    How much would your light bill cost if you ran a 400wat hps on only the 12/12 cycle ? so it would only be on for 12 hours a day for 8 weeks does anyone know about how much that is ? is there a way to calculate it ? Any help would be awesome. thank you .:punk:

    That's about 5 KWH per day....145 per month.


    multiply that by whatever you are paying for a KWH
