Great product! I received my order in only 3 day, I easily tracked the package the whole way. 4 days after inoculation I wa seeing mycelium all over the jar!

These jars are really great and failproof anyone can do it, I highly recommend!

As the title states, I've had no losses to contamination so far from these jars compared to bags. They offer enough grains to fully colonize a substrate and I feel they've been great at their job. Shipping was great and well packaged. Can't beat it for the price

Best customer support ever in any thing I've ever bought from tires to toilet paper you won't find more helpful people. If you call during business hours you get a person right away.

These jars are incredibly fast colonizing! Best money can buy!

The name of this product is “Super Fast Colonizing” five grain jar and my experience so far is just that. I had some Pennie’s Envy liquid culture that I produced from a couple of fully colonized jars. The syringes weren’t ‘loaded’ like purchased liquid cultures, but you would think they were given how quickly these jars are colonizing so far. I’m barely a week in and they’re almost 50% done already.



This is why I stopped busting my butt making my own grain jars. It’s so much easier and much more reliable to order these. Highly recommended, and I’ll be ordering many more in the future.
