Can I use peat and calcium carbonate for a casing mixture without vermiculite?

The substrate is rye berries. If I can do this, how do I know how much water to add to the casing?

You guys seriously need to shop somewhere besides walmart.  If those bastards can't find it in china or from a supplier without a union, they won't stock it.  Every nursery I've been into for the last 40 years has vermiculite.

Peat can be used as a casing material without vermiculite, but it's better with it.  However, you'll get better performance spawning your colonized rye to a bulk substrate, and then fruiting it uncased.

I've had good success with peat alone and with verm, with no pH balancing whatsoever. Some casings gave me 4-5 flushes and contamed by the bottom(ie: the casing layer wasn't the culprit)! Just make sure to remove the wooden bits!

I also lowered pH of peat with baking soda in the past and it worked as well (make sure you add little at a time and check pH with papers/digi meter).

Finaly, RR is right, you will have better results if you spawn to bulk. I personally use 80/20 coir+coffee(not leeched) with a pinch of blood and bone meal. Uncased works great but you need to maintain higher rH for steady results.
