Hello, ill keep it short and simple. i received a C02 meter i bought on Amazon for $60. Its "birdlink" ndir meter. I measured my tent over a 24hr period. Its about "700(Day) - 450ppm(at night)" . I bought a picnic burner at the dollar store for a $1. I rigged a shelf in my tent to set the burner over top my plants. With ample space in between everything so nothing catches fire!! The burner is also strapped to a tray sittin in water, tray strapped to the tent so it can be bumped and wont go anywhere! I know this is still quite dangerous but im home thru the day just not in my tent alllllll day. Ok. My C02 reading is now at "900ppm" (tent closed) ... so its safe to say something is happening in there. When i go in there after 30min im not gonna lie theres a bit of an odor almost immediately. Im running this experiment for a couple more days to see what happens . I might end up putting 2 burners in there after 2days if nothing negative comes about! Does anyone have any 2cents about my project? This is my first time doing this im open to suggestions! Pls dont be-little me im tryn to be type stingy with this product im thinkin itll coat about $10 a week to keep supplyin the burners . They last for 2hours straight .. thank y'all for tunning in!
