5.00 stars, based on 27 reviews
Our 32oz organic rye jars are a quick and easy way to start your next bulk grow. Rye berries are extremely high in nitrogen and release their nutrients slowly. This is why people have been using rye for over 50 years to grow mushrooms of all types!...

Great Jars

These worked pretty amazing! Super easy inoculation (Just make sure you inject enough spores I did 5cc's) Full colonization from PE spores in 19 days! Could not be happier!

I thought about making a my own PC grain but was intimidating by the start up cost and process in general. I was so excited when I saw these rye grain jars offered by Midwest grow kits. They shipped fast and have been great quality. I will definitely be ordering again.

This company fixed the issue and I will continue to do business with them. I have never had a issue with them. 1 in 2 yrs isn't bad. I already reordered also. Love the substrate jars.
