I grow my Paphs in Greenmix (as a window sill grower it seems to help me keep the humidity up - albeit I'm still a bit handicapped in this respect, when compared to the lucky owners of a greenhouse):
"GreenMix for Orchids is a mixture of water-repellent and water-absorbent granulate with added perlite and lignite. The granulate is made from stonewool, the basic element of which is diabase rock. GreenMix for orchids is produced by Grodania A/S" (and was developed in cooperation with our local mastergrower, Hans Christiansen - whom the variety Paph. hennisianum fma. christiansenii was named after)
In my local orchid society there is quite a religious war going on about growth medias...but I guess, it's the same every where?!
This actual plant is grown in an east-south-east facing window...at room temperature, i.e. mainly around 18-23 degrees celsius.
I use 3/4 spring water + 1/4 tap water (NB. tap water in Denmark is quite clean and you drink water directly from the tap). I fertilise once a month, except nov-jan (quite dark months up here north), with Pokon 20-20-20 (NPK 20-20-20 + Molybdenum (MO) 0,0005% Bor (B) 0,0200%, Kobber (CU) 0,0500%, Jern (FE) 0,1000%, Mangan (MN) 0,0500%, Zink (ZN) 0,0500%)
I think, that's about it!
Kind regards,
Jens
