Hey, everyone. Well, after seeing many people asking how far they should have the light from their plants, and myself being confused about it at times as well, I went and looked up some info. I recently moved my light further from the tops of the plants thinking it was too close and contributing to the problems from accidentally over-fertilizing them, but I've seen some internode stretching and plan to move the light back down where it was before. This should provide everyone with some good information, and I think it'd be a good thread to make as a sticky up top. First, I'll put up two charts here showing the foot-candles put out at various distances. A lot of people talk about total lumens being important, and while light intensity is important, lumens and foot-candles are units related to what the human eye can see. Plants don't "see" light the same way we do... but more on that in the next post.
