Just out of curiosity, I've been following ur grow tm and other led grows in a way to find a perfect balance of HID and LED until LED takes over.
I've had several ideas with LEDs, from supplementing using them specifically pointed at budding sites (the wiring and weight of led's wouldnt be much after all) and also mix them between red wavelength and add a lil UV wavelength (specifically UVB) which would be cut off upon opening grow area to prevent harm to myself and the few others involved in grows. The more I watch the more I learn. Grow on!
