Temporary double casing layer
    #12285108 - 03/27/10 08:44 PM (13 years, 10 months ago)

Experienced growers - what do you think about this:
With a temporary double casing layer i mean that the top layer could be twice (or more) the normal thickness, through most of the incubation time, and when it's time you remove the excess casing material with a fork. The thickness of the bottom casing layer can probably be adjusted so that it can be used as an indicator to when to remove the excess casing material. One would ofcourse have to be carefull not to harm the myc, or compacting the casing when scraping away the excess top layer.

Advantages:
1 - you could mist directly on to the casing and use larger amounts of water, without any fear of closing the cracks in the casing material.
2 - thicker casings gives bigger water reservoirs, which in turn mean less frequent misting.
3 - the top layer which have been exposed to contam is removed, thus lowering contam rates.

    I'm going to bed now, but in the morning i'll be checking if i have any disciples! The ones following other tecs will be burnt on the stake!  >8D

A water reservoir is only one function of a casing layer.  The more important one is creation of a mini-climate at the substrate/casing interface that's conducive to fruiting.  Over watering because the casing is thicker is counterproductive because you destroy that mini-climate.  Remember, loss of moisture from the substrate is a major pinning trigger.  A thick casing prevents loss of moisture.

In addition, there's little to be gained from casing cubensis, if that's what you're growing.  Many experienced growers have done side by side tests of identical substrates, some cased and others not, and the results were roughly the same either way.  That's why I suggest fruiting uncased bulk substrates.  If your substrate is plain grains, you'll need to case, but I wouldn't go over 1" at most.  Thicker casings inhibit fruiting, and scraping a casing is always going to cause damage. Mycelium is only one cell in thickness and can't be seen.  You only see it when it gets very thick.

Ok? I thought one of the main purposes of the casing layer was to prevent the substrate from drying out... (Confused) I guess your only talking about a light drying out, but could you elaborate on that? I'm currently in the pinning stage so any tips other than the standard temp/rh/fae would be greatly appreciated. Think i have to read up on this subject again and start to take more notes this time. Anybody know of a good thread is more than welcome to add a link to it here. The searchfunction is good, but it can be a bit hard to find good info on very specific subjects. People use different words, or write it in more general threads etc... You end up reading through a bunch of unnecessary material. A categorized index would be great, but impossible to make with posts covering lots of different areas... Think i have to make my own indexed guide (covering all aspects of growing) from bits and pieces of what i can find. Anyone done this already and willing to share???

Misting
is done in order to restore the lost moisture from the substrate, not casing:wink:

Evaporation from the moisture is -as said- a major pinning trigger. The water that evaporates sooner or later has to be replaced in some way (misting/dunking).

A good start are the sub forums of the cultivation forums. Lots of useful information in there.

I agree with the sub forums, theyre a hallucinogenic gold mine.

Ok. So i'd guess it works by a similar mechanism as when they pin when they have used/eaten up all the nutes in the substrate then. Thanks alot! "Now-or-never pinning strategies" seems to work good. Nute cycling, temp cycling, and humidity/moisture cycling tells them that they are out of nutes, or that a winter or dry season is coming, so if they are going to pin, they better pin fast, while still having the nutes, temp, or humidity needed for pinning and fruiting... And thanks for the link. My internet-reader breaks down when i click the normal link, but this link worked fine! I only have internet on my phone. It's a pain in the ass, but its free just for me! For some reason i've been able to use it for over 2months now without money on the phone! Its normally pretty expensive for one without a job.
