I think 3 for two plants is really good especially if the outside ones u slightly aim in. I’ve been playing around with angleing the lights slightly to get the coverage I need. Working well so far.I've got 2 in a 2x4 tent and after my first grow with them going to get another for that space. 1 per is good but I dont think 2 per plant would be overkill in fact its probably just right. Just my opinion.
