I cut my bill down to 267 (past month) and that is 4 1000's, 6 600's, AC unit, 4 50 gallon rez's, 4 80w air pumps, 4 8 tube flouro's (412 or 512 watts each), 1 4 tube flouro, asst'd cloning lights, 5 oscillating fans, 2 8 inch vortex....
I switched over to what we call Watt Watcher program....i pay .04 cents kwh from 10pm to 10 am and from 10pm friday night to 10am Monday is the .04 cent kwh, and .15 cents kwh from 10am to 10 pm monday-thursday. It would be hard to do probably with kids but most electric companies have these programs....i just checked I clocked in over 4000 kwh's on the low rate and 762 on the day rate, next month will be even cheaper cause i had to play around with how to dial in my AC unit and just getting used to this program...my bill would have been over 500 bucks otherwise. Here in CO they let you switch over for 20 bucks, and for the first year they show you your bill both ways and charge you the lesser amount...then at the end of a year you have to decide whether to stay on it or not...at the commercial place i am partners on we did the same thing and with a 3 ton AC unit going 6 100's on light movers, 3 aeroflows and a Tshirt dryer it was only 184 bucks...so both places are WAY CHEAPER, and the money we are saving is paying for our nutrients...one of the smartest things i have done with growing...
