i grew with 2 1000 watt hps...digital ballasts and hortilux bubls and my yields are very close and my meds are stronger...whats to figure out?

i don't need science to tell me my plants are healthier and producing better meds...there are a few folks on here who may be able to explain your question but again my results tell me everything. you are welcome to look at my albums and grow log. :hippy:

plus i am only growing with half the power i did from before and no heat to worry about or cooling!:jointsmile:
stra8outtaWeed Reviewed by stra8outtaWeed on . Importance of 460nm red LEDs? Here is something very confusing to me. Many LED proponents loudly proclaim the need for 460-470nm red LEDs over the cheaper 630nm LEDs. I understand that this better coincides with the accepted chlorophyll B absorption peak. So far so good. LEDs veg very well given appropriate wattage & color. So far so good. LEDs do not compare (generally) to HPS flowering as far as yield. (Please - let's not go off in that direction here. Thank you!) Rating: 5
