The cups look small and they are only filled halfway with potting soil. Between the plant lights and the needs of the plants it seems the cups would quickly dry out. Several of the seedlings appear to be dried up already. My gardening buddy has an LED grow light and what surprised me was that with his he had to keep the lights 2-3 feet above his seedlings. Are the bulbs in the clamp lights LED or incandescent? Do you have a hard time keeping the cups watered? Inside the box with all the lights just seems like would be a really drying environment.
