I have purchased this item several times and I am very happy with the price, quality and shipping.
Had been spending money trying to get the right home made substrate mixture but would end up with no mycellium growth or jars of molds. The Ultimate Substrate jars from Midwest were awesome and everything as advertised. All 12 jars produced some serious colonization. It was the ideal mixture and I will definitely be a returning customer.
This product is awesome , all but one of my jars are healthy and thriving ! The one odd ball out I’m sure was my own fault. And then you get to keep the jars to make our own after! Great deal. Thanks guys.
Price was great, Jars are great, Shipping took a long time though.
