Hey so I picked up three of these ballasts on Craigslist for 5$ a piece. Curious if I can run both 400 watt hps and mh out of them? See pics and lemme know what you know.
Hello. I am acquiring a metal cabinet from work with dimensions of 18"x3'x 6.5'. I'm curious what the most affordable lighting set up may be and also- how you would set it up if it were yours. I plan on o or three plants.
