    Our 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.

    Super Simple to Use

    Cons:
    I am basing this review on the 12 jars we received with our kit. It is pretty obvious we are happy with them, since we ordered 12 more jars! We are new to this "hobby" and have found the jars to be very easy to use. Our single issue that we have is that we end up with a lot of jars. We are not ready to start making our own and until we do, we are going to be collecting these puppies. We would love to be able to send them back (and would pay to do so) so that they can be used again, if possible. Perhaps there is a solid reason that this can't be done and we are missing it. Anyway, awesome jars! We will ABSOLUTELY order them again!
