I increased my light from 40% at 21.5 inches to 60% at 26 inches I don’t have a cell phone or light meter so I have to guess at my ppfd I know at 60% and 21.5 inches in the center of my tent it’s 619 umols at 40% its 420 at 80% its 812 and at 100% its 1000 umols so I figured 4.5 inches higher on 60% should be close to or slightly higher than the 420 they were getting at 40% 21.5 inches and I’ll just watch the plants for signs of light stress but I don’t think I’ll have a problem with these particular cultivars because Rasta Jeff said feed them the light give them all the light they can handle the light did I mention these plants love the light they want all the light lol that’s what he said about them in the GFYH podcast! And I also increased the nutrients to week 2 of veg!
