Had a timer but was crap so I tossed it I turn lights off at 5:30 am when I leave for work and on again at 5:30 after im home manually at exact time just to make sure that there's more controls than variables, as far as looking droopy the pic was taken onto seconds after light was turned on so they hadn't had time to waken up. I water once a day alternating days with advanced nutes, and only advance nutes products. Medium is foxfarms quality soil mixed with coconut coir.water till the pot fills like it has weight and not again till it's light while observing common sense as far as too much water or not enough,water quality is r.o. Water or reverse osmosis water ,which is purer than filtered water with better content. No light leaks but the box.at work out of sheet metal with full welds solid penetration (no light enters or escapes), each day plants produce new growth at crazy rates,bushing out making stems and leaves,this is by far not my first time growing only first time using l.s.t and I know it's not harming or stunting the plant at all ,the growth shows it,.. Im out of ideas curious if any of you have dealt with this and saw results,as far as the health of plant it's vibrantly green,bushy,short,hairy/fuzzy,and uniform leaves,stems are nice fat and sturdy with clean stomatas and sparkling white roots
