Armin,
I attended an orchid growing workshop last weekend where a guy from a nursery in my State who specialises in Masdevallias gave several presentations on potting, media, [as well as crosses, primary hybrids etc].
Anyway I realised the mistakes I have made before with spagnum moss and potting/watering and repotted all but 4 of my Masdevallias back into sphagnum moss [with bark at the moment].
The four that I didn't repot into sphag were:
Harlequin x Pichincha- putting out fat new roots leaves look good.
My 2
polysticta [already had one in true semi-hydro that has put out a new shoot but higher up]
Copper Queen
and a big
Sundancer x Yungasensis 'Bob' I divided and put the big division in SH [the other into sphag]
I made true SH pots out of plastic bottles [cutting the tops off and drilling two holes about an inch from the bottom]plus I boiled the hydroton and separated out the floaters.
The Copper Queen and Harlequin x Pichincha have much thicker leaves than the others and it looks like they have taken to being in hydroton with water wicking up from the bottom..
Tommorow I will take some photos
I did spend a long time using a wooden skewer carefully taking off the moss around & in amongst the plants that
I put back into SH.
I think if you leave too much moss it can stay permantly wet from the moisture wicking up and that leads to rot
I may end up repotting those in sphag back into true SH and I'm not sure if in the long time I will use SH or sphag. for all of them or both.
