Calcium Sulfate Dihydrate - Gypsum - CaSO4*2H2O - 1 Pound

Whenever I notice my tomato or pepper plants are starting to get blossom end rot I apply this and it clears up. Very happy with this product, just ordered another since I finally ran out.

Craft project

Great additive to your dirt… i’ve been using this exact product for 3 years and love it. Never disappoints.

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.

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.

When you order gypsum what can go wrong. Was as described.

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.

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.

yeah, a pound of gypsum. great product!

We started using this product and since we have no more bloom rot on our tomatoes. Wow!

seems fine

Ordered the wrong product.. realized that wasn’t good to make my tofu The Explaining should be a bit more clear!

Had some calcium deficiencies with a couple of my raised beds and this was the right stuff. Worked as expected.
