the color of light
I read with great interest the discussion on red and blue LED lights in another thread. Much of it was way over my head. So I wanted to simplify the answers for all of the unscientific folks like me.
There was a lot of discussion on red being the better spectrum with blue mixed in, but I thought blue is better for growing. Don't you always read that you should use cool fluorescents? Those are in the blue spectrum aren't they?
I've been growing peppers and herbs, now lettuce, under fluoreescents for a couple of years. Everyone over in the pepper forum says you can't get peppers to flower and fruit under lights, but I never had a problem. But I would like to always do it better and cheaper.
So should I keep using cool fluors, or should I look into LED's? And what color?
