Indoor cannabis cultivation and energy consumption

A typical indoor cannabis grow uses multiple lamps that each run on 600 to 1000 watts for the lamp plus 120 watts for the ballast, plus a load of fans, pumps, filters and even air conditioning to cool everything down. These attach to breakers that run on 120 or 240 volts and each of them draws from four…
