No reason to use only one layer, mp tape is cheap so use 4 layers if you can.

2 layers is better than one, and while it does tend to work, I would personally advise against micropore altogether.

There is also an image somewhere of micropore under a microscope with large enough holes and tears for spores to fit through.

SFDs for the win. Fast, effective, simple and yet quite cheap.

That was a good read (11 years old...) but still interesting. Quick googling led me to find this on 3Ms micropore surgical tape:

Also, they have provided some additional info on bacteria breach of the tape itself:

I think going 3-4 layers (criss-crossing as you layer) should provide a substantial filter barrier. covering with Alum Foil prior to popping it in the PC, you should be good. This will allow the to properly dry, and should provide adequate protection from bacteria.
Any thoughts?

i used nothing but MP for years. it "worked good". my contam rates were low but definitely not zero. it would get gross after a few cycles and was a sticky pain in the ass to change. because the down side is sticky grains would always glue themselves into my FAE hole. and i never felt confident putting my jars in the fridge lest the temp swing pulled mold spores through it
like i said it works fine in a pinch. i wouldnt recommend it to someone who wants to get serious tho

Hmm, has anyone attempted to tape a layer on the INSIDE of the lid? This would prevent the grains from making contact.
I wasnt planning on re-using the tape, either pull it off after finishing a jar, and reapply fresh, or just get new lids.
I know it would take some additional prep time per jar, but you could use something like goof off (or some other product that is not as strong) on the exposed underside of the tape to get the adhesive off(some weak acid as per 3M). Delicate work I would imagine as you dont want to dissolve the acid too much, just enough, probably using a stiff q-tip with the tiniest amount.
Thanks for the heads up on the grains sticking, if its unwise to tape to the underside of the lid, then will be cautious when shaking my master jar up!

After reading this string I decided to try it. I got 2 bags contam with cobweb mold so clearly im screwing it up. I have questions.
1) how long are you soaking and if you go so long as to fermentation is this a problem?
2) how big are the bags you are filling?
3) how long do you run them in the pc?

So I thought I had WBS dialed but it turns out the stuff I can get cheap locally has these little pellets in it. If you have ever seen chicken feed, that is what it is basically. It's ground up something, I'm guessing seeds, but they probably add some sort of something to it. So it would be ground up and mixed with water and some adhesive agent and extruded like spaghetti, dried and broken up in little pieces. It seems to dissolve in 10 or 15 minutes so if you let it soak for a while and rinsed it through a strainer then it would get rid of all the mush I think and just continued the soak. It also has cracked corn in it.
Anything wrong with using this anybody can see?
They also have canary seed that I'm going to throw some agar wedges into and see how that does but I'm really wondering about the WBS I can get here.

Canary seed it is, tons of it around and cheap too. Seems pretty similar to millet and that is seemingly hard to find here as well.
Any tips on the soak and or boil time Baked?

ive just done my first experiment with WBS injected with a spore syringe (made by myself). i just left it soaking in a big pan over night then bought it up to the boil and dumped it into a strainer then onto a flat sheet till it went cold - worked fine.
