I have 4 year old Viparspectra 300W led grow lights. I have 4 in a 4x4 tent. They seem to do great in veg but I am getting low yields at harvest and think that it must not be enough light in flower. Is there something I can add to help what I have or do I need to totally switch out? Trying to be cost effective with what I already have but know these are older technology. Appreciate ideas!
