The substrate mixed with the spawn bag easily with minimal mess.

I’ve been cultivating mushrooms for years and i love mid west bulk casing. I always have happy healthy mushrooms 🍄

Used one spawn bag and only one bag of this and I am on my 4th flush so far!

Have used this casing mix for several grows, just noticed it came in this larger size, which is perfect for my two small tubs.

Looks great and is packaged great. I have gotten to use it yet because my spawn bags are not there yet by it I will try u to update my review when I do. Honestly, I r never had an by issue with Midwest so I don't expect to now.
