    Our 8oz Ultimate substrate jars are the quite possibly the best on the net! We have worked for over 15 years looking for perfection! We finally found it! We have combined special organic brown rice flour with vermiculite, mineral water, Liquid worm castings and Bee pollen to create the Ultimate mushroom growing jars! Each jar has four pre-drilled holes in the lid and a top dry layer of vermiculite for added protection. We have customers who have been using our jars for over 10 years simply because no other jars will out-perform ours! With the Fastest possible colonization times, the largest possible mushrooms no other jars will perform like these! We use Ball 100% Glass Canning jars! No plastic substitutes like others sell!

    We hand make every jar the morning your kit ships so your jars are the freshest possible! They are pressure sterilized in our Autoclave for 120 minutes.

    Because I choose not to make my own substrate and casing, I value a good and consistent quality. I have never been let down in any of the products I've purchased from here. I highly recommend!
