Uneven Lettuce Growth in NFT Systems
Regardless of the material you use to germinate your lettuce seedlings, it
is important that rooted seedlings make contact with the water in a nutrient
film technique (NFT) system. In this example, you can see variability in the
growth of several mature lettuce plants that was caused by seedling roots not
making direct contact with the film of water upon transplant and being stressed
compared to the other plants in the same trough. Periodically check roots to
make sure they are contacting the bottom of the trough and that they look
healthy.
