between the 2 post i have yet to see anyone state any PAR wattage numbers on LEDs, you may be hitting the correct spectrum but theres not enough power behind it, with a multi million dollar indoor horticulture industry why dont we hear of any big companies doing R&D with LEDs? bottom line is plants love strong light, i mean "sun basking plants" such as marijuana love it, go ahead and grow your house plants under LED's im sure they love the shade but i'll stick to my HIDs until proven otherwise
