Some of the Oil Dries are not pure DE , but OptiSorb is.
I have been using this brand for 3 years now. I mainly add it to my potting mix. It has good moisture absorbancy ( Over 100 percent of its dry weight but at the same time it wont compromise drainage.
Thank Bill, for a great pictorial demonstration.
