I've used Hydroton as SH medium for several years and my plants do quite
well. I've used it for almost everything, my only plants not in it are a
Restrepia and a Pleurothallis which are in perlite and Ludisia discolor and
a Calanthe which are in soil. I've bloomed Slc hybrids, Brassavola nodosa,
Den. nobile hybrids, Burrageara, etc. The worst thing about the Hydroton is
its shape, when one drops a pot the pellets roll all over.

Happy New Year everyone!

LTNS to those I used to chat with.

After 3 years of benign neglect, my orchids are demanding a more
sophisticated neglect. Hence semi hydroponic.

I cannot find a Canadian supplier for the PrimeAgra clay pellets that
Ray Barkalow of First Rays Orchids uses for his semi hydroponic
culture. (Of course I can buy them from Ray, but I am trying to avoid
paying UPS to ship rocks.) Does anyone know of a Canadian supplier of
PrimeAgra?

Failing that, has anyone used other expanded clay pellets called
Hydroton or another called Hydrocorn? Those are the two brands I can
find locally. How do they compare to PrimeAgra?

Thanks.
