Listen, power fluctuation is absolutely no problem. If you're running an indoor op for 100's of plants, fine but I bet any money you aren't.
Unless you have reason, and viable reason to believe that the police are watching you, and I promise you if they ARE you have more things to worry about then how much power you're consuming, but if they ARE than they're not going to give two shits about electricity. Big screen tv, multiple computers, giant freezer and a fridge, alarm clocks, satellites, furnace, heating <- if it isn't gas all take up electricity.
A big screen television while turned off consumes more electricity keeping its capacitor running than running a 4-8 plant system. The power company is a business, they like money, why would they care? You bought a television, you're running servers in your home, you like to order cows by the half and keep them in small industrial freezers, w/e the shtick is unless they have reason for suspicion, you won't look suspicious.
Remember, the key to not getting caught growing is to look like and or seem like you aren't growing at all, so if your power consumption isn't outside of even the most stretched out norm, what's the worry?
Don't believe me? forget for a second the amount of power, don't believe when it's off it consumes? use your remote control.
Theres batteries in your remote, if your televisions off, how is the electricity from the remote getting the signal to the tv? Thats right. It's always on unless you unplug the bitch. It's definitely the way to do it I won't deny it, but 1. it's been thought of and 2. again, unless you're doing something more grand then a personal grow, all you have to really worry about is warrants. Or at least worry about anything that would force the police to facilitate one.
