Ray, what is the difference/advantage of your semi-H system {as so well
described on your website} and the original {?} Swiss Luwassa setup,
which I am using currently in windowsill and sunroom environment with
not very great success. The only specie which does fairly well are my
Dends. I am sure to have followed all suggestions and have experimented
in many ways on my own, but I am not able to get any good root
development before rot sets in. What are the basic differences between
the two systems?
