my 400 watt hps makes my bill go up by about 9 bucks a month!
jacked420 Reviewed by jacked420 on . 400W HPS and electricity cost??? i have recently purchased a 400 watt HPS and MH from HTG with a growbright MH bulb and a agromax HPS bulb. I plan on putting it in a closet that is about 3'x5'. I am looking to see if anyone would know about how much that would run my energy bill, also if something like that in an average sized appartment would be flagged by the local authorities??? Also if anyone has any experience in the same situation i could use some temp and ventilation advice.... Rating: 5
