you raise some excellent points here. IMO I went with the 400 watt 12 blend phosphor induction and the results from veg-bud were on par with my hps grows. the LEDs simply do not have adequate energy with a 300 ma driver and the 700 ma driver burns leds out to fast. LEDs also have heat issues with the 700 ma drivers and not enough canopy penetration.

I'm very happy with the yields and the 400 have replaced my 1000 w hps

LED/INDUCTION Grow Diary Induction/LED Grow Diary Started on Tuesday 15th June 2010 Equipment What i have found especially when I got started was a complete lack of understanding of the little things you need and if they are not there or you forget them, everything takes time. This time around everything was ready. Tape, nails, extensions, wire,tools, pots. No running around, no stress and if you eliminate stress you eliminate a lot of risk. I have listed everything used. Cost would be approx £1500. 1 XL Rating: 5
