Well I'm a little strapped for time right now and am not able to go back over the bookmarks in 3 computers, looking for the green spectrum info. However I can give you a couple quotes I copied from various sources. I just put down random quotes concerning what colors a plant needs, and I don't know where each quote came from. I have read several things that indicate that the colors we usually think of as not necessary have a big influence on color, aroma and taste of fruit and flowers. Look up carotenoid and flavinoid to get you started.
Opie Yutts Reviewed by Opie Yutts on . CFL vs. HPS I'm currently planning my grow, which will be in an attic. It's not my house so I can't exactly start drilling holes everywhere, but I think regardless it's a little drafty so it may ventilate itself! Haha. There is a window which I could use though. But my question is: CFL bulbs REALLY are attractive because of how low their watt usage is - but can you really go the whole grow with CFL bulbs? I would like some tips on this, as well as the pros and cons. If an HPS is just simply better, then Rating: 5
