Oh, I believe it...these panels seem uber legit. I find that they can show comparable growth to a 600w HID...nothing more. For only drawing 180w each panel, I'd say they're great. Would you say you'd get poor results without CO2 supplementation?
I can pull between a z and 2 z's a plant with my GLH Spectra 180 without CO2. I'm sure if I added it I could be pretty competitive with a 600 HID. Though the most I've ever hit with my 600HPS was 3 zips a plant, so I'm already almost competitive, and with 1/3 of the power. The Magnums appear to perform just as well if not better as GLH
Wow bro, those look dence! Nice work with the led.
I read you had those CO2 green pads. Howed did you like em? I mean I know you said they helped but is it something you dont see growing without?
