I got these to supplement the 12 that came with the Ultimate Grow Kit. They're exactly as described. Very easy to use, and they appear to be working very well. Lots of quick, healthy growth.

First timer here, great success. 12/12 reached 100% inoculation.

I ordered these for my 2nd grow after purchasing a kit. They're all colonized again and growing nicely. No contamination.

I have had excellent experiences with these jars. Mycelium growth took off in all of them, and I have not had any contamination.



My second time ordering 1/2 pint jars, 5 of the 6 arrived broken. They had been packaged well in several layers of bubble wrap, but I think the postal service handled the box poorly. I contacted Midwest Grow Kits, and they sent replacements for all the jars right away! Amazing customer service.

Have made several orders. And I've been happy with the product and shipping time. Thank you!!
