set it and forget it carb method question

Happy Easter everyone, i have a question. I have a  lager in my keezer and i set the psi to 12 to carbonate. My question is should i leave it hooked up for the whole duration of the lagering for 6-8 weeks? or should i unhook the gas at some point to avoid over carbonation? cheers have a great day

I would leave it right at 12 psi. It will not carbonate past that point, no matter how long you leave it.

It depends. At 12 psi and 32F you’re going to get a higher level of carbonation than serving temp (40F-ish) at 12 psi.  If that doesn’t bother you or if you’re lagering at 40*F-ish then go for it. If it does adjust accordingly using this chart: Force Carbonation Chart - Kegerators.com

Good point on the temp component - I hadn’t considered that!
