Leave the 600 a good 2 feet away from the seedlings. Move it closer as they grow, but no closer than about a foot.

As for photoshop, click on Help on the main menu bar along the top. There should be an option to resize images.
Perp Reviewed by Perp on . Sick Seedling! One of my little ones (1 1/2 weeks old) has yellow splotches on its first set of leaves, but the other two seem fine. I moved the light higher- it was about two inches away, and now it is six inches - in case that was the problem. The light is a 40w warm flourescent. Can anyone tell from this picture what is wrong with the baby?:( Rating: 5
