Casing Technique

#1332923 - 02/24/03 10:27 PM (21 years, 1 month ago)

Okay, being new to this, I am just running this by the people here on the board, is this how a proper PF TEK casing is supposed to look?

what the FAQ's are a little shady on is the amount of vermiculite that is added to the mix. I knwo that the BRF is only supposed to be filled to the bottom of the threads (or 1/2" from the top of the jar) but is the vermicultie supposed to be from the top of that layer all the way top the top of the jar touching the lid?

thanks in advance.

it dosen't usualy matter, but there are times in wich it can be better in the long run to leave a little room.

what times would this be? is this to allow for expansion? I can't imagine that the substrate would remain the same density or volume with the addition of a mycelium network growing through it.

this is for cases in wich the mycelium fails to colonize the bottom of the jar in reasonable time.
when this happens, if you flip the jar over, tap it onto a hard surface to make the cake inside the jar to drop down to the inside of the lid, there will be an area of air around the uncolonised protion, often helping it to finish.
note that this is only recomended in cases hwere it is required, as it allows outside air into contact with uncolonized substrate, opening it up to possible contamination.
[edit: ps. i'm glad to hear you are using filter disks, they help a lot.]

it dosen't make any difference at all that 90% of the time, but you'll not know in advance when that other 10% is going to be, so id say it's better safe than sorry.

[edit: nevermind that...}
the dead air would be on top of the vermiculite, not under it [remember grivity? heh.].

>but is the vermiculite supposed to be from the top of that layer all the way top the top of the jar touching the lid?
Yes, to the top.

And the "dead air" in your diagram, what is this supposed to be?
How can be there an air zone between vermiculite and the substrate??

The cake shrinks during the colonization.

And, this is not a casing.
It?s a vermiculite layer.

Other way around. If you were using verm as your casing material, you would use that to cover your colonized substrate. :smile:

Edit, you are correct. I didn't notice the top casing layer in your diagram.

so there ISN'T a layer on the bottom?

the page you sent me to specified a 3 cm (1") vermiculite layer on the bottom and then a 1.5cm (1/2") layer on the top.

is this not correct?

Loos about right, except:

- The bottom layer is optional, and there is no need for 3cm of it, 1cm is more than enough
- the pieces could be smaller than 6x6cm(more like 1-2 cm)
- there are better casing materials than vermiculite
