Coarse Perlite ~ Oak Hill Gardens
Lately, the local co op's "coarse" perlite has been more dust than usable perlite so I was looking for a new source.
I just received my order from Oak Hill Gardens. I can't tell you how pleased I am. I need to add I am in no way affiliated with Oak Hill Gardens.
If you need to order in bulk, this is the place. Service was fast, shipping reasonable, product as described with little to no dust.
I have also posted this on the AV forum.
