Whats up everyone. So here is a picture of the top of the Nebula, Im trying to figure out the best time to switch to 12/12. Should I let the tops grow more before switching? Here are the heights: Acid-18", Nebula-17", Wappa-14". Also the top of the Acid is about 9" away from the light, should I move them further away? And just got a nice little surprise in the mail yesterday. Thinking about planting one and doing 12/12 from seed when I switch these girls over.
