@rutherford - thanks for the positive vibes
@wattsaver - i started with the leds pretty close in both phases, i found that further away made them grow taller, and closer was thicker and it didnt burn any of the leaves. then i got the big 250w led, it seemed at least 10x brighter than the 90w, and you can feel the intensity on your hand, not same as hps heat, but like a large laser of energy. when i had my 2 big big super lemon haze and pineapple express plants, i had the 250w led about 2" away from the top of the colas. every few nights the colas would be touching the glass with no noticeable burn. since i lost those plants, i decided the LED would be better off vertical to fill out my white rhino, since it was the only plant that survived the drought and never got to be under direct light until recently. this has payed off as the entire plant now has grown about twice as high and the whole plant has heavy budding and crystals top to bottom. so i would definitely like to see a comparison that can show what the best distance is, but ive had such great crystal action and growth when the lights are as close as possible, i dont think i could try 12"+ without wondering if im losing too much lumen. i have the T5 and LED so close to my white rhino plant that the fan leaves would get burned but the buds got fatter so i didnt mind doing this. i just started the 2 week pre-harvest flush, i decided to trim off the fan leaves and let the buds get more light.
