TYVEK LIDS
    #6368021 - 12/13/06 09:20 PM (17 years, 2 months ago)

Having become concerned that my jars aren't breathing enough, I've prepared a couple using tyvek ONLY, no metal lid with holes, just the screw-on band. I simply inoculated wherever I wanted to and covered the small hole with breathable tape.

Recently I read someone saying that regular tyvek can sometimes be too thick to allow enough gas exchange so I figured that widening the available surface might help in this regard.

But then, if it's such a great idea, I probably would have read more about it by now.

Does anybody have experience or an opinion on this? My only real concern is too much breathability drying the jars out too quickly. Obviously I will find out soon whether I'm an idiot or not, but would still like to hear from others on the subject.

You have a good idea, but I thin that moisture is a factor that might hurt you. I don't think tyvek wicks, but it could allow for some moisture exchange with so much exposed tyvek (exposed to your jars contents I mean) Also for the all around physical strength of the jar. (stacking and shaking and such)

here is my way that works well as hell for me.

This is the top of a ring/tyvek/lid setup for a quart jar. The red is just a nice drop of RTV HIGH TEMP sealant, this gives me a breech point in the tyvek that self seals.


Here is the underside of same setup, notice the 1/2 in hole for GX (gas exchange) you can make as many as big as you want with this setup, they are all covered by the tyvek.


So just make holes in your metal lid, put on your lid/tyvek/ring, and drop a good bit of RTV for a innoc. point. When shooting up just go through the RTV (and the TYVEK too) into one of the GX holes you made. The little space between the lid and tyvek make plenty enough room for GX.

:smile:

Not only will they dry out that way, they'll cause premature pinning by providing air exchange, as opposed to just gas exchange. You need to at least tape over 90% of the tyvek with duct or shipping tape.

I've found that a 3/8" hole covered in tyvek can loose a lot of moisture in dry conditions. I've read other people suggest a 1/4" hole is optimal.

RTV sealant does make good injection ports.



The clothespin, when dripping wet, can be used to shape the sealant.

The only problem I have with this design is that I don't reuse the ports since they're attached to the tyvek, and making them isn't much fun. So I'm sitting here thinking and I come up with this.



Reusable sealant port on a 3/8" hole and 1/4" gas exchange, Covered in Tyvek. Tyvek gets alcohol swab before innoculating, covered with a piece of scotch tape afterwards.

this is how i do my lids, basically like you describe.  no metal lid.

piece of tyvek over the jar, ring over that.  PC, then inoculate where i feel like as well (usually just poke the needle right in the middle, point it at an angle, and spin the jar in a circle as i innoc so inoculate runs down the sides all around).  quickly cover the hole with a piece of micropore tape and swab over it with some rubbing alcohol to make sure its clean.

now on to the "too much gas exchange" and "moisture problems" :smile:  simple solution.  i take a piece of duct tape, and cover up about 90% of the lid with it.



its so simple.  on one particular occasion i made my seeds too wet... so i didn't put the duct tape on until 3-4 days later... worked like a charm, i used the "it will dry out!!" thing to my advantage in that case to recover from a goof-up.  i let them dry out some, things stabilized nice, laid down my tape, finished the colonization run, came out perfect. :smile:  sooo... doing it this way kind of has a built-in protection that lets you "recover" from over-moisture.  a neat benefit.

these lids are a bit ghetto i suppose... but hey, it works... and again... sooo damn simple. :smile:

I inoculated 49 qts of WBS successfully with no contams By drilling a 1/4 hole in lid using the RTV hight temp sealent as a innoc port and drilled four 1/16 holes for gas exchange put tyvek over the lid that goes down and screw on lid cut away excess tyvek and cover with alum foil while PC'n might have a little water on top of tyvek after PC'n just wipe it off quickly ass soon as you remove the jars and you'll be fine and ready to go just cover hole in tyvek fron inoculation with a alchol soaked pc of spore tape and wah lah..

To each it's own but, IMO polyfil lids are the best. You can inoculate the jars right in the open air and the lids can be re-used several times also. Until the material is starting to decay. I used Tyvek for some time and then discovered polyfil. I haven't looked back since. So much easier and just as effective.

Thank you all so much for your input. I guess I will duct tape over most of the lids in my experiment then. I had some slow jars earlier and thought that maybe my gas exchange wasn't enough.

I shall therefore continue with a couple of holes in the lid next time, covered with tyvek. Obviously my problems lie elsewhere, given the community concensus on this issue.

I do like creamcorn's idea of adjusting coverage or time to match differently hydrated jars in an emergency.

As one becomes more adept, I'm sure this is hardly an issue.

THANKS!!! I learn more all the time with all of your terrific assistance.

It always amazes me how many different people have such different opinions,I cant even explain how much I hate polyfill for jars,hey different strokes for different folks as they say,If it works for you and you have success with it I say go for it  :thumbup:

Why not reuse Tyvek? I actually have use RTV to GLUE a perfect size circle of TYVEK to my lids. The RTV holds it well and adds a little cushion when the ring is screwed down. (helps seal up the edges). I just grab a lid and throw it on. Simple. Durable and long lasting. This way you don't have to make sure your lid hole is covered with RTV, or whatever. I just love this way. But to each his own.

So I think this cat is successfully skinned...

... and deboned, nutered, de-clawed and fed.

i hate tyvek soo much i used it all different ways with ok results and some contam but now i use poly fill and i will never use anything again...

i use metal lids with vacunater tops as ports and 1/4 hole with poly fill taped over it

100% my way from now on.

well i dont like the rust after drilling the metal lids but i will get plastic ones.

>>>>Why not reuse Tyvek?

I've used the same tyvek twice with no problems, but after the second PC, the tyvek is visibly warped. This causes a potential opening for contams since warped tyvek is an indication the fibers are moving around.

I am curious though, how many times you've reused tyvek with success.

If you have injection ports to use on lids.

A simple method is to drill a 1/4 to 5/16th hole in the lid.

Cut a small square of tyvek (3/4 X 3/4 inch), place it over the hole.

Then, tape it down with a piece of 1X1 inch Micropore tape.

This gives you good gas exchange provision.
That is permanent on the outside of the lid.

Injection is done THROUGH the port.

I have PC'ed lids like that 15 or so times, no problemo.

I now use all plastic lids, with a port & micron filter patch.
