97% Pure Gypsum Powder, 1 lb – High Solubility Calcium Sulfate Dihydrate for Soil, Gardens, Lawns, and Mushroom Substrate

What can I say, it’s gypsum powder. Works great

I recently started using gypsum powder in my garden, and I'm pretty impressed. It's way cheaper than other soil amendments I've tried. I noticed a real difference in my plants' growth, especially my tomatoes. They seem healthier and more productive. The powder is easy to mix into the soil, and it doesn't have a strong smell. Plus, it's a natural product, so I feel good about using it. I'd definitely recommend giving it a try if you're looking to improve your soil.

Fast service, lab quality

Its gypsum. Nothing wrong with it! Good price.

Good

I’m using gypsum to break up clay soil, and it takes more than a few weeks to see results. Asking for a review at this time is inappropriate.

I bought this for my potted avocado trees that I had to bring in for the winter. The leaves were falling off and browning and I read that this is a great soil amendment. Now, my avocados are flowering and the leaves are all growing back and flourishing.

I have had good results.
