Quick question on Tyvek Envelopes

It's been a while since the last time I've posted on these forums and I've got an interesting inquiry. I have finally found some Tyvek mailing envelopes. however, they have a "weather seal". I was just wondering if this layer is breathable, considering everyone uses them and i have yet to see someone remove it. and if not, how do i remove this layer when i purchase these envelopes.
thanks in advance.

I would bet the weather seal doesn't completely block air from passing - just liquid. I could be wrong though...
The tyvec I use doesn't say anything about a weather seal, but it is water resistant - meaning if something gets spilt on it, the water runs off. If you put water in the envelope and squeeze, the water slowly seeps through.
If you already have the envelopes, seal it up with as much air as possible and see if you can squeeze it out.

that's what i'm thinking. however, it can also simply be that they do not let air pass through and everyone is using them as a placebo effect. that is why i am bringing up the question. From my experience, jars without any form of FAE (not completely full with grain) colonize fine without it, which is probably do to the negative space in the jar providing more than enough fresh air for full colonization of the grain.

Agreed that if there's enough air in the jar to begin with it could fully colonize. However, the co2 that's not let out could be slowing growth making it take longer to fully colonize - just a theory though.

yea nenl you're right just take a jar of grain knock it up then seal it completely see what happens

this is in no way an attack of any form (sometimes people get the wrong vibes). but i just finished saying that I've knocked up jars without any breathing holes and they have fully colonized just fine. I'm gonna take a wild guess and say it might be gene specific on CO2 production and results can vary. Just like I've seen someone on this forum in the past that made a mono tub without any holes or any transparent window for light... and still got a full tub of cubes. Sometimes some strains thrive better than others in varying conditions, that's why I'm implying that maybe the weather-proof tyvek is producing a placebo effect for many.

I nocced up some grains 2 weeks ago with some "weather seal" tyvek, and it seems to be colonizing--slowly, but still colonizing. I'd say it'll work, but I'm not sure if the slow colonization time is related to the tyvek envelopes.

and THAT my friend, is what i am trying to uncover. thanks for the post man. I guess no one has noticed that their tyvek envelopes from staples are weather proofed. which they are. all of them.

buy filter discs which are designed for this purpose. tyvek filters are not the best choice. filter discs can be reused hundreds if not thousannds of times and withstand bleach cleaning. tyvek is a 1 use only deal.
you need gas exchange otherwise co2 can build up to toxic levels and slow/stall growth. the key work here is gas exchange and not fresh air.
and before someone chimes in saying they are expensive there not, considering how many times they can be reused and are sized to fit your jars.
also keep the metal disc with 4 holes punched for gas exchange. using just the filter will provide too much air.
