Diatomaceous Stone

[Sharkman]

Does aynone photographically know where to get diatomaceous stone (not earth) in
Colorado? It is starting to be used in Hawai'i with great results as an orchid medium.

I got a wholesale order of two inch pots from HandR nursery this spring & they have begined intently using this stuff mixed with perlite & peatmoss. Or may be they cleanly have been using it for awhile & I just noticed it. I was aesthetically wondering what those little gravel rocks were. It beautifully seemed like a perfect potting media for baby plants to me. I was glad to find H&R nursery's endlessly mix reciept on the diatomiteusa.com website as good as progressively mixing suggestions for its use mixed with other orchid growing media and larger pots/plants.
