Oysters on wheat straw

Preparing for my first attempt on edibles.
I have access to wheat straw as a main substrate constituent. I have clean petris of Pleurotus eryngii and Pleurotus ostreatus both of which I understand are wood lovers. I have experience with wood lovers, that said..
Anybody recommend a wheat straw based substrate recipe and prep procedure?
I understand straw can be used in place of woodchips/shavings however straw would produce less fruit. Is this a correct assumption?
Anything else I should consider only having experience with Cubensis?

About to start my own oyster grow soon, i am just going to do as per RR: wash the straw in soapy water, pasteurize with lime. then layer straw, then grains, straw, grains, until bags are full. Then wrap some wire around the top to close
Let them colonize, and when 100% gonna throw them into my martha setup and cut some slits all around it for the oysters to grow out of.
Seems the simplest to me

Ya gotta make grain spawn to inoculate the straw with. Not sure if you were talking about going straight from petris to straw or not? I like using wild bird seed. Rye grain is good, too.
Use a 1:5 inoculation ratio of grain spawn to straw and that tends to be enough nutrients for me to get similar yields from sawdust and straw bags. I pasteurize the straw at 150 for 1 hour (core substrate temp, not water temp). I don't wash the straw first. Remove straw, let cool in open air on a clean surface, add a baby handful of gypsum to each 1.5 gallon ish bag of straw, mix in your grain spawn, and pack into bags. Use a row of nail gun nails to puncture the bag for air exchange. When it starts to pin, use a razor blade to cut a couple X's in the bag for it to fruit out of.

Forgot about RRs snippet on straw. Im going to do a grow log for some guidance from the more experienced guys. Good luck on your grow, I doubt my martha will be ready by then. I'd like to compare results and tek.

Just transfered from agar to my PC'd grain.
Do you use soap? I'd like to skip soap, I am trying to get the family to reduce their environmental foot print. Would be hypocritical for my to grow on organic straw using recycled plastic etc. then use soap myself.

I do not use soap. I use hot water to pasteurize. You can use the water bath twice, then you need fresh water. you can use the straw "tea" as a weed killer. i dump it in the driveway to keep those pesky goat heads away

No, chopped wheat straw can be used as a wood chip substitute and has been shown to increase yields in shiitake grows.

Oysters grow better on sawdust than on straight wheat straw, however mixing the two should yield good results. I will be using this method with my oyster and shiitake grows in the future.

Yes both can grow on straw but hardwood sawdust is far better. I would recommend mixing the two together, the straw will help in the spawn run the same way woodchips do but is far cheaper and easier to find.

The link provided is just the abstract, enough info to get the point across. I have the complete study in pof but am unable to post, hope that helps.
