Hello forum,
I've had a U. Humboldtii for about 3 or 4 months now, growing so painfully slow in an undrained container of lfs and perlite. I had some more in another container, but they're gone now :/
The whole container had a huge algal problem, and I recently noticed it had a strong 'sweaty' smell. Apperently it's smell of sulphur created by bacteria.
So today I repotted them with 1:1.5 lfs:perlite mix, with a thin layer of live sphagnum. I'm not sure if this is a good medium for them, as a lot of posts about humboldtii had them in some sort of peat mix. They were quite cut up in the algae washing process, so stun is pretty much expected.
One question i couldn't quite find the answer to was the water level for humboldtii. Can I have them standing in water? Or do they like it airy like the epiphyte that it is?
I really hope they make it since they're one of my favourite utrics. Also was pretty shocked at how big the bladder was for such a young plant. Well over 4mm!
•Apologize for making this post so long, but last question: When potting utrics, is it necessary to try and cover the whole rolon system or can i leave them above ground?
Cheers, Ray.

Hi Ray, Humboldtii is an emergent aquatic(grows beneath a thin layer of water, ~1" deep, with growth above and below the water level). I grow mine in sphagnum or sphagnum:sand/gravel mixes. As for repotting the stolons, I usually have them only partially covered to allow for anchoring in the substrate.

My humboldtii has been growing for years and does very well except when I neglect to re-pot it. It seems to dwindle if I don't change the medium ~ every 2 years. I use one of those little plastic dishes which you see at all sorts of garden sections of stores. Put a layer of LFS in the bottom 1/3. Put the plant-bits on this. Fill to 2/3 with LFS. The water level should vary between 1/3-2/3 of the depth of the dish. Warm/bright light, high humidity. Wait.
For repotting terrestrials use 1:1 peat-sand. Bury the bits just under the surface. Leave green bits showing above the medium.
