The jars are incredibly easy to use together with any of the growing kits. There's really not much else to say. They work just as advertised. The jars can be used again and again once purchased. Personally I use a few as drinking glasses as a reminder of good growing times.

I've ordered these jars several times and have never had any issues. Works perfectly.

Great product with fast delivery. 100% success rate with 0 contamination. For sure better then I could do on my own.

The substrate provided in these jars is perfect for colonizing and growing mushrooms. Never a bad jar in my experiences
