How much did your electricity bill increase?

Your electric company is creepy.

This.

And no, a 4 tub rack is like, what, 60 some odd watts.

Also your electricity company may notice these things because from my understanding they watch for increases in power usage in case people are growing pot indoors.

Also a tank with a 30 watt lamp and a UTH would probably turn out to be like 60 watts total, meaning you're looking at the cost of an additional light bulb.
