Ok so with the massive, rapid and abundant Co2, overshoot of the 6l and even the 5l (thanks mrduke) its a non issue. Got it. Sweet. I wonder if the 5l mrduke has would work but just take a bit longer and probably still overshoot?
I have a sealed room(s) kind of like yours in a way I think. Flower room then scrub to veg room and then back to flower room via a 3" thick Styrofoam 4'x4x4' ac air transfer chamber (all sealed)(except heat exhaust out the back) . Since the whole system is sealed and theres now abundant free c02
should I just leave all the fans on including the one scrubber fan/room transfer fans, recirc fans, etc all the time during day (co2 cycle) and nite as well? I mean shit its essentially free now so gas the whole thing during lights on and the residual can supplement the veg room...
Thanks for chiming back in mrduke and thanks for the info on the digi co2 monitor!
I am wondering also about your reservoir temps (or really if its even an issue?) as I will be doing the shady side 50 gal above ground res. too. No choice concrete....
This kind of internet grassroots shit just kicks ass! Whatever I do I try to do it as cheap as possible and do as much of the work myself as possible. I like being able to get items at hydro shops but i cannot afford to pay their retirement as well.
Their prices are not reasonable unless you catch some sale for big ticket stuff. For example a fucking burner (the smallest one 1G someshit) was like 4 bone with tax. WTF and no water cooling with that either. i can get a BBQ for a third of that. This was a discount hydro shop too. Anyway they are all making millions off the people selling their shit on Craigsbay. Dont get me wrong we need them as well as the dispensaries but they too overcharge everyone. So the message is "DIY"!
