WTF, my system ate 2.000Kw in 1 month? 250w hps?

No no, for 4 hours man....

Ok, even if it runs 24hrs, that's 6x of what we counter before. Either way it should be under 10kwh per month, right?

If you run it 24 hours a day you have to multiply the wattage with 24 hours and 30 days. Its that simple. So add the wattage of everything. Light fan..whatever and then multiply by 24 and then multiply by 30.

When you read the meter you have to take the last reading minus the new one to get the result. Or do you have something in it that shows month to month ? I know i dont...

316 watts x 18 hours x 30 days would be: 170,640 watts or 17.064 KW per month.

it could also vary depending on how old the wiring in your house is...

even house with meters in them that are digital and hooked to phone lines do guestimates and then real readings every 2 moinths or so. i dont know why they just cant read it via wire but guess they figure hackers can beat this with a fake line out via computer.
