I've been having trouble with keeping my seedlings wet enough to avoid cooking over night with my lights. I bought 75 watt plant lights, and am using potting soil in my starter containers. (Why is potting soil so difficult to get wet? (The water collects at the top and then drains through the bottom, and the soil is never wet afterward for some reason.)
Anyhow, I have the cone shaped reflectors and 4 bulbs above my trays and if I leave them on for the normal 16-18 hours a day, they always cook my little seedlings and I end up starting over. The lights are around 3-4 inches above my plants right now. Any advice?
