Great product

I bought 18 quart jars and so far I've inoculated 12 and all have healthy mycelium growth, none have been contaminated. Definitely not going anywhere else for my grain jars.

Some of the BEST

I have been using out-grow to source grain jars since i started this hobby at the end of 2017 so 7 years now. Any time the jars came busted they sent a replacement no questions asked. I have always had successful growth with little to no contamination. i highly recommend for beginners and advanced hobbyists alike.
