How much did indor growing impact you electric bill? and how many plants are you growing? about how much do you spend on the lights, fans etc. a month?
i'm growing one plant and my bill has gone up a jazillion dollars this month alone. this is a silly thread topic...it's been discussed ad nauseum. there is no way to really speak about this in a general way as electricity rates vary, lighting schedules vary, etc ....even among those with similar set ups. you should use the search function to see the other answers to this topic....
