Growing mushrooms has been a hobby of mine for a little over a year now. Out of all the brands of gypsum (or any mushroom product really) this one seems to really value clean. The gypsum arrived in perfect condition, has instructions, and is noticeably better quality just by looking at it. I will continue to buy this brand, I am super satisfied.

Mixed feelings honestly. I purchased this for soil conditioning, but it looks like this type is mainly for growing mushrooms? Was not aware mushrooms needed gypsum! Company was helpful though and assured me it can be used for soil conditioning as well. Apparently it is the same, even BETTER they say! We will see. Good customer service though.

I have purchased this 2 times now and will be purchasing again. Good gypsum for the price, and it has come quick both times. The only other way I have bought gypsum is the big 50 pound bags, and the ones I bought here is way more convenient and seemingly better quality. Over all I am satisfied.

I originally bought this to grow mushrooms, and it worked great for that. I had a ton of left over, and added it to clay soil in my backyard, which I am planting vegetables in this spring. Great stuff all around and I recommend this gypsum for any reason.
