I hate tyvek, and why
    #4292436 - 06/13/05 07:31 PM (12 years, 1 month ago)

Although I have used tyvek with some success for popcorn grain spawn and other various substrates, due to this recent experience I will never use it again. I recently found jars with mold growing from THE OUTSIDE IN. That's right. Tyvek has been established as a suitable growing medium for not only black pin mold but trich as well. I know it wasn't coming from the inside of the jars, because I had some fully colonized jars in the incubator that had been chillin there for a week, with no contamination. As soon as the contam was intoduced into the incubator it started growing on the tyvek on top of the fully colonized jars. As I said before, when used properly tyvek can be an effective barrier against contamination in limited circumstance, but it is mediocre at best so watch out for it! I'm switching to polyfill.

I have had this happen also in the last month also. I thought it was because the tyvek got wet in the pc so I'm trying again. I'll probably switch if it happens again. The green was on the outside growing on the tyvek and eventually made it thru at some point!

Probably wrong tyvek or you've used it more than once.

Same goes for polyfil...If it gets lots of water introduced into it or by it...Or Mold near it...BLAM.

My guess is you've had mold or you're house isn't up to par. Not saying it's dirty, i'm talking about the ecosystem outside.

I couldn't tell that there was but I cleaned mine out and trying again. I also used another layer of aluminum foil in the pc but it still seems the tyvek got alittle wet but not like before.

That happened to me, but it was cuz my Tyvek had paper in it! You have to make sure you're using 100% Tyvek, esp. if you got it from the Post Office!

lol good link backupwards. That would explain it. For my friend, it was a combination of that and his incubator being sloppy. He cleaned the shit out of it with alcohol, so it should be all good. Put in the work get the products.
