masking tape breathable?

ok so im doing pftek. i put masking tape over the nail holes on my lid, but flipped the lids over before PCing because the masking tape was on the non-rubber coated side. so now the masking tape is on the inside of my jars, and im wondering if it will prevent air exchange. i didnt even inoculate through the holes because they were too small for the needle, i just lifted the lids slightly in the glove box to inject. should i poke the holes through with a sterile needle? it seems risky

Having the masking tape on the inside can cause contamination due to it getting wet and such so it's much more preferable to have it on the outside...and you can buy micropore tape at most any pharmacy or drug store for like $7 bucks (yeah, it's expensive, but at what cost?) Haha.

I used masking tape before (that's the light brown color tape right?). I didn't experience any problems w/it though I put it on the outside of my jars. It peeled off rather easily after pressure cooking (as in it'd just fall off sometimes). Didn't matter though.

if you are using the pftek, you should have a verm barrier which blocks contams and after inoculation you dont want those holes covered with masking tape or foil because you will get no gas exchange. masking tape isnt breathable. if you want breathable tape get "nexcare gentile paper tape" in medical supplys at a drugstore. it will say "micropore tape" on it somewhere really small.

Its best not to have it at all, with pf jars the vermiculite barrier is your filter, no tape needed

I've had issues locating micropore tape. I ended up buying 3Ms medical tape. No idea if it's breathable but it seems to be working

You should be good using no tape at all if your doing pf tek. I tried with some on and some off and the ones without the tape did better.

Flame sterilising a pin red hot then poking through will be fine. Just remember to do it within a glovebox.
