Actually it was pretty funny, a few months ago I went out to smoke with a friend and a friend of his I knew from high school (5 years ago). We hung out, shot the shit and I realized that the friend of the friend was actually a daily smoker living with a girlfriend who either didn't know or didn't like the idea of him smoking. Like me he works in a white collar environment and like me he keeps little "kits" all over. My "kit" has eye drops, "body spray", breath mints and a change of cloths (including undershirt). I have one stashed in the house, one in my gym bag, one in the car and one at my office.
Back when I was really smoking on the DL (wife didn't know) I was more like James Bond than anything else. Hell I guess I kinda still am, I get up at 5:00 am to sit in a shack outside the house and watch 3 monitors (left is tv/movies/youtube, middle is for internet/gaming and the right is for my 2 network cameras to make sure the little lady is not walking outside).
I am grabbing some stuff for a DIY coffee can filter from walmart (I am CHEAP) today and eventually I plan on building a "decontamination area" where a few pretty decent sized sized squirel cage fans blow straight down right by the door. A few seconds under those babies would get rid of a lot of the stink. I am also thinking about a system that would actually work in reverse by using 2 big fans to suck all the air out of the shed, run it through a carbon filter and then vent to the outside.
Winter will be tough, while I do live in the south it tends to get pretty cold here. Last year during the dead of winter I was growing and my 400 watt HPS actually generated enough heat to keep the whole shed warm, even though it was only on for 12 hours. I did end up having to shift it to run at night which was a huge pain in the ass (only had like a 1 hour window to work in the flowering room). If I have issues this year I will figure it out, no telling how but I know I will and probably for under $30.
