well that movie would talk alot about temps.. hps and heat producting lamps made the novice grower succeed in pretty good %'s b/c of the heat they created with the lights// with the use of leds there is little to no heat discharge to keep the plants warm soo u most provide a sutible eco system for proper growth... with the root temps beening off on a led setup your pretty much screwed as in possiblity of success..u still need a able inviroment..this can be solved with like a 20 $ heating pad if your area is not the warmest....
