Pressure Cooker/Autoclaving Question...?
    #8036026 - 02/17/08 11:18 PM (15 years, 11 months ago)

Hello all. I am currently making a small batch of PESA using Alien's Substrate in a PF style, using 1 Pint Jars. I have cooked 6 jars worth and am fixing to Sterilize. I read somewhere 15 psi for 35 minutes. And I was just wondering, I had never really thought about it before but do ya'll time 35 minutes from the time you turn on the stove until you get up 15 psi, and then go for 10 minutes or so longer, before turning off, or you do you time 35 min. from when the needle reads 15 psi? It takes 10 minutes for the needle to even start moving... Thanks.

The sterilization time starts AFTER the pressure gets to 15psi.

Close the valve (or put on the weight)about 5 minutes after you start to see steam come out.
It blows all the dirty air out first and heats up the PC and jars more evenly.
and yes timing starts after you hit 15 psi.
