Hi Tin, Yes. I read your post about losing the Masdie to rot, most probably because of the sphagnum.
I have been debating what to do when I put mine in the terrarium. They have been growing happily for a year now in pots with bark. I mentioned in one post that I have found it somewhat difficult to keep the humidity high enough in this situation, hence the move to wanting them in a terrarium. That said, they weren't in flower when I bought them, but they have both flowered twice in the past year; and they seem to continually be adding new leaves, so they must be at least moderately happy.
But, you're right, I don't want the opposite problem rot either! Especially in a cool environment. I guess I really want to keep everything nearly the same, but add a bit more humidity around the roots. Our humidity here is pretty high to begin with: on 'dry' like today, humidity is 52%, tomorrow it will be 81%. Of course, its slightly drier inside the house than outside...
The ones that you have that aren't in Sphagnum, how are you growing them? Are they mounted?
I'm thinking that if I can find a nice log like thing with an indentation or hollow, I can leave some of the bark around the roots and attach my Masdies there.
Then I just need to get a few more so that I have a brilliant display of bright purples, oranges, yellows, etc.
Many thanks, I can't wait to exchange some photos with you when mine next flower.
Cheers,
