Really....you've had luck with just spreading the seed in various locations and on sphag?
I have been working on several flasking projects, so I was planning on flasking them (trying to find the correct medium was something I was trying to find info on...I tried flasking some Masd. Webberbauri and evidently they don't like epyphitic medium)...but the seredipity of spreading the seed around with some of my other plants seems like an interesting idea.
