Great product, great price.
I am very happy with my purchase. I use this to feed my mushrooms, edible mushrooms, and I am very happy with the results. I have mini fruiting mushrooms, which came from being fed on this gypsum and I’m very happy with my purchase.

Works well for homebrewing beer
High quality product, at a better price per ounce than home brewing suppliers. I've used it for making a couple of batches of beer, and it does what it is supposed to do. It dissolved quickly, and doesn't seem to contain any impurities. Some other brands are ground sheetrock, and suited only for gardening. I looked at it under 20X magnification and it looks identical to the food grade stuff I've been buying for much more money.

Blossom end rot cure
Worked like a charm to cure my blossom end rot in my zucchini. The directions on the cover were helpful for all different uses. I’m glad it’s food grade safe so I can use the extra for all kinds of things like canning or brewing.

Great potting soil additive for vegetable gardens.
I added this gypsum powder to my tomato garden and it seemed to help them remain healthy throughout the summer. It also seemed to work good with my cucumbers. The snails don't like it so it helps keep them away as well.

Works perfectly!
Good value. Really effective for making tofu. Goes a long way. The tofu I made with this tasted 100 percent better than store bought tofu.
