I have a 400watt HPS and am just growing under that atm. Has anyone grown only with HPS? I am going to get a MH bulb, my digital ballast takes both types of lights, but I was just wondering if anyone has grown succesfully with HPS only. Thanks
I seen people do it before! I was gonna do it until I started to have heat issues. So, I decided to go CFL's for the mean time. I also heard that the HPS isn't enough of the right spectrum for veg, but I could be wrong.
