Making the holes to the jars
    #2971769 - 08/06/04 01:32 PM (12 years, 11 months ago)

I was just wondering.Could I fill up my substrate jars,tighten the lids,pressure cook,let cool overnight and then poke the lids and innocculate?

The other day I prepared one jar (still waiting on the spore syringe) with 1/2 cup Verm 1/4 cup BRF and a 1/4 cup of water mixing till my arm was tired.I pressure cooked at 10 PSI for one to one and a half hours (btw I covered the lids with foil).Problem is I opened it today and the dry verm top layer is a little moist.Is this normal?

The problem with poking the holes after pcing is that the pressure causes a vacuum within a tightly sealed jar, so that when you go to poke the holes air from outside (along with whatever contams are there) get sucked into the jar.

if u have a pressure cooker then you should be fine. just make your holes and put tape over them. then p.c. then remove tape inoculate and cover back up. u really dont have to worry too much about molds an shit getting in those tiny tiny holes. just make sure u spray the area real good first

Completely normal.

Make the holes BEFORE you pressure cook.

I dont think they will explode..canning jars are made to be sealed tight in a pressure cooker. Also the pressure increases on the outside so if anything they would implode, but they wont do that either.

It makes absolutely no sense to try to make holes afterwards :wink: Do the holes first! Save yourself and do it right the first time! :wink: :laugh: GL

doing the holes first will also kill any contams that what you use to poke the holes may put onto and into the jar.

Do you generally have an issue with 'dirrections'?

I pressure cooked my jars then let the cooker cool for an hour. I then took them out and put them cardboard box to let them cool over night. They are covered with tinfoil and i already poked the holes beforehand. Is there no risk of contamination until i take off the tinfoil and inoculate? I'm going to spray mad Lysol in the air and around the area before i do it.

The foil has nothing to do with contamination. The foil is to prevent the water dripping from the lid of the pressure cooker from seeping into your jars. The filter covering or under your holes is what provides protection from contaminants.

It's best not to remove hot jars from the pressure cooker. Removing the jars while hot can cause them to evaporate their moisture, thus leaving them too dry.
