4 plants have began to grow. 1 plant in perlite and 1 plant in rockwool have failed to grow. We placed new cherry tomato seeds in each failed cup.
We placed 1 cherry tomato seed in each cup. We have a total of 6 cups 3 with rockwool and 3 with perlite. The drip was adjusted to a level appropriate for germination. There were several leaks on the adjustment joints. Teflon tape was used on the threads of the joints to stop the leaks.
