Hey guys, might be a dumb question but imma ask it anyways. When calculating how much costs to run my 400 watt, and 1000w ballasts do I include the bulb on my calculations as well.
400 w ballast X 18hrs X 30 days @ .10 cents kw = 22.5
Do I then count the 400 w bulb as well as an additional 22.5 a month?
So all together It would cost me $45 a month to run the system?
