coarse vermiculite?

docarwen(6)September 18, 2008

Can anybody suggest a vendor for coarse vermiculite in the Triangle area? I'd really like to find something in Durham, but so far all I've found is the little 8-qt (for $4!!) bags at Lowe's. That gets pricey when one sums up to 3 cubic ft!

Some of the other forums have had comments about loose fill attic insulation, but I can't even find that -- Lowe's, Home Depot nope...

TIA :)

Logan's Trading Post. Go figure.


If only they were in Durham... or I had thought of this before I drove all the way down there last week!!

Odd, I just read an ad for a lawsuit against vermiculite producers who promoted it as loose fill attic insulation because of its asbestos contents. Last page of the current National Geographic magazine (appropriate to GW with a sprouting plant on the cover).
WR Grace Bankrupcy for selling the stuff ..some of which contains naturally occuring asbestos..

Just a thought that using vermiculite to loosen soil or mix into potting soils..might think of using a mask when working with vermiculite.

Heh. There is a *lot* of discussion about the asbestos stuff on the forums that use it more (square foot gardening, seed sprouting i think). Apparently it's a lot of bad press stemming from one bad company about 10 years back, and now any vermiculite mine/vein is regularly tested for asbestos.

Having said that... Stone Brothers in Durham has 4 cf bags of coarse vermiculite -- and a lot of other miscellaneous garden stuff :) -- and I am seriously considering wearing a mask when I mix the vermiculite in tomorrow morning. Better safe than sorry, and I hear it's dusty until it's been wetted properly.

A 3 to 1 ratio of perlite to vermiculite mix is an excellent soil less growing medium for top drip Dutch bucket systems. See the following:
