My buddy blessed me with a few clones about 2wks. ago. Today he stopped by to see if they were still alive. He said that I was doing a fine job and the only thing he would change would be "to lift the lights a little higher". My plants show no sign of stress from heat or light, (the light 400MH is close about 6" from the top of plants and my temp. at the top of the canopy is 79F) so I'm confused on why would I lift up the lights. He said that if I lift up the lights my plants would reach for the lights (I thought this was called "stretching"). All most all of the knowledge I have of growing (which is very little) I've learned on this Forum. And from everything that I have learned it tells me that he doesnt know what he's talking about. Do anyone agree or disagree?
