630cmh do work! the growers choice master pursuit 500w is a beast… i am running 3 again, along with a 1k hps… cmh ftw
Given the summer electric rates I think I’m gonna hold off on another big grow attempt and just do the 4x4 with the 600w for now. Gonna hit lowes and grab some potting soil tomorrow. I’m doing this one cheap.
I dont know much about CMH lighting but they look like they give off a ton of heat compared to like a air cooled HPS where u can easily vent the heat outside.
