Can straw be steam sterilized?

Or would you have to PC a mixture of BRF and straw?

Has anyone tried replacing vermiculite in the PF tek with straw?

Actually, it's very easy to isolate a super producing sclerotia strain.

Follow the strain isolation technique on Let's Grow Mushrooms, and then select sectors early which are brown in color.  By the second or third transfer, you'll see stones developing, and this is only about 1 month after the original swipe of spores on agar.

Now, take each stone and move it to a new dish.  Soon, the mycelium will grow out and you'll see fresh stones developing, and if they're good strains, the sclerotia is forming long before the mycelium reaches the edge of the plate.  Pick strains which form four or five stones within two weeks and use these for your grain masters.

Usually, straw is used for bulk growing (as you know, you're not exactly a noob, are ya :smile: ), and pasteurized. I suppose it could also be sterilized, possibly even steam sterilized, though I suspect that PCing it is a safer way sterilize it.

I haven't tried replacing verm with straw in PF tek, but I think it could work, although I don't see the pros of straw vs. verm in this case very clearly. Perhaps there's a reason you want to try this?

I can see the benefits. Straw actually contains nutrients, unlike verm. If you can get the water content right, and if the jars don't dry out it might work. Interesting idea.

I have steamed it with success. And this was timothy hay and wheat straw, both worked fine steamed. I don't know about using it as a replacement for vermiculite, sounds like a good idea to me though.
