This grain jar makes inoculation super easy and more controllable. Highly recommend!

Great product, sterile

Jars always work for me. Great instructional material and quality products. Working to advance the art of mushroom growing :)

I’ve used the jars for a few years now and love them. Shipping is quick and come packed very carefully. Colonization is fast. Love it.

I really like the new size of these jars. They arrived quickly in discrete packaging. I've ordered these before and the colonization time is amazing. Getting them out of the jar is extremely difficult so a rubber mallet might be needed to get them out in one piece.
