Another benefit of LED disovered- it's easy to reposition. Due to a variety of learning curve errors with aeroponics- controlling fog, heat, and pH, I only have 2 survivors. Both are same seed stock: one is 21" the other only 7", but a healthy, fat 7". No way I could get decent light to the short one (without sacraficing light to the top of 21), which impeded its' growth, and bud development. I made a makeshift riser so I could get it closer, but then it lost out on the timed spraybar, bubbler, and fog. This morning I had a brain-fart and experimented moving the LED horizontal to the plants. Because LED bulbs run cool, and not motion sensitive as filiments in MH/HPS are, I was able to unhook it from above the canopy and hold it so that the light was horizontal. My Ureka moment was seeing light flooding the many developing buds all along the 21s main stalk. SCROG without the hassle
