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

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.

Food grade gypsum I use in my CVG mixture. Nice size bag, excellent for water retention in mycology. Easy to use, and pest free

It is pricey and most people wouldn't buy and use like I do. If I am going to go to all the work to eliminate heavy metal and other stuff. Why use mined gypsum.

Works well

GREAT!

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.

Works well for my gardening needs. Great price, will definitely be back fore more. This is my second time purchasing and I'll keep coming back.

Works great with NO CONTAMINATION! Will buy again !
