The tech sheet (link on above page) states that the pH is 6.5. I had seen a few earlier posts mentioning pH being too high but this is slightly acidic so I think (?) it could work for seed starting.


Any advise would be welcome. I usually just use commercial germinating medium for starting seed. Would love to try a DE medium if it reduces damping off/fungus but I also don't want to waste precious seed.



BTW Grainger lists 3 DE-based sorbents (not counting one that is "scented"):

As long as the EP Minerals Floor Dry is pure granular Diatomaceous Earth, that'll be the one to get for seed starting or a soil amendment. I see Granger has Floor-Dry which is Medium-Coarse Granules, Optisorb (Large Coarse Granules) and Solid-A-Sorb (Fine Coarse Granules) See the PDF Sell Sheets for details on each product at Granger.



You may also some at Autozone also as well as other Autoparts stores.

I see Autozone has 2 EP Minerals DE products, one called Oil Absorbent DE 25lb and the other is EP Minerals Floor-Dry 15lb. I don't know what the size of the granules are if one is coarse and the other is finer
I still have a stash here that I bought years ago, so I haven't bought any recently.
