I'm still waiting on an HID bulb that pumps out nothing but 460 and 660nm radiation. Then we're going to see some insane growth. CMH is getting closer, I've watched it. I've seen CMH grows put out lots of great results.
khyberkitsune Reviewed by khyberkitsune on . Ceramic Metal Halide News CMH lights seem to very popular because of the improved spectrum over MH and HPS and the ability to use one bulb for the entire harvest. Problem was: no digital ballasts. Seems Philips just came out with a digital ballast (no link) designed specifically for CMH. Will try to find it again. Even better, Accendo Electronics just announced a dimmable (Glo Green)digital ballast for CMH. Accendo Electronics â?? GloGreen Digital Ballast (DHID) Products No pricing as of yet.
