These will not go well in SH.....they are both terrestrial species, so i would just grow like you would a normal potplant-in a nice rich loam, 2parts potting mix, 1 part sand and 1/2 styrofoam packing pellets (ie, 2 cups, 1 cup, 1/2 cup). Keep them moist, but not wet. An annual fertilising with a slow release is fine, the Pleiones LOVE a cold snap in Winter, considering they naurally get covered in snow in the Himalayas, and the Calanthe likes to be kept at the least, at 10C. The pleiones i have done some experimentation with....they will grow under 70% sunlight, or 70% shade. The Calanthe prefers more like 50/50.
