Ok so it would appear the temperature isn't what is causing my issues then. Maybe my lights aren't close enough. I thought 8/10 inches was close enough but maybe 2/3 inches is what I need. The lights are bare hanging bulbs (no reflectors or sheeting of any kind around them), there are 6 surrounding a 3 foot area and they are 6500k spectrum CFL's. Do I need more? I think I need them closer, but is 6 not enough? Obviously more refraction would help, but is that what is killing them, not enough refraction as in not enough light. They sure liked the 24 hours of light when I made that mistake. It was too much light, I think at that point.
