Micro pore tape filter material (What you need to know) 1

This thread is for the new guys that for whatever reason cannot purchase synthetic filter discs; tyvek envelopes or otherwise. Micro pore tape is readily available and will work for all your mycology uses (with proper application) .:Note:. When purchasing Micro pore tape, only buy the cloth type, avoid plastic and paper micro pore tape.
Rather then digging threw threads and having to determine who is right and who is wrong when arguing about the use of micro pore tape I figured I'd post a thread about the proper use of micro pore tape as a legit filter with 100% success.
The jar on the left has one of those screw on lids from a old spaghetti sauce jar, the jar on the right has a inverted lid with the band. (Keep this in mind)
You new guys can clearly see where I fucked up here.... What you see in the picture is a Gas exchange problem due to the double layer not releasing enough co2.
So, when preparing your jars when using micro pore tape, always ensure that the bands are left cracked and when using lids that screw on, they need to be left loose during the colonization period, once inoculated, loosen them and wrap micro pore tape between the lid and the jar like so.
And thats all the info one will ever need to know about using this stuff in place of other filter material.
I'll post pictures of the jar once it catches up with the rest.
And as always,

A trip to the post office for tyvek would be a better route for anyone new. A trip to wally world for a 3$ bag of polyfil would be even better.
I'll admit I've had more then one jar with just a strip of micro-pore over a hole as both the GE and noc port, but its stupid risky. I got lucky and had 3 LC's turn out fine with a strip of tape as the only barrier to contams, but I was mostly screwing around and was too new to realize how bad I could fuck up my future grows

Nonsense.
PO tyvek is poorly suited to mycology, far worse than micropore tape. Don't encourage stealing here, even if it was any good. RR

I was under the impression it was better then a soggy piece of tape, since it has served its purpose for myself and countless other shroomery members
Since it seems like you have something negative to say about every one of my posts I'll correct myself to say paint-suit/sleeve tyvek.
My local Walmart has both options for around 6$.
I personally like ez-felt. About 1$ for a sheet that will make 12 disks, and each disk lasts 3-4 trips through the pc before it gets too stiff

The tyvek suits here in Canada have been cutt with polyester, even the ones claiming to be 100% tyvek.
All major retailers stopped selling vermiculite/gypsum/wheat straw bundles etc
The government is not stupid.
In order for me to get ahold of stuff as simple as vermiculite I need to buy a 22kg from a hydroponics store.
I think the next thing they'll pull is coir from all the local reptile stores and replace it with something else.
But again, this is why I said "Whatever your situation may be"

I dont know man, it looks to me that you can get your vermiculite at home depot in a 9 litre bag for $7.99. As far as gypsum goes, you guys do have drywall up there in Canada ya? And if you cant get straw in Canada, then I am going into the straw business and moving to Canada.
Do you really think the government is going to remove these products fro store shelves because of the few people who use them for growing illegal mushrooms??? There are far too many people out there who use them for legal uses for the government to make stores stop selling it. I would think we would see something so stupid from the US government, not Canada. And there is no threat of losing these items here yet. I am about 100% sure that if they pull coir from the shelves, reptile owners are going to go ballistic on them for doing something so stupid.

This is why the smart people use aluminum foil and not tin.

Believe it or not a tin-foil hat actually increases susceptibility to the very frequencies that those of a conspiracy theorist mind-set believe are the cause of their problems!!
Sweet irony, (now that’s a fucking conspiracy!!)

Derail the thread much?
Its not a conspiracy.... and micro pore tape is just fine for home cultivation.
I get the joke about tinfoil hats but they may be altering aluminem foil for its (Al) properties....it is used for manufacturing mdma.
So, maybe you're right

+1 for sheets of Felt. I paid 1.40 for 2, 9"x12" sheets of 'FriendlyFelt' and can make about 9, 90mm 'SFDs', and each one can be cut into about 8 smaller circles to fit 1/4" holes on jar lids, so 1 sheet (70 cents) can make 72 discs (for 72 jars).
And yes, they can survive the PC.

Two days after loosening the lids to allow proper gas exchange....
(Lighting had to be upped in the pic to show the growth)
Compared to
I wish I had better quality pictures demonstrating micro pore tape as a legit filter and the importance of gas exchange but these will have to do.
If you didn't know, now you do.

i used to cut out quarter sized pieces of ez felt and got 88 to a sheet, with room left at the bottom which bugged me, now i cut squares and get like 96 or something to a sheet, use the whole sheet no waste!

Envelope tyvek is a poor gas exchange filtering material choice. Not all tyvek envelopes are created equally. Meaning, some can take a run through the sterilizer while others can't. Either way, envelope tyvek will need to be replaced after each use. Use a proper gas exchange filtering material such as synthetic filter disks. Polyfil is a better gas exchange filtering material than envelope tyvek, micropore tape, and painters cover-all tyvek. Medical grade tyvek is acceptable, because it can be sterilized an unlimited amount of times.

I don't mind using the tyvek only once. The ones I have are Dupont Tyvek and pretty damn strong. I have however been leaning more towards the poly fill because it can be used as an injection port. I'm assuming from what I've read I just bore a nickel sized hole in the top and then stuff it. Would you suggest a loose or tight stuff. Why does that sound so dirty?
