ha! Hell no, let it grow! Love it. It's growing. About the size of a golf ball now. From the side it looks like fans of pink oysters, but from the top it is just solid. Insane how dense this freak of nature is.
I am all about the recycled material. I have tons of cardboard that I could use, and even though it's not going to save me much money by using cardboard as opposed to straw or hardwood pellets, it would be great to repurpose the material. I'm holding off on introducing any other substrates for the time being since I am experimenting with different environments and methods to regulate my FAE and Humidity. Not to mention my Calcium Hydroxide pasteurization experimentation with my Wheat straw in my blue oyster bags. My spreadsheets are singing sweet songs of successes and failures, which is a song I love to learn.
After arathu mentioned that he found some growth in his compost pile from the "failed" straw log, I decided to check where I dumped my "failed" pink mushroom bags. Pink Oyster mushies popping up everywhere between pieces of straw. Looks like I'm growing inside and outside now.
Here's a pic of the pink turd in my tray. Looking pretty funky, but I'm proud that it's my turd.
