So ive got a bottle regulator flow meter gas solnoid and timer i do not have a co2 sniffer (not worth the investment to me lil 400w hps grow) ive done some research and just need a few things cleared up For arguements sake and to make the numbers easy lets say that my grow room is Air-tight and is 10x10x10 (feet) so 1000 cubic feet, and im aiming for 1000ppm co2 i understand that i will need to release 1 x cubic foot of co2 initialy to achive this (disregarding the initial 300 odd ppm of co2 already present in the air) is this correct so far?
Or If you have come across a thread or website that could be of use this would be much apreciated thank you
