    The entire ordering experience was super convenient and efficient. I appreciate that as a busy working person! I have used these substrate jars before and experienced fantastic growth with a high quality end product. The easy to follow instructions are invaluable also. Highly recommend these jars for ease of use + quality yield.

    I have never one time had contamination during the colonization phase while using these jars. Before when I tried to make my own jars I would always loose at least a few jars. Its so worth it. I also seem to get more mushrooms from using these jars vs making my own. Thank you guys!

    THE REAL DEAL

    I recently ordered another dozen of these half pint pre sterilized substrate jars.
    Not only did this item arrive within just days of my order but as a long-standing customer of MidWest and of THIS product I could not ask for a more reliable company or reliable product. I can’t fathom the saving of time AND effort using this item represents, but as Inoculation Times run a month or more, it’s nice to know all that time isn’t wasted. I look at using these as MINIMIZING the variables.
    Since I began using these jars I’ve not had one fail. THAT is consistency.
    At first I was skeptical such an item could be so reliable without making them myself. Now I know it can be.
    Over a year ago I began my relationship here buying a complete 2 tub kit.
    It had everything including a dozen of these jars. And it couldn’t be easier.
    Worth mentioning is that I have NEVER received a broken or faulty jar.
    This and every other package was securely bubble wrapped and arrives intact. Every time.
    Whether I order a full Dozen or just 6.
    Ready to go. And for me? Totally beats making them myself.
    Thanx MidWest.
    Peace.
