Hmmm, I have a problem. I just ran out of CO2 and won't be able to get more til Monday. I posted another thread about carbonating for my jockey box and it was posted that I could carbonate for 3 weeks at 70F @35-40PSI...or I could prime with 1/3 priming sugar.

Will 19 days (keg on Monday) at 70F @40 PSI be enough to carbonate my kegs or should I just prime with sugar and KNOW that my kegs will be carbonated for a party I'm having on Sat, Sept. 15?

i've never carb'd at warmer temps.

however, if your party isn't for 3 weeks from today...why are you sweating it at all? go refill CO2 on Monday and put it back on gas.

otherwise, prime it and remember you'll need to discard the first couple of draws as it'll be full of yeast sediment from the priming.

I've read somewhere that if you prime kegs with Corn Sugar you only need to use half the usual amount and let if sit at room temp (same as for bottles) and it'll carb naturally.

Get more CO2 on mon. My kegs have never taken more than 7-10 days to carb, and I carb/serve at 12 PSI. High pressures are really only needed to force carbonate quickly.

Good Luck!

No, he needs the high pressure because it's carbonating at a warm temp. If you carb at serving temp (cold) then you can let it sit for a few days at the serving psi and it will force carb itself. There's an online calculator somewhere... Here's one:
