Exactly. It can?t be blown through. But you can suck some air in, try it. This should be the right stuff.

Any new results or findings? I?ve been using tyvek at regular basis since then and I must say I?m very pleased with the results.

Anno, do you re-use the tyvek? I have tried tyvek envelopes, the only stuff I can find (unless I buy a 100m roll). The envelopes were hard to find. Anyway, I had a few jars with bacterial contam. I soaked the tyvek in a water/bleach solution, and re-used it with good results. The one thing I have found with the paper tyvek is, if you hold it up to the light, where its been on the jar it seems thinner. I don't know if this is where the jar has reached temperatures more than the tyvek can handle, so beware when re-using! It works well, no complaints here
Good luck

I thought I posted a reply to this thread earlier before I left work, but it's not here. hmm.
I had previously ordered that Tyvek Homewrap demo kit. I think that stuff doesn't allow enough air exchange. My testing left me with some gooey junk that had originally been brf and finch seed. I chucked it all. The documentation that came with it talks about how good the stuff is at keeping the cold air out of your house, so I think it's not inteded to provide air exchange.
I just picked up some fed ex mailing envelopes which appear to be the same type of material as the USPS envelopes. I'll let you know my results of this test. Going to use EQ on BRF (no finch seed).
appreciatively,

>Anno, do you re-use the tyvek?
Yes. But As you said, it wears out after several uses. I?d say I use it like 5 times, then I replace it.

Have any of you ever tried good ol' 97cent coffee filters from your local grocery store? I'm sure they're not as good as filter discs that I'm seeing a lot of or tyvek but they promote air exchange and contam filtration. In fact, I think I got the idea of using coffee filters from the shroomery a few years back. *shrug*

I had used my PC and heated the jars for about an hour.
Do you think contams were responsible?

>Do you think contams were responsible?
Well, contaminanants were responsible for sure. The question is, where did they come from. Were they in grain and survived the sterilisation? Di they came in with inoculant or air? Or did the Tyvek filters leak?
I don?t know.
In my experience with tyvek filters I?ve only had positive experience so far, tested on around 50 jars.

Hey Anno, I'm thinkin' of using Tyvek with my next experiment. I'm planning on using a varient of the PF tek. If I were to use the Ramsys' (sp?) seal with the Tyvek, would I put the Tyvek on the top or the bottom of the lid? If I put it on the top I'd have to tape the holes right?
thanks

There is not really a need to use tyvek when you do PF cakes. With PF cakes the classic vermiculite seal(not the ramsey seal) has proven best, IMO.
