appreciate all the new feedback as well!
some follow up questions:
so if i carb my keg at room temp, lets just say its at 15 psi
if i put the keg into the fridge to chill afterwards, will the psi of the keg change from 15?
if it does do i then look for the proper psi to adjust to for the given new temperature?
also, would also putting in the room temp co2 tank have an effect on the psi?
I have a feeling once i have a keg i might be able to answer most of these though -.-
Say your room is 72F and you want to carb to 2.4 volumes of co2. In this case, you will set you regulator to 28.4 psi and leave the keg attached to the regulator at that setting in that temp room for 10-14 days. Now it's carbed.
Next you move it to the fridge. If you disconnect from the regulator and place it in the fridge at 39F the head pressure will drop to 10.7 psi but the amount of co2 in the beer will still be 2.4 volumes.
When you are ready to serve you will want to connect to the regulator. You don't want to change the carbonation level so you set the regulator at 10.7 psi serving pressure.
I made all the above calculations from Beersmith mobile.
In reality 29-30 psi at room temp is fine. When placing in fridge, turn down the regulator to 10-11 psi.
One more thing, you are better off carbonating in the fridge at serving pressure. It's less complicated. Just put it in the fridge, set the pressure to 11 psi and wait. If your impatient like me, try a half pint every few days to see how it's coming along.
