Thought I have been pondering for a while and looking for input from others who have actually done it.. We’re you doing hydro or some other method? Scrogging or just staking the plants up? My main thought is that if defoliation under the canopy is due to lack of light penetration wouldn’t adding say a few led bars under the canopy help? Wouldn’t necessarily need to be on the floor, mounted on the walls pointing into the canopy should boost yields a tiny bit I would imagine.. I’m open for any constructive criticism or open thinking
