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
