Please help, I have my seedlings under T8s right now and was wondering when I can/should switch them to my stronger clfs? Below are a couple of pics from last night. They have grown a bit since then.
I don't really get what's to be confused about on the lighting end of things. You're trying to emulate the sun. So long as you can afford the light bills, and keep the temp under control, seems to me that you could go hog wild.
