So I'm starting my first grow and everything has gone semi-smoothly. I have 36 quart jars loaded with wbs and I've been PCing all day for 60 minutes each batch. I am following doc's wbs tek and it says to pc for 60 minutes but now I'm reading 90 minutes is much safer. I'm definitely going to do the rest of my jars for 90 but will the rest of the jars cooked for 60 be okay? Would it be okay to re-cook them for another 30 or should I do another 90? Thanks in advance, I've been a lurker on here ever since I started to get interested in growing and I've only put off making an account cause any questions I have I can already find the answer to on these boards!

Grains should get sterilized for at least 90 minutes, not 60.
I would say just re-sterlize them for the full 90 minutes....can't possibly do that much damage...

Okay, that's what I'll do then. What a waste of a morning! Thanks for the fast response though.

Some people use 60 minutes and are fine. overall success rates go up when you PC for 90 minutes at 15 psi.
It also depends on the size of the jars you are using. My pressure cooker is only 5 litres so i can only fit 5 400ml jars at a time. I could probably get away with 60 minutes due to the size of my jars, but i do 90 minutes anyway.
With quart jars id probably want to go 90 minutes

You could leave one of your 60min jars out, could be useful to see if it contaminates. Even if it didn't tho, I wouldn't trust a 60min PC cycle with quart jars.
