to air is human ..... To answer my question is divine!
    #14275035 - 04/11/11 09:32 PM (12 years, 10 months ago)

In my understanding polyfill provides a distraction for other contams to get lost in, due to it's complicated multilayered structure.  But, pontentially can provide pass through if given the correct conditions: Movement, temperature/humidity changes, Random Acts of God (doesn't apply if you are atheist).

Tyvek filters allow greater blockage of contams due to its high density and design.  This allows less frequent air exchange, due to natural O2 and C02 osmosis air will be exchanged. 

If my understanding of the two is correct, and they are they are both solid arguments, and methods.  What is your opinion?

I live in a house which I cannot control mold or natural pathogens (Old ass dirty house).  Don't judge, at least I'm honest.:tongue2:  I think that I would need the assurace of having a filter medium which acts as a actual barrier in my less than ideal environment.  What is the question you say?

I have ordered Tyvek Discs and I am planning on cutting them to smaller circular size.  If the tyvke discs are more dense and can only exchange the air due to its surface area (I think I heard that through the Rabbit hole), what size circular discs should I cut my lids to?  Taking into account that I  am planning invitro sclerotia and will be harvesting at 4-6 months.

This thread was moved from Advanced Mycology.

Reason:
Off topic in advanced mycology.

Tyvek isn't better than polyfill.  Synthetic filter disks are the cream of the crop.  You can buy them already cut to both narrow and wide mouth mason jar sizes.

For the application you mentioned, tyvek is the way to go....
You are trying to provide gas exchange, not Fresh air exchange.
I would just screw the ring of the jar back on over a piece of tyvek cut to size..... Just make sure the ring gets tightly screwed on and that the tyvek covers the top of the jar entirely.

Another helful hint.... Keep the place your incubating these at a high humidity... since sclerotia potentially take months.
You don't want the jars drying out prematurely, that would negatively affect your sclerotia yeilds.

No. No, man. Shit, no man.  I believe you'd get your ass kicked sayin' somethin' like that man.

Thanks for your feed back guy!  Good tip about about the sclerotia storage, I didn't think about controlling my "incubating" environment and how to control it.  10 Points to you!

I was also thinking.  Couldn't you adjust the gas exchange by taping up a portion of the tyvek thus reducing the air flow.  Potentially you could adjust the gas/humidity with just some tape over the tykek.  Do you think that the tape adhesive could permanently block the tyvek even after removal?  I am thinking painters tape (less adhesives)

I have been reading for years at the shroomery.  The definition of a forum according to Websters: 

a : the marketplace or public place of an ancient Roman city forming the center of judicial and public business
b : a public meeting place for open discussion c : a medium (as a newspaper or online service) of open discussion or expression of ideas

I gotta say that after 24 hours, over 25 views, and only two responses (thanks RR and Shroomie_Glen), less than %15 participation from viewers, this a poor example of a forum.  I am sorry to say that.  I have enough knowledge to answer my own questions, but I like having a forum in which good/bad ideas can be shared, different points of view are expressed and radical thinking can be supported.  I am not speaking because of my own post, but my view in the overall website trend.

Oh, if you have an opinion about what I said... you should probably post it on a a forum; or not.

You're judging us because you are too lazy to use the search feature?
It's been debated and discussed at length.
Synthetic discs > polyfil > tyvek > micropore.

Next question? :rolleyes:

and you can get free tyvek at your local post office, just ask for the priority mail envelopes (they usually have them sitting out on the counter)

Please don't steal tyvek. Plus, it's just not very good tyvek. And even good tyvek isn't a very good filter.

Those are badass envelopes for mailing things though. :thumbup:

Come on Doc read between the lines.  ( I mean it with the great respect I have for you)  I am not judging I am merely saying we should all comment more... Not you... you make everyone else look bad  30,049 posts! 

Now for the judging part.  I have been using the search function and have been reading a lot.  But because I didn't state this I suppose I am lazy,sounds like judgment to me:omgawesome:

I posted because I had a specific question regarding the surface area of tyvek and how it affects gas exchange.  Because I feel this is a topic that hasn't really been addressed. 

Trust me if I were to judge, with on only have 129 posts I would call myself more of a hypocrite than anything else.

I think I may have come up with a new lid design that may allow a flexible control in humidity and gas exchange that can adjust to environmental variables.  There is real value in forums, in my opinion though if the only value is through the search function, than this Internet Data Base Rocks!!!

Those views almost certainly include people who aren't logged in or who don't even have an account.  Its not like all those people could have replied.  Additionally, many people likely don't know.  Its honestly better to have people who don't know keeping quiet- like me for instance. Forums where people just spout off are filled with useless 'information'.  Its better that people recognize their limitations.

And I wouldn't admire Doc_T's post count too much- most of those posts are just him telling a new person they're on his ignore list.

What is a Tyvek disc? Do you mean like a Tyvek sleeve for compact discs? Just listen to the trusted cultivators and buy synthetic filter discs. Just do it. Do it.

And yes, I have to partially agree, Doc_T isn't very nurturing to us nubile miscreants.

Yeah, that was the whole point!  10 points for the name. 

I know those were some sexy lids!  My question was  You made a small hole on the lid, yet made a much bigger circle for the synthetic disk to be glued on the lid.  Was there a reason? is it a surface area thing? 

True I agree, most of Docs are:  Copy...Paste "Use the search function"  I am kidding he is pretty helpful, and people do under utilize the search.

I made the disk larger than the hole to make sure I didn't get RTV on the underside of the filter that is exposed to the interior of the jar. Thus, clogging the filter more.
