lets say a 1000w hps and a 600w hps. how close is too close for the plant? i can easily put a 600hps like 6 inches away from the tops with no ill effect from the buds and the temps are steady around 78-82..(air cooled hood) (i even taped a thermometer to the glass of the hood).. the 1000hps is around 9 inches from the tops of the bud and the same temp around 78-82.. im assuming that if the plants are healthy i could even drop the lights closer?? i see all these tests on different bulbs and led lights and they all test at around 36 inches. is there a reason that there testing at 36 inches? im just curious because i have moved my lights up to 14 inches before and my girls didnt like it and went into shock and got all droopy on me. as soon as i put the lights back to 6-8 inches they perked right back up. i would just like to know if im stunting the growth by having the lights too close and i dont realize it or are they alright being so close without burning them. thanks
