Casing layer

Here's another recipe that's been verified for the casing layer:
Note: This recipe is obviously for medium and large projects, so if you just need a little bit you can keep the rest for another time.
Mix the following items
A) 7.5 Liters of SPHAGNUM PEAT MOSS
B) 3.5 Liters of PROFFESIONAL GRADE VERMICULITE
C) 4 Liters of FINE SAND
D) 2 Liters of finely crushed OYSTER SHELL
I would throw in a little potting soil but apparently this recipe is better without it.
Note: You can get A B C at LOWES and you can get the oyster shell from www.mycosupply.com or perhaps locally at an animal feed supply store.
To prepare the casing layer mixture:
Add spring water and pasteurize in the oven (covered with tinfoil) at 150 degrees for an hour, perhaps less.
Let it cool completely (probably 24hrs)
Apply a very thin casing layer. Make sure it's even all over with no inconsistencies.
Keep the layer moist but not soaking. (Misting at least a couple times a day with a fine mist should be sufficient). Make sure it's not too wet or you'll stunt your mycelium from growing properly while inviting molds at the same time.
Additional Notes:
You can wait til the time your substrate is 90% colonized with mycelium before sprinkling your casing layer onto the top. However, if you want to do it immediately you may do so with the risk of overlay (IE when the mycelium grows ontop of the casing layer more than it should).
Additional Note:
A casing layer is ADDED for every flush. So after your first flush make sure you first remove your specimens and the bases of the stems that remain, then add your casing layer. Again, that's each time you finish harvesting a flush.
Additional Note:
If you have been growing sporeless mushrooms, the casing layer may prove to correct this. If you have been growing small specimens with hollow stems, the casing layer may also correct this. You should at least see a drastic improvement. The appearance of your crop is also more aesthetic when a casing layer is added that includes the peat moss mentioned above.
If this benefits your harvest please post about it and spread the word clearly.

I'm not sure what the sand does exactly. It was recommended in the book entitled "Magic Mushroom Grower's Guide" in their most ideal casing layer recipe.

Perhaps PH level?

Sand won't do anything for pH. It just helps airation in the mixture. Sand doesn't hold much moisture but it holds some and is pretty good at evaporating it, so I'd think the only reason to add it would be airation. The size between sand particles is relatively large compared with a cell, so when you think about it, it probably has about the same effect as gypsum.
