Question about PF jar holes..
    #5767698 - 06/19/06 11:29 AM (17 years, 7 months ago)

I just have a very quick question, would really appreciate some feedback. I'm a first time grower. I started out with my jar lids not tightened all the way, and covered with Tin Foil.. Then read somewhere that the foild impedes gas exchange, and is not really necessary.. I took it off, but after going through the shroomery gallery I noticed that just about every jar is foil-topped, so now I am having second thoughts as to my decision to let them "breathe." The jars are kept in a closed shoe box, which is wrapped in a clean towell.. Prior to incubation, the box, and the closet where it's being stored were hardcore lysolled... Is the possibility of getting contam that much greater now that I took off the foil? Should I reapply it? It's three days into incubation now.. I know it's not the most exciting of concerns, and really appreciate your taking your time to address it..

Thanks, Guys

After inoculating replacing the foil does not impede gas exchange unless you very tightly seal it which is very hard to do BTW. With lids cracked loose slightly you'll be fine. I like the foil as it does help stabilize (hold in) the moisture content of the jars in drier incubators. GL and Welcome bro

Ive always just left the 4 wholes in the jar uncovered and the jar top screwed on fairly normally tight and never have any trouble.

As you can see there are mant different answers to this question, but the most common thing is find a way you like to do it and do that way. I leave my foil off after innoc unless my jars look on the dry side. Then I piut it back on.

Always leave the foil on it is what is preventing contams from falling down on your substrate. In sterile technique it is very important to always keep things covered with foil unless they are sealed some other way.

There is no dispute or differing opinions on this. If you want to seal your jars some other way, go ahead. But any open container needs to be covered with something and foil is what is usually used because it's easy to use, cheap, it's easy to take off and put back on, and it sterilizes very well.

couldn't he put two coffee filters over the tops if the only worry is about contams falling in?

Coffee filters aren't going to stop most contams. Just try filtering some dark spore solution and see how easily things will slip through a filter like that. Tyvek works, but why wast all that time cutting it and putting it on when you can just use foil? You have to use foil anyway to keep water out of your jars while PCing, so why would you waste it?

As long as you have a contam. barrier, why would you bother with foil on the lid? Seems like overkill to me, but to each his (or her) own.

This is true, I myself like the benefits of using foil and there are a few but to the average grower they can omit it.

Thanks guys... Foil went back on yesterday. Couldn't hurt, I guess.. Plus a couple of the jars looked a bit on the dry side.. Wish me luck in my endeavors.. Hopefully soon I'll grace you all with some nice pictures!

He didn't say anything about any barrier. If he's doing it the normal way then the foil is the only barrier to contams falling directly down his holes. Maybe he's taped or sealed his holes somehow, but probably not.

Micropore tape, bandaids, blah. Just use the foil, it's better and saves money.
