I've been using jars from Midwest for a few projects now, and I have absolutely no complaints. I've not had a single contamination problem, even once. The customer service is amazing as well. One of my orders had a damaged jar (shipping problem, not their fault) and they offered to replace my shipment or give me some store credit. I would highly recommend MWGK to everyone

Ive had the pleasure of using both the substrate jars and spawn bags and cant say enough great company overall!!!!

Who needs more drama in their lives now ? These eliminate what I consider the messiest complicted part of the whole process. I appreciate the quality and convenience and will be ordering again.

I have NEVER had a jar go bad. Awesome fast growth. Every time.

These are the best jars to get hands down, I’ve shopped all over and come back consistently because of the quality. They always arrive pretty quick as far as shipping goes. They back there product 100% if you have an issue, I’ve only had 1, it was taken care of immediately. Colonization goes quick because of there recipe which is key. Love this company for all things myco!
