    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.

    I originally ordered the ultimate mushroom growing & incubator kit and have been using it for a couple years now. Love it! I've since ordered some add-ones such as the UV light sterilizer and mold isolation polymer and have ordered substrate jars five times. Have been pleased with everything I've received. Shipping has been prompt and everything arrived in good condition with easy-to-understand instructions.
