    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 ordered the substrate jars because it's my first time growing and I was unsure about making my own jars. I am very pleased. I lost a few jars to contamination (assuming this is on me as it was my first time inoculating), but I also have eight jars growing great looking mycelium right now! These jars are a good way to get started when you are new to this.

    Grew mushrooms back in the 1970s from spore prints. Now with syringes and your jars or bags it takes half the time. Fast shipping great product.

    Excellent product and well packaged . Quality is excellent and delivery flawless. If you’re looking for a high quality no nonsense way to fruit then this is definitely a go to product. I have no interest in autoclaving and sterilizing since introduced to this product . customer service is superb.

    Cons:
    I have ordered these Jars five times and will continue to use them. I never had the means to make my own jars and these have always worked great. Every time I have order from this company they get me quality product, quickly. The packaging is discrete and package where the jars have never broken and I have never had a problem with contamination. I would love it if they start making Jars half this size but will always continue to turn to MWG for all my future needs. The guide they send with them every time is also super helpful for newbies.
