Damned I want to case...   -   Stevoi812

I notice most on this forum are using the PF Tek or some more advanced adaptations, and not many seem to be using Bulk Spawn Casing Teks (or perhaps I just haven't read enough threads). Either way, I have a question regarding my casing layer. I am using a Rye Grain Spawn as Substrate and a peat moss/vermiculite/lime casing layer mixture (10/5/2 cups proportionally).

First, in this application, which is preferable, coarse or fine Vermiculite, (and why?) and the second is in regards to the Lime. I know that Dolomitic lime (Dolomite) contains material detrimental to mycelial growth, but what about Hydrated lime (powdered form) with calcium hydroxide added to it? Is calcium hydroxide good, bad or neutral towards mycelium? And for what reasons, if any?

I linked Archive areas into your post for additional information. On the Verm I prefer a coarse Verm on double-end cased Cakes. It breaths better on cakes.

In cased beds I like medium verm. It mixes more evenly with peat and has better moisture holding qualities in this application. IMO

Calcium hydroxide works, use about 1/3 the amount as if you were using powdered rock or CaCO3. Calcium hydroxide is strong.
