This is my first indoor grow, so I am kind of learning as I go along. So as me and my before mentioned friend were going over all the pictures of my plants he saw pictures of the water drops... I did not know this but those water drops with 600w of hps are burning holes in my plants like little laser beams as that light passes through that convex lens of that water drop. That is really something you don't see outside... Pests other things but not that. It is cool I really like growing inside hydro.
