Welcome to Terra!! Way to come in and make a splash with the 'Big guns'! Congratulations on your success with the campy!
- what are your conditions? (humidity, lighting, watering/spraying schedule, temps, etc)
- I got some xaxim (or something similar - treefern roots) with an order a few months ago but have been scared to try it - seems like it would dry out very quickly... Also, mine appears to have a lot more air space between the little branches. There are different densities of the material? I think I would feel much more comfortable if the little branches/roots of the slab were more densely woven
- You just tied the LFS, the campy was growing in, onto the xaxim slab and it took off - growing into the slab - right?
- how long have you had it growing like this?
- what is the slab tied to in the 1st pic?
Tobias also has some growing vertically (on a rock?) and only says that the air is "slightly humid".
As for the drying out part, I have some of the dense pieces cut into 2" X 3" X 1/4" slabs and they are hanging on the walls of a vivarium with constance 60%+ humidity. The tree fern does not dry out throughout a week, I rewater them once a week and they are never dry. The slabs hanging close to the fans do dry out along with the less dense pieces. You could do a dry run with the slab + mounting medium but minus the plant, and just see how it goes.
So far I have been avoiding mounting Utric's on mounts because I think they would be harder to keep from spreading and contaminating other Utric's. I would agree it probably would be a prefered method of growing alot of them. The results I've had with U. graminifolia on driftwood would support this even with non orchidioides.
I would think the more open mediums (airflow to the "roots") is the reason for the improved results not the horizontal position. I've been moving over to more open mediums and I've had nothing but good results. (Warning for the newer people...My vivariums are ALWAYS over 60% humidity, your results may vary greatly)
You can always try the xaxim with some less demanding species
By the way, what are your watering methods for the rest of the group? Really interesting with the alpina kept as an aquatic affixed, I know that U.longifolia can be found growing this way in the natural habitat. But I just can't get the watering of U.geminiloba right. This utric has been always one of the most demanding for me, what are your conditions? Also U.praetermissa and U.endressi don't do as good as I'd like them to in my collection. U.quelchii grows in the same conditions perfectly, as well as the weeds (reniformis, alpina etc)
RSS's flower thread.
I received a U. praetermissa in the fall (Sept 20) with one large leaf and at least one large obvious tuber (>0.25"). I potted it in a netpot w/ 100% live LFS. The single leaf died within a week or 2 and nothing obvious has happened since. I have been trying to keep the pot on the dry side (but possibly not dry enough?). Sometime I'll probably need to start digging around to see if it's still alive & non-rotted down there (but I keep hoping for a new leaf).
In the 1st post in this thread, there is a link to a Belanger CPN article where he recommends a hard annual dormancy which helps to produce good growth & regular blooms (definitely recommend reading).

Later edit: While I was doing my morning misting, I decided I had waited long enough and I checked the U. praetermissa - bad news. No tubers and the only quasi-recognizable remnants of roots were rotten. While the inside of the pot was not really wet, it had more moisture than I expected, given that I was trying to keep it 'barely wet' (aka: mostly dry). So that stinks!
Now that I was in there rooting around, I remembered Peter's xaxim post. While I'm not yet ready to jump head first with my small U. jamesoniana (even though that probably makes more sense), I took one of my small U. asplundii 'spares', removed it from the small cup it was in and tied it and the LFS it was on to a treefern slab (I had located the slabs last night, found that the 2nd one was more dense than the 1st). Wish me luck! Here's a fuzzy pic before it went into the tank:
The white lines are pointing to the leaves. The small ones on the right & left were visible in the pot but the newly unfolding larger leaf in the middle was hidden by some live LFS. I tried to keep most of the visible roots & bladders on the treefern side, behind the moss. The middle & right leaves are connected, the one on the left is soloing... (ooops)

One day while watering, me being the clumsy person I am, ended up knocking over my Utric. endressii. Thankfully there was no damage or so I thought. A few weeks past and it was time for my monthly clearing out the debris from the hydroton. Much to my surprise there was this tiny little leaf with a chunk taken out of it. It was still green and could only be from one plant in there. So I very quickly threw some potting medium into a cup and gently laid the leaf onto a moist spot. I forgot about the little guy for a few weeks, figuring his death would come soon. The next time I went to check on him, he was growing a root! Ok, so know I'm thinking I should actually try and take care of the little one. Well last weekend while watering I noticed some growth! The entire leaf is about 1/2".
The morale of this story is that you can it would seen grow Utric. endressii from a leaf pull.
Every good story needs a photo.
that IS exciting! dont think anyone is willing to do leaf cuttings out of their precious orchidioides! that being said, i suppose the chances of striking depend on how much of the base leaf you have? something similar along the lines of petiolaris dews?
