Great product! Everything is amazing about it. The value, the functionality, plant growth, moisture retention. I can't tell you enough if you use it for Mass use. It's very well and if you can find other uses for it, I'm definitely for the size and quantity you're getting. It's unmatchable plus it's trustworthy brand

Definitely recommend great product will be buying more

I bought this to make silken tofu and it worked perfect! The seal on the bag is really good and I don’t have to worry about it leaking.

As expected

Works fine

The product came on time and delivery was prompt. The packaging was resealable which was very important to me. It was definitely ultra fine which made it very easy to mix in hot water to dissolve for use in my CVG substrate. I am totally satisfied with my purchase and will probably be reordering when needed. I use approximately one cup of gypsum with 1250 G of coco coir and 2 qts of vermiculite with 8 qts of water for great field conditions.

Perfect for tofu pudding. I brew 3/4 gallon of soy milk every three days (from two cups of soy bean). To make tofu pudding, I heat two cups of home made soy milk in a microwave to 95C. I mixed 4 grams of gypsum, 4 grams of corn starch, and 1.5 table spoon of cold water in a separate bowl (stir well). Pour hot soy milk (95C) into bowl contains gyspum, corn starch, and water . Voila, perfect and quick hot tofu pudding in less than five minutes.

Really Great
