drought stress wilts quickly and fails to put on new growth. Wet and soggy soil causes the plant’s roots to drown and rot. Leaves may begin to yellow and wilt, or the whole plant may become stunted.

Will wilted lettuce come back?

Lettuce wilts because it loses water, so the key to reviving it is to put the water back in. We’ve had success simply soaking the wilted leaves in ice water for 30 minutes. A REFRESHING DIP: Soak lettuce in plain ice water to restore crispness.

How do I stop Tipburn?

Avoiding inner leaf “tip-burn” in lettuce

1. Fertilize with adequate amounts of calcium. First check that adequate calcium is supplied in the nutrient program.
2. Calcium foliar sprays.
3. Modify the growing climate.
4. Avoid antagonistic effects from other fertilizer nutrients.
5. Avoid high soluble salts.
6. Select resistant varieties.

Can lettuce get too much light?

Lettuce is generally considered to be a full-sun vegetable, and will germinate and grow more quickly if it’s given as much daylight as possible. That said, it will tolerate partial shade and may even benefit from it during warmer weather.

What is a NFT hydroponic system?

The NFT (Nutrient Film Technique) System is a hydroponic system great for growing leafy greens and keeping them at ideal nutrient and climate levels. This level of control can help reduce production time and increase the quality of the crops.
