Yeah, if they ask I'll just say we stopped using the fireplace and got a space heater... those are 1000W from what I can tell and it's probably not unreasonable to run it for 18 hours a day. I'm also going to say I got a new PC since it's XMAS time!
Bout to give them a call. This is a legal grow anyway, but I have a few more plants than I should just to make sure that I come out with enough healthy ones at the end!

I think the problem was that I used so little before!!! I should've started amping it up leaving shit on all night awhile back!
