recycling Oyster Mycelium question

I have been growing and selling Oyster Mushrooms for the last year (mainly at farmers markets) thanks to a lot helpful info on this site. I grow on hanging straw logs and have a 10 x 6 fruiting room. I have only been doing 1st grows so I can sell weekly, unfortunately I just don't have room for a 2nd or 3rd flush. I also order my spawn from a company.
I had an idea today that I wanted to run by you guys. What do you think about breaking up my 1st flush straw logs and adding them to freshly pasteurized straw? I was just thinking that I am throwing out all that good mycelium to compost, you think it would be okay to try or do you think I would end up with serious contamination issues? I usually go through about 40lbs of spawn per month.

Try spawning that colonized straw to spent unpasteurized coffee grounds and/or cardboard.

You never want to use fruited substrate as spawn for new logs, you will get little yield and lots of contamination. Really all old logs are good for is compost or trying to give as a treat to cattle to eat as long as contam free. Mushroom compost goes for a good bit of cash or you make want to consider putting in a garden to make it useful. I recommend letting the logs compost inside the bags as the plastic makes for a greenhouse effect to heat things up.

Adaptation never creates a new species or trait, but rather the new species/trait always existed within the parent DNA until circumstances allowed it to be activated. For instance, every wolf has the DNA for poodles, but that DNA would never be revealed without man selectively breeding for it.

They need higher than ambient humidity unless you live in Seattle during the rainy season.
To Natasha, the logs can fruit again outdoors if you have space. In fact, the only place I fruit oyster straw logs is in the woods next to our creek. I can't grow them indoors any more due to spore allergy.
The spent straw substrates are also excellent animal feed, being up to 50% protein. RR
