All natural and a dream of a product for organic gardeners, vegetarians and health conscious people trying to rid their environment of chemicals and poisons. Most of us that use DE think it is a miracle. But, I have decided not to list the benefits and uses of Food Grade DE because of government related fees I would incur associated with my labeling it for some of the uses. Most of us who are health conscious and/or organic gardeners and foodies know about and use DE – me, too. There are so many uses for this product that I have to leave it to you to search the web for information. I package it in a 1-gallon ziplock bag, like you use at home. It holds about 10-ounces of DE. That is alot. I also offer it in a refillable chest that you can purchase at the Test Garden, we don’t ship the chest.
