Thanks man any advice is good advice!!!!

I was thinking of a 3 week veg or until i think they are tall enough....i'm not sure yet like i said i've never done this before and i want to keep the lowest key i can....I'm probably gonna make my own carbon filter and vent to the attic...(to minimize heat pollution)...not sure what fans to use... i guess i could go with a simple duct booster fan....for exhaust and intake...lots of variables....if you could point me in the right direction of a thread that would be much appreciated....i'm new here obviously but i'll do my homework....oh, i dont want to use to much electricity i've heard that about 1000watts continuously will give the electric company a reason for suspicion (here in the states) just tryin to keep it low key
