Hey guys, looking at a lot of pictures from COBs growers on here, seems like everybody keep their COBs much closer than I do, what is the optimal distance from canopy? one reason for me to keep them so far away is I rarely move the lights, only the plants, and there are a few times where I had a short plant under a light that was hung like 4ft from the tops and plant still grew amazing nugs... I think the sweet spot isnt as close to the canopy as people think, am I right? BTW I am talking about 3590 cxb or vero29, I use both.
