    Some great plants, thanks for sharing the photos Ron! Nice collection of various U.humboldtii, I noticed it slows down a lot it's growth a few weeks after repotting, he sure doesn't like it.

    Thanks for the generous comments. I just hope that now that I'm increasing hours of light that some of them will bloom (especially the big, robust ones).

    If this is true, it's probably due to my lower humidity. In the winter, the combination of much lower air moisture levels in the house and lower temps - hit my plants hard. First, I kept reducing the gaps over my tanks (to hold the humidity in) but then noticed that the cold air in the basement was causing massive condensation on the glass. I've insulated most of the tanks exterior so the humidity should be higher (but the meters are being shipped - so I'm not sure what level is). Next step is to install small fans inside the tank to increase air circulation & reduce stratification (bottom is very humid, top is dry).

    That's the thing, growth actually increased for a month or two after the repotting! None of the plants showed any signs of distress and started to grow & add leaves very quickly. Then my largest started to regress. It was quite the turnaround .. hopefully it will stop the slide & restart it's good growth...

    Time to see some flowers ...
    All the best,
    Ron

    Thats kinda funny, I can't get mine to lower and you can't get yours to raise. I "thought" I hit the sweat spot in one of my vavariums...but 6 days later...the UG pot looked bad and too dry . Good thing its a weed. I'm blaming it on unusually warm winter here.

    Since I'm setting up an Utric. nephrophylla tank here: http://www.terraforums.com/forums/sh...d.php?t=125487

    I'm taking down this little setup and going to reset it up with probably some Utric. tridentata to see how that does.

    Anyway I figured someone might want to see the results, this was planted with a single stand layer of LFS topped with ADA aquasoil. The light levels were pretty low, thus the taller growth. Divisions of this one moved over to medium light levels quickly resumed normal growth but stopped flowering. None of the other nephrophylla pots I have in other conditions grew as well or flowered as much as this did. Over the last 6 months or so there has always been an open flower or a stalk heading up. I filled the undrained container once a week. I've replicated smaller setup's with mini-african violet pots filled with ADA aquasoil with good results, but the flowering never took off like this.

    The dish as it was today.
    Utricularia nephrophylla

    After I removed the driftwood.

    Yesterday, I set up a bunch of small cups of Aquasoil for utrics, including U. nephrophylla, U. pubescens, U. warburgii, U. blanchetii & a small form of U. reniformis (so far). If U. geminiloba ever volunteers an aerial stolon or looks big enough to safely divide, I think I may need to try some of it also. Iirc, it shares it's lithophytic tendencies with U. nephrophylla - so maybe it would work....
    All the best,
    Ron

    OK, an update on U.campbelliana. The flower stalk is much bigger now, but it seems the flower has taken out a lot from the plant. Most if it's leaves are dead, only one clump and a few small ones are left. I think it's normal though, such a small plant needs a lot of energy to form the flower whicg is quite large compared to the size of it's leaves.

    campbelliana redux

    Well, I'm jumping on the tree fern bandwagon myself. I was not satisfied with the current growth of my U. campbelliana so I decided to drop back and punt.

    Upon unpotting I was pleased to find nice subsurface growth. I found it interesting that the growth was limited to the top 1/8-1/4" of the substrate. I didn't notice any downward tendencies.

    I had a 24" half section of tree fern trunk and an extremely slow growing sphagnum species (less then 1/2" per year) that seemed perfect for this application.





    I'm letting the trunk hydrate a bit in a new sphagnum culture before placing it in it's new home, she was bone dry.

    Wish me luck

    so apparently, quelchii was going through "me" withdrawls while i was away and desperately wanted me to come back home....so, guess what it did for me while I was away:



    coming back from seeing campbelliana in the wild, i was surprised to find that it does not actually grow on porus media, like our tree fern, but on solid, SMOOTH tree trunks with the aid of epiphytic moss. a slight scratch on the moss indicates that campbelliana, as well as the moss is grown very VERY thinly across the tree trunk, just one plant layer thick...

    that being said, if it aint broke, dont fix it.

    Very cool!! (now if mine would only do that!!) If the stalk aborts now that you're back, the plant might be trying to send you a different message ...

    Wow! Great info.... That sounds ideal for one of those water-filled clay containers that one of the orchid-folks told me about (Swords, RSS, both?). There is an orchid grower who uses sealed (on the bottom iirc) terracotta drainage tiles filled with water to grow epiphytic plants on the outside. The tiles sprout all kinds of small mosses. If I remember, I'll look around for the pics from that guy's site (unless someone beats me to it...).

    Congrats on the U. quelchii stalk and looking forward to the tons of pics from your journey - as well as the stories ...
    All the best,
    Ron

    Here is one of them http://www.swampstick.com, I've been wanting to try humbo in one of those but have not gotten around to it. They use the old terra cotta water pipes overseas with great results.
