itsystems that could in theory work if these work on propane, but i wouldnt do it, co2 has to be implemented in a controlled manner, i think those fumes would be way too much for a small growroom. My propane setup is very simple and works great, ive tried it before but didnt really complete the experiment, but i could definitely tell they were doing better with it. If u wanna try it get a coleman propane thing for camping, put it in a SAFE place, its an open flame after all, and put the flame to minimum power, but make sure the flame is burning blue, cause a yellow flame means carbon monoxyde, wich is a deadly gas and does nothing for ur plants! i was thinking of enclosing one in some kinda metal box and welding it there somehow, just like a commercial co2 generator, but much cheaper

Torchthatbird: You were right, i read the units manual and its exactly like you said, if you put it on max it shuts off the air intake, but any other setting has air coming from the outside WOOHOO no need for an exhaust or intake anymore

perfect run it on max all the time then and use co2

actually come to think of it ill need to have a carbon scrubber and ill probably exhaust it outside that same window to create some kinda negative pressure in the room. or maybe in a wall. anybody exhausting in a wall?

sleepyrz

you dont need to exhaust after the scrubber


keep the scrubber in the room recirculating and cleaning the air

dont exhaust your co2!

the fucker that sold me the ac unit forgot to mention that the button for fresh air exchange is broken! grrrr im freakin mad now, i guess ill just have to go with the scrubber inside room with co2 enrichment and no negative pressure for me. sux ass i didnt wanna have to bother with co2 yet, but i guess itll be a way to force me to do it...
