LOL
I just finished the third treatment, in two weeks, of CO (carbon monoxide) immersion on my crop (26 plants, 6 strains),
a few days ago, to discourage males.
I use a kerosene heater. it has a chimney to burn the fuel more cleanly. I remove that, light the wick, and dense smoke,
reeking of CO(smelled like a parking garage), pours into the grow room. nearly KILLED me the first time, lol. so, I crawl to the door, and wait outside
for about 10 minutes, then crawl back in to turn off the burner, crawl out, shut door. go do smthing for several hrs. when I return,
the grow room gets aired out thoroughly.
I believe you're right about smoke and tobacco/nicotine...and not to belittle your opinion, but, it would take like a year or three for second hand smoke
to kill a mouse(not actual data) and you're worried about something that will be dead in a few months anyway.
I wouldn't even sweat it man. smoke away! IMO
