  1. tryng to do some math here and i need some help. Just to make it simple, say the only thing using electricity in the house is your grow light. How much roughly would be spent monthly for one 1000w hps light running 24/7 for 30 days
  2. You need to know the cost per unit. Then use the arithmetic you learnt when you were 11.
  3. 1000W = 1KW
    600W = .6KW
    400W = .4KW

    Flower period = 12/12

    1KW x 12 = 12KW per light per day
    12KW x 30 (days in month) = 360KW hours in the month

    If you pay .06 cents per KW

    360 x .06 = 21.60 so your hydro bill will be $21.60 dollars more for that flower period.
