Hey Haze/Dr. Dread,
I was wondering if you or anyone had a rough formula for how many 2 Liter
bottles per plants? You mentioned you had 3 2L bottles...?

Also when you say make sure the air line has enough holes in it are you stringing a plastic hose across multiple plants in which you have it plugged at the end and just poking holes in it? Similar to a drip irrigation system?

My primary concern about monitoring the CO2 is CO2 in heavy PPM's can cause death in enclosed spaces which I am debating as to whether I truly want to add an exhaust to my room or not but I don't want to have too much CO2 build up before the plants can use it to where it could be at dangerous levels.

Rooms with exhaust in some senses waste CO2 vs. a sealed room that can re-circulate unused CO2.
