400W HPS Light vs. Power Bill

  1. Im currently growing 1 plant under a low watt CFL. it doesnt seem to be growing that fast so i would like to upgrade to a high pressure sodium light. my only concern is that it will noticibly boost the power bill. is this true? also i want to know how many plants i can grow under 1 400 watt HPS.
     
  2. thanks homie
     
  3. I'd say 4 good sized plants. Your electric bill will only go up about $10-13 at best. It's like having another tv on, it's not as bad as everyone thinks...
