A couple of questions?

I have read some of the threads on this already and I would like to get a better answer to my specific questions.
I have built the grow box. Installed a 400 wt HPS light, with cfl undergrow help and the seedling stage that can be raised and then installed around the walls once plants have grown. My first question concerns fans. I have 6 cpu fans 120mm at a .13 a rating. I have a 2000ma ac adaptor (2a right) .13 x 6 = .78 This should be well under the 2a that the acadaptor can handle correct?
My second question is concerning the power bill. Its a long story that I'm not getting into so the short version is I'm back where I never wanted to be. The power bill went from 486 kwh in 32 days to 1293 kwh in 30 days since my first month back. I have a heck of an electronics setup for video games and computer stuff. I've done the math for the usuage of the grow box and its less then the difference from just my electronics. My question is if I shut down serverly limit my other electronics then start using the grow box the power usage isn't going to attract unwanted attention is it? They haven't knocked on the door yet so if 486 went to 1293 and then it stays there or goes back down (more then likely my computer eats more then 600 watt grow box) I should be in the clear as far as power company knows.

Wow guess I have forgotten alot in the 3-4 year hiatus. I could use a little wisdom if anybody is willing to give it.

You are not going to get caught from electrical usage as long as you pay your bill. As far as the power company is concerned you're just another good customer that sets his thermostat lower than other people. Worry about smell and ex's of all kinds, not electricity.

Dude your grow should be using 400 tops as it seems you already know. Anyway a jump like you are describing could be caused by something as simple as you started using your a/c steady due to the summer heat. Pay your bill and nobody would ever look at a jump like that. Just my opinion but it is based off logic.

Thanks guys. Been a while and in this town duesche cops ain't got anything better to do then hunt for it. I figured my power bill would be okay just wasn't sure. Now if i can get someone to reassure or tell me i'm retarded when it comes to the fan hook up. And the smell I have taken care of. Imma run carbon scrubbers. Probably more then I really need to be honest but better safe then sorry. Its the old spot I used back in the day. God I love it. Walk in completly unnoticable unless you know its there. I even couldn't find it sometimes when i was completely blitzed. I'm just updating things for better production now. Wisdom with age.
