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

Always trust this company and their products. Saw they have a larger 7.5lbs option than the original 5lbs. This substrate is always delivered fast and in good condition. Field capacity is on point and added nutrients improves colonization. Put my grains to to bulk and within 24 hours had vigorous growth and fast recovery.

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

The substrate Midwest offers is top of the line . Very high success rate perfect field compacity (or wetness) Very Important!

I wish I could do a commercial for these guys just a great company that will even answer questions over the phone. 😯 🍄

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