Force Carbing a 3 gallon keg - different or the same?

Is a different psi recommended for force carbing a 3 gallon keg? I’m afraid that if I carb at 35 psi for 24 hours it will get too carbonated. Maybe 20-25 and then check it? It’s the white house honey porter. Any ideas?

Thanks!

You will be fine.

However you do it, it will carbonate in 60% of the time as a 5 gallon keg.
