Hi Shakkai and Magnus, thanks a lot for the tipps. I will send an e-mail to Equatorial plants and ask them for advice. I have bought this plant (together with dendrbium pachyphyllum) at an Orchids show in Switzerland. Both plants come from a very good nursery here in Luzern (
★ Orchideenshop Luzerner Garten ★) and tehy gave some advice on how they grow these two species. However, I would like to have the feedback from some other people, in order to have a better range of conditions to play with, when trying to adapt them to my conditions.
I'll keep you informed what comes out of this
