PF jar breathing questions
    #3777836 - 02/14/05 11:04 AM (12 years, 4 months ago)

So here's my set up. I have a tub in tub in the closet with 1 or 2 dozen half pint pf( brf verm.) jars going to be in it. After reviewing many teks/question posts/logs I have a few conflicting ideas on what should be done about the top of the jars.

1. Put holes in the lid that comes with the jars and cover with perforated tape.
2. Put holes in the lid that comes with the jars and do not cover with tape.
3. Cover the top of the jar with tinfoil and puncture with syringe to inoculate, leaving open holes.
4. Cover the top of the jar with tinfoil and puncture with syringe to inoculate, then cover with more tinfoil.

And if using tinfoil on the top what do you do while steaming pressure cooking?

1. Leave a single layer of tinfoil on the top of the jar. then steam/pc. then inoculate
2. In addition to the piece of tinfoil, add another piece of tinfoil crumpled up below the edges of original tinfoil to keep out moisture.

I'm interested in tinfoil because i seem to see (maybe its just the posts I'm hitting on by chance) some of the more experienced growers using tinfoil and it seems, overall, possibly easier to handle.

Last question I have regards the use of a cover for a tub in tub. I see a lot of people recommend a blanket to maintain the right temps for the jars. If the jars have to pull their air through the blanket wouldn't they pull any contams the blanket might have through with the air? It just seems less than sterile to me.

I understand I asked a lot of questions here. I tried too be as clear and coherent as possible. Appreciate any help I can get on these questions. Have a wonderful week =)

If you are using lids, I prefer the lid + a layer of tinfoil loosely atop of it.

If you are using foil only, use according to http://www.fungifun.org/pf/pf_en.htm

The incubator doesn't have to be real sterile. The dry verm layer at the top of the jars serves the purpose of keeping bad stuff out of your substrate. As long as you leave the lids on, with needleholes open, then they can get the air exchange they need and the dry verm will keep contams out. You may still lose a couple, but most if not all of your jars will make it if you sterilize properly and are careful when inoculating.


--------------------
Excerpt from one of my textbooks:
Therefore, between a then and its matching else, there cannot be an if statement without an else. Statements must be distinguished between those that are matched and those that are unmatched, where unmatched statements are else-less ifs and all other statements are matched.
I wonder if that would make more sense if I was tripping when I read it.

What I do:
Puncture holes in lid for inoculation, cover with tinfoil for sterilisation, cool with tinfoil on, take off foil when cool and immediately inoculate. Leave foil off and holes uncovered for duration of tek.

Works for me. I very rarely get a contaminated jar.

thanks guys, i appreciate you all, thanks to anno to for responding to my pm, thats great. So i think one of my problems with the jars i knocked up on the first is they werent getting ANY air exchange. I removed the tape (i know, dumb of me to have it on) today, any chance these might pick up and go ahead and colonize now? if not no biggy I have a huge bag of vermiculite and another syringe =)

i use 2 layers of tinfoil. I found alot less growth when i use the lids w/ 4 holes in it.

Also i recommend flipping the jars over, better air exchange.

In terms of gas exchange and all, if i put the jars completely sealed under my bed, which means under my matress since my bed is not open from the sides, will that be bad for them?

Make it 50/50 and see if there is a difference.
