[APD] Profile Substrate
I finally found a local place that sells Profile products. Apparently
all you can buy in the LA area is either Turface (too big), or Profile
"for Greens" (a golf course thing). The Profile for Greens is almost a
sand ... very fine
(http://www.profileproducts.com/golf/ppc_sand/index.cfm). I have read
just about every post in the archives that even has the words "profile"
and "substrate" in them, but I have one question: does anyone use the
fine-grained stuff, and does it hold down plants? I read where Chuck
Gadd had a problem getting Profile to hold down some plants. I don't
know what grain size he was using, but my hope is that it was a larger
one. It would seem to me that the larger the grain, the less contact
with the stems and roots, which would mean less frictional resistance to
floating out of the substrate.
Anyone? I'm too poor to get 175lbs of Fluorite, or 220 lbs of Eco-complete.
