Micropore Tape and Heat

Using PF but this time found some micropore tape. Last time I used duct tape and it was sticky and nasty after my sterilization. So when I bought this stuff, I saw how thin and transparent it was. Are you telling me this tape is going to be able to handle the heat during the steam process?
Stealing another question too while I'm at it. Being early in the canning season, I could only find 1/2 pint regular jars, rather than the wide-mouth tapered. For the terrarium I will be using, it stands taller than wide, so I was thinking I could utilize the space more effectively. However, I will sacrifice the security of having a wide base after my birth. Should I be concerened about these jars/cakes? Thanks!

You don't need any tape on your holes before pcing. Doing the pf tek you really never need any tape. You have the dry verm layer to protect against contaminates. Just cover with foil before pcing and your good. If you want to use the tape then put it on after inoculating.
As for the jars. They will be ok, just take a bit longer to colonize.

thanks for tape advice. but question, why would a taller substrate cake with less girth take longer to colonize? i can still shop for the wide mouth classic jars but it seemed like a taller rather than wider surface area would grab more humidity in the chamber....but thats different I guess.

Been a long time since I've done cakes. I used those jars and later used 1 cup pyrex dishes, shorter and wider. In the taller jars it took longer for the myc to reach the bottom. The colonization of the bottom was then rather slow. The shorter jars it would tend to colonize the sides and bottom at the same time.
They work though

Tape over the holes is an added insurance policy. It prevents contaminants that land on the dry verm barrier from being pushed into the rice flour below by your inoculation needle.
3M micropore tape will be OK in the pressure cooker. It becomes hard to remove, but you don't need to remove it. Inject through the tape and then just leave it there. Use a fresh piece over the mess on your next batch.
Use wide mouth jars. You'll have problems with the regular mouth jars if you use them, and you'll be the millionth person to post in a few weeks asking why your jars are not colonized yet. RR

Well I looked everywhere and it must just be too early for the widemouths??? So I'm giving the normal 1/2 pints a shot. They are cooking right now. what I did to compensate for any colonization issues I might have is I did not fill these jars as much as usual. So they will be small but I will have more of them. Maybe too small... maybe I should case these. Well I got a few weeks to decide. Any advice?

I think it would be impossible to take the cakes out of standard jars. So you'll have to grow shrooms directly in jars. Also you can use plastic polypropylene food containers (they have number 5 in recycling triangle) instead on glass jars. They will work good. Their melting temperature is about 165 Celsius so they'll survive in pc. I'm using them because in my area I wasn't able to find any wide mouth jar. And plastic containers are cheaper and have a lot of sizes and shapes.
