I've cultivated Pan cyan on hay alone. It worked good, I got about 2.5 flushes.
They didn't want to fruit directly on cased rye, so I pasteurized hay, spawned,
incubated, and only 1 week after I cased I had a nice amount of Pan cyan. It should
also work with straw. Actually I'm going to grow some on straw next week. I'm right now
incubating the spawn.
You really need only a very thin casing layer...

I've seen that Pan cyan is very sensible to high humidity, much more than Psi cub.
I've had some containers in which the fruits didn't want to develope normally. The
fruits were very thin and didn't sporulate. So watch the humidity...

I maybe use, in comparisson to other people, high rates of spawn, but I also grow in a smaller scale...

I use about 0.5 to 1 L of rye spawn for 2 to 3 L of end substrate. This means I use about 25 % vol of the end moist substrate. I'm sorry that I don't have the density for moist straw/hay.
The colonizing velocity of Pan cyan I've measured lies between 0.2 to 0.4 L/d (Liters of end substrate per day), when it is incubated at 27 C. The velocity for Psi cub
is about the same at 28 C. The colonizing velocity should not depend on the volume you are colonizing, if you use constant relative amounts of spawn. But I don't have consice data on that.
One more thing to this velocities: I select the cultures, i.e. no multispore inoculation but a pure agar culture. There is a big difference in colonizing velocities, because using agar you don't have an offset as a consequence of the time the spores would need to germinate.

I sterilize the straw/hay for 30min at 121 C. It is for me much more convenient and energy saving to sterilize for 30 min than to pasteurize for 45min to 1 hour. And I've had good experience with this method.

Thanks man. that?s the kind of information that is realy usefull. That, and some good analyses from a genuine paradigm of mushroom cultivation.
I think the hay is a good ingredient by the way. Going to start some experiments with fermenting straw with hay during a couple of days before pasturizing it. Could be interesting.

Good luck,
