Curing in Mason Jars with Tyvek?

[daihashi]

I have started another hobby that uses Tyvek. Tyvek is a plastic material that you can find everywhere. One of the most common places is Fedex. Their envelopes are made out of Tyvek. Tyvek is also a Vapor barrier used in houses and I think you can even get suits for painting or something made out of tyvek.

Anyway Tyvek allows for gas exchange while at the same time keeping out contaminants that would allow conditions for mold or other things to spawn. From what I understand Tyvek does not allow for fresh air exchange but will outgas things such as CO2 and whatever gas is made when the plants are breaking down chlorophyll. I am using this for my other hobby specifically for these properties.


Would it be beneficial to sterilize the jars; place the buds (properly dried) in the jar, and then place a tyvek filter over the mason jar with the ring and not the lid?

My thought is that this would allow the Jars to outgas whatever builds up in the jar; prevents fresh air from getting inside which will keep the buds at the proper moisture level and it will be a deterrent to mold. The best part of this; is that in theory, you would never have to open the jars unless you had some condensation building up on the glass. Due to the lack of fresh air coming into the jars you would also be helping to create an anaerobic environment to help break down chloryphyll faster/better.

Again this is all in theory. Does anyone have any experience with this or any input on the use of Tyvek in curing?

I don't have the slightest idea...but, it's good to see you back...daihashi...:thumbsup:

lol.. I wish you had the slightest idea. And I'm back but definitely not an active member. The situation revolving around the forums from when I left previously has still left a bad taste in my mouth but I'm coming around.

Will probably never do another grow log again but it doesn't mean I can't talk and exchange ideas right? :hippy:

Been trying to find more information on Tyvek

Tyvek - Wikipedia, the free encyclopedia

Tyvek (pronounced /taɪˈvɛk/) is a brand of flashspun high-density polyethylene fibers, a synthetic material; the name is a registered trademark of DuPont. The material is very strong; it is difficult to tear but can easily be cut with scissors or any other sharp object. Water vapor can pass through Tyvek (highly breathable), but not liquid water, so the material lends itself to a variety of applications: medical packaging, envelopes, car covers, air and water intrusion barriers (housewrap) under house siding, labels, wristbands, mycology, and graphics. Tyvek is sometimes erroneously referred to as "Tyvex."

I'm not sure how much water vapor passes through; reason being is that in addition to tyveks ability to create a sterile environment... I also use it to maintain high humidity levels; which would lead me to believe that it *shouldnt* lose too much moisture but was hoping that someone with a little more insight than me could help.

I'll definitely set aside a jar and try this if I can't get an answer.

i dont think its a good idea,i were a dupont tyvek suit for 12 hours a day and based on personal experience i would think if it did anything it would only cause problems if it would do anything beneficial i dubtful

Hi Daihashi,

I've used Tyvek for an addition to a house; it is suppose to let moist air escape out of any cracks of a house so there is no moisture or condensation trapped in the insulation. But at the same time not allow air infiltration to the building. Suppose to be breathable in one direction only, thats why the directions say to put it on the house logo side out.

I think you have a brilliant idea there! (sorry to disagree with you disrupt86)

It should allow for the escaping of of the outgasses....the only difference I see is this; when we burp the jars periodically we are not just releasing the outgasses but allowing fresh air back into the jar. I don't know how important that is tho, it certainly warrants an experiment.

Thanks for sharing that idea and I'm also glad to see you back around.

I think the Tyvek idea is a good one, makes a lot more sense, than a lot of 'ideas' I see here ... I wonder, though, if it might allow drying to occur TOO quickly ... it takes time for the chlorophyll to break down into gas, so I wonder if that may impede the process ... but, I'm no expert, and I smoke a LOT of marijuana, so, be careful with my advice :jointsmile:

What are your concerns?

From a human point of view they are very very hot. They don't breath as well as I'd like them to; but luckily for me the jars are not people.

What exactly do you think would cause problems? Tyvek by nature was designed to be a gas exchanger as well as a water barrier. What is your experience with tyvek aside from wearing a suit? How well do you actually understand it and in what applications have you used it aside from wearing a suit.

I'm not looking to wear it; I'm looking for a more efficient way to allow the jars gas exchange without letting excess moisture out.

I will most likely do a side by side comparison of 2 jelly jars. I'll put bud in both of them and cover one with the metal band and tyvek, and then the other I'll cure the old fashioned way and report back. I've asked this question on several boards now and no one seems to know.

Tyvek is pretty popular for use among mycologists for several of the properties I've listed in this thread.

Anyone else with input or followups?

Well of course it makes sense; I said it didn't I? lol jkjk.. but I know what you mean about 'ideas'. When I was active on this board I read a million "ideas" that I just rolled my eyes at and a handful that I actually gave a nod to.

I'm really concerned about 1 of 2 things and they are really just 2 sides of the same coin:

1. It will dry too fast (although seeing as how it maintains moistures in these jars I'm inoculating; I don't think this will be an issue)

2. It won't allow for enough gas exchange and will allow condensation to build up. (if this happens this renders tyvek useless for me but I can still save that jar by just reverting to the traditional method.

looks like an experiment is in order. I have a harvest coming up in 4 weeks so we will see.
