To answer your previous question about what color spectrum (If you still wanted to know). I am doing a CFL grow (well until next week when my MH/HPS Light gets here) the typical set up would be 6500k (daylight) for seedlings/vegging and 2700k (soft white) for flowering. I have 7 seedlings all under 6500k bulbs, 2 inches from the tops and the stems are perfect. I have one that stretched and I have no Idea why but it did...Temps are at 78 contantly.
