1000 watt HPS at 11 cents per kilowatt works out to about 20-30 bucks. I used to do the math, I'm getting lazier.

Hey, think about what you would yield at 1000 watts, and you won't give a second thought to the electric bill.
graph Reviewed by graph on . MH and HPS lights, expensive electric bill I know lot of the people who have grown and have told me that there electric bill went up, of course because of the high watt of the MH and HPS lights. that's why i was thinking it be better for me to get flourescent lights, yet everyone on this board seems to say that it's worth it and you'll make your money back. and i was just wonder maybe you guys have some specail way, or special HID lights that use very less electricity. just very confused and wondering, thanks very much.
