2 holes?
    #23369986 - 06/22/16 01:32 PM (7 years, 7 months ago)

I have been looking into using self healing ports for my quart grain jars with synthetic filter discs. I've read a lot of people having the injection port and one hole for gas exchange. However isn't it true that there should be two holes; one for air going in and one for air going out?

Why couldn't one hole facilitate the in and the out exactly?  Filter discs work in both directions..  It's not like there's tubes going in the holes with a one way air flow.

I was told that the gas can't go in and out the hole at the same time by a buddy of mine, but I didn't find any supporting claims within the forums

Take this buddy of yours, tie him to your bumper, and take a sunday drive until you don't hear anymore screaming.

The hole is by and large there to prevent a vacuum forming.  Air will never need to go in and out at the same time.  It either forms a vacuum and pulls air in slowly, or produces a positive pressure and leaks out some air through the filter.  Physically, you can't have air going in and out of the same very small container without perfectly balancing the two to prevent a positive or negative pressure. 

Seems like a very complicated view of simple physics.

lol  thanks guys, that makes sense.  I'll stick with the one hole. Also what's your guys take on the size of injector ports? I've seen some 13mm and others 20mm. Is one size better than the other?

I don't use injector ports since I feel they're a contam vector but when I did I always just did a 1/4 inch hole covered with a dab of silicone.

I will research the silicone method, especially if that's less likely to contaminate

I noticed there are plastic lids with a gas exchange hole and injection port already assembled; I may go that route...

One hole is sufficient cause you want a gas exchange, not a fresh air exchange. The mushrooms create
C02 which is continually being produced. There is not really any air coming
in the jar, just c02 leaving the jar.

The myc creates a slight
pressure in the jar which allows a constant escape of air, like if you were
to put a filter on the end of a tube and lightly blow into it. Air would
still exit the tube regardless of air entering the tube through the filter
because of the force of you blowing through it. Mushrooms produce gas which exits through
the filter and more gas is produced right behind it pushing it out. The hole is there so co2 cant build up in the jar.

You can use unmodified lids, no ships, no filter... just crack the lid for GE. Lots of pleople are doing this without issue. Plastic lids for your mason jars with screw-on lid or pp5 bottles with screw-on lid. Shroomies' like it all nice 'n simple :awesomenod:

1 premade lid cost $1.50 to $2.25 multiply by however many you need, let's say 10 = $15-$23 for just 10 premade lids!

OR

8 pack of plastic lids at Walmart $3 x4pcks= $12
RTV Silicon $5
4x SFDs (trace a US quarter 8x on 1 SFD and cut them out) $4

That's 32 lids for $21

That is what they mean when they say you pay a magnitude more for someone else to do the work.
It could cost you $75 for 30 premade lids OR $21 to make them yourself.

Well it's both. The vacuum doesnt form in the pc because of the hole
and during colonization co2 can escape.

yeah well, my bad. drugs reduce attention span.

But really I was just asking for you to elaborate. Inocuole I trust your experience but you didn't explained the context of your comments. I guess I'm just wanted more information since you are such a great resource on this forum.

I'm a noob after all.

:lol: it's all good man sorry for coming off like a dick!

Filter serves many purposes, but the main one is to filter air no matter
which way it is going! In the pc a vacuum forms so you want filtered air
when you break the vacuum, in colonization you dont want particles to make
their way into the jar while it sits even if air is mostly flowing out of
the jar.

As stated before you can even do unmodified lids with no filter or hole.
Just needs a little more attention.

Well Nate answered my quest in less then twenty words and that is no wall of text. Thanks, I really do appreciate your help. I understand us noob are frustrating and you probably over explain to people who don't listen and get burnt out. That's not me, just a stoner moment. Thanks again. I respect your feedback.
