I have 2 180's and 3 500 watt spectras too now. do u have a journal using yours? id love to check it out
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
