ALWAYS A great experience. I ordered the 12 pack substrate jars. They were shipped within hours of ordering and arrived quickly UPS mishandled the package and 5 jars broke in transit. I contacted Midwestgrowkits and they immediately immediately replaced the broken jars. Even though it was in no way their fault. That's customer service!

I’ve used these particular jars with 50+ grows and have had a 99% effective rate. Never have had an issue that wasn’t my fault. I highly recommend these for anyone getting into growing their own fruits/mushrooms.
