Just got the Sunshine Systems GlowPanel 45 for Christmas! But ... is it good for starting seeds? I want to grow some lettuce indoors, start some seeds for the veggie garden soon, and maybe try a few perennial seeds. I could also rig up a florescent shop light if necessary... so is the Glow Panel (which seems to come with minimal instructions) strong enough for seed starting? Once they sprout, do I need to have the panel right down on the plants as I would florescents, or further up?
