Not sure if this question has been answered or not....how do I avoid the spikes in my electrical bill? The jump in total consumption each month? I'm thinking of using a generator during certain hours along with knowing how much total wattage i'm using.

Electric company came to my home a few years ago and was wondering why my usage jumped so much installed a reef tank that burned 2400 watts with lights and pumps asked them if they would like to come in to see it and they declined never seen them again but just that raised concerns to have them come out and snoop around.

when u mean spikes do u mean every time u grow? u can try being more consistent when growing, like having separate rooms for veggin and flowering.

i pay 1400 monthly bill and have no problem. I also explained my 800 gallon saltwater fish tank with calcium reactor, 4 x400 m/h, 1/4 h/p sump pump which returns my water from the refugium bac to the main tank,but not before it goes threw my 1 h/p chiller to keep my reef tank at optimum temp. and my quantine tank in my garage. if they dont like that one you can always go with the recording studio in your garage.

POWER USAGE:
On average, a light system will increase your electricity cost from $8 to $20 per month—the exact amount depends on the size of the system and the number of hours operated. Make sure your grow room’s power circuit can handle the power draw. For safety reasons, do not exceed 75% of the rated ability of the fuse/breaker (for example: use no more than 15 amps on a 20 amp circuit). To calculate your cost, multiply the bulb wattage X hours of operation and divide by 1000. This figure is the number of kilowatt hours of electricity consumed. (Example: a 400 watt bulb running for 18 hours will use 7.2 kilowatt hours). Check your power bill for the cost of each kilowatt hour. Then multiply the number of kilowatt hours by the cost of a kilowatt hour (K/hr) to arrive at the cost per month to run the light in your area.
