the part holding co2 will be sealed from all leaks, and since co2 is a very dense gas it tends to pool on the bottom, only the very top of the box is vented with a small 50 cfm fan to keep temps under 90 and above 85. and i honestly cannot understand people citing a co2 "calculator" for the...

which is why a calculator is pointless in the first place. you dont want it to reach 1500(in my case 1100) right away you want it to take 1/6th of an hour or 10 minutes to reach that level. if you have a monitor, solenoid valve and a controller there really is no need to use a calculator. that...
