  1. Dont wanna run it up >.<
     
  2. um... i saw an equation where you can find out how much it is on the "ready set grow" video...don't remember the equation though. sorry
     
  3. find out how much a kilowatt per hour is on your bill and that's 1000w per hour...400w is that number divided by 2.5...it's usually like 20-30 bucks extra a month for 18hrs
