i've found that when i am deligent about turning off unused appliances & lights, it directly offsets my 1000w mh while in flower. in fact my elec. bill goes down a little. r
trippruss Reviewed by trippruss on . How many watts can I use without questions from Elec. Co. I want to set up a cabinet grow thats 8 feet long and 3 feet wide. I want to use a 600w and a 400w hps inside the cabinet. Air circulation is good. Heat not a problem. The only thing is how much electricity will this box use and will it raise eyebrows from the power co. or the cops? Rating: 5
