Who has plants that are strictly under grow lights? What is your PPFD reading? Ive had the same set up but as I get more plants and need to play musical plants, I find placing them all on the right tier is getting tough with finding the right spot...for the right plant...with the right PPFD. Ive been messing around with it and now ive added individual halo lights to some plants. Any suggestions with light set ups to have as minimal lights as possible? I "think" if I added a fourth hanging light that would resolve my problem. Thoughts? Pictures for motivation? And please do not judge the picture too hard. Thats the result of two straight days of moving things around and still not knowing what I want. Lol
