ive been looking at this thread forever and still tryin to wrap my head around it. im staring at my power bill and it says the first 1000 kwh is just about 6 cents, and anything over is.07. but the in the next column its sayin the same shit but it says fuel charge. i have an electric stove, heater, everything is electric. i guess maybe hot water heater isnt but the column for this fuel cost is the same price almost as the energy cost. wtf? bottom line, im trying to see with 3-4 nice plants, either a soil or basic hydro setup, 400 hps running 18 for veg and 12 flower, whats my cost a month gonna go up? being as i alreadypay close to 400 a month in the summer, and average 1800 kwh a month. please let me know
