The seedlings have been about an inch away from the bulbs since they germinated. That's one reason that I thought that I should replace the bulbs. I have always used a combination of warm white/cool white bulbs with good success in the past. I was under the impresion that you only need to use the full spectrum guys for flowering plants-when you want them to set flower. I did move up to GroLux bulbs (2 in each fixture)-and I did move the flats more to the center of the shelf. I like the idea of the emergency blanket-thanks for the suggestion! I also have a fan in place now (not blowing directly on them, but pointed up) I left my heat mat on on the lower shelf, the soil temperature on the tomato shelf with the heat mat off has been about 65-70 degrees with the cover open. I think I will let the cover drape down over night because it can get a bit chilly down there:)
Thank you all!!!
