Casing Procedures
Methods for creating a non-nutritive, protective, moisture-providing top layer for substrates growing species that need this.

The casing layer serves 4 purpose
- Does a casing require a fruiting chamber?
The casing layer is what provides the moisture for the mycelium, but the humidity around the casing needs to be high, otherwise it will simply dry out.
- What is "overlay"?
Overlay is a term that refers to the condition which can occur to an overly colonized casing layer.
- What does it mean to patch a casing and what is it good for?
No Caption
- What different casing layer ingredients are there?
Peat (=Sphagnum Peat Moss) Unconsolidated soil material consisting largely of undecomposed, or only slightly decomposed, organic matter accumulated under conditions of excessive moisture.
- What do I do after applying the casing layer?
Once the casing has been created it should be left at colonization conditions to allow the mycelium to permeate the casing layer.
- Why is my casing pulling away from the sides?
Casings will oftentimes "shrink" during the course of colonization, and will often do so towards the end of a flush.
- How to apply an even casing layer?
An even casing depth is important to achieving maximum yield and performance from all cased substrates.
- Casing material pH and why it is important.
"pH", is a measure to describe the acidity of a medium.
- Stamets Casing Mixture
Another casing mixture recipe.
- The Importance of a Great Casing Yebo
A great document by ShroomGod discusses the various aspects of casing.
- How do I initiate pinning on a casing?
Once the mycelium has appeared in the valleys of the casing layer it's time to trigger primordia formation.
- Should I use a bottom casing Layer?
There is a very popular debate in the OMC (online mushroom community) about whether or not to add a bottom casing layer to a casing (usually a vermiculite or sometimes coir layer, notwithstanding what you used to case the top layer with).
- Apprentice Casing Tek
Tips and lessons to help you become a better caser.
- 60/40 Vermiculite and Coco Coir Casing Tek
An illustrated casing tek utilizing coco coir and vermiculite
- 50/50+ Casing Tek
Ryche Hawk's 50/50+ casing tek version 3.1
- When should I put the casing into the fruiting chamber?
Once the mycelium appears in the valleys of the casing layer, meaning you can see mycelium strands beginning to poke through the casing layer, but the surface of the casing is not yet colonized, you should initiate pinning.
- How moist should the casing mixture be?
The casing layer should me moist, but not wet.
- Sphagnum Moss Tek
A way to grow Cubensis utilizing sphagnum moss to provide moisture.
- Mini terrarium casing tek
A casing tek using colonized pf cakes and mini terrariums made of plastic cups and plastic bags.
- Oss/Oeric Casing Mixture
A recipe for a casing mixture which can be substituted into any casing method.
- suck it
Fill the colonized substrate in a opaque casing container, level it with a clean spoon or fork and spoon the casing material on the top of it as even as possible, without pressing it down.
- Can I use hydrated lime in my casing mixture?
You can, but you have to be very carefull how much you add.
- PF Casing Method
Another simple casing method.
- Easy Casing Method
Probably the simplest casing method for beginners to use.
