Sorry if this is the wrong section but this question comes from a convo I had with some friends the other night.. Say you were able to grow a full size tree indoors (assuming you had the space, nessesary lighting, soil, etc..) and kept it under 18 hours of light and 6 hours of dark indefinitly. Would it still create tree rings? Would it loose its leaves? What is the mechanisms for these? thanks for any insight provided..
