    My Orchidioides tub

    I decided to make a thread for the tub I am using to grow my Orchidioides Utricularia. The first post can be found in the section Orchidioides discussion thread.I started this a little more than a month ago, with Utricularia reniformis and asplundii. Currently in addition to those I have alpina, endresii, geminiloba, nelumbifolia, and praetermissa.



    I am using long-fibered sphagnum with some live sphagnum mixed in. When I first got the endresii, it was just a mass of tubers and traps about an inch across. Since then, it has made two tiny leaves.



    I was afraid that it would rot in straight LFS, so I wrapped it up in live sphagnum and it looks like it is doing fine. I have also done the same thing with the other species, with the exceptions of nelumbifolia and reniformis. Ideally, the top of the medium would be completely made up of live sphagnum, but I don't have enough so I'm making do with what I have. I have also noticed that some of the LFS has begun to come alive and grow slowly.

    Reniformis appears to be doing very well in this tub. I see lots of new growth and it has begun to spread, making many plantlets in the LFS. Many of these have leaves only a few millimeters wide. Surprisingly, most of the new growth is around the pieces of the plant that separated from the main one that I planted throughout the container, and not in the main clump.

    You can see some of the plantlets show in this picture:



    The praetermissa has also done better than I expected.





    The first picture is from when I first got the plant. In the second you can see that the leaf that was unrolling in the first picture has fully developed. The alpina was in a similar situation when I got it with a developing leaf but it looks like that leaf is not going to form, which really surprised me given its reputation as an easy plant.





    I didn't have enough live sphagnum to wrap that plant in live sphagnum, although I did wrap a piece of the plant that came off when I planted the first one. I don't know if the leaf in the bottom left corner was already there or not, but I hope it develops properly.



    I wasn't sure about the identity of the nelumbifolia (another plant I accidentally split into two while unpacking) I got until I looked at the bladders and saw a couple of leaves developing. The first leaf the plant put out was reniform, so I thought it was reniformis. But looking at pictures I had taken of the leaf before, I realized that it had slowly unfolded, which I have never seen with reniformis.







    I found the same thing on the other section of stolon when it put up a leaf:





    Also, the bladders are much larger than the bladders on my reniformis (and look remarkably like Utricularia humboldtii bladders to me), so I think I have the real deal. When I got the plant, it had what looked like runners, but I think their development has been aborted.



    I'm not sure if the geminiloba has grown. It came growing in a chunk of live sphagnum when I got it, so all I did was wrap some more live sphagnum around it and stick it into the LFS. I hope it doesn't just stay on the live sphagnum that it came in. I noticed a shoot growing up that I thought was either a new leaf or a moss sporophyte, but it turned out to be a Drosera binata leaf, which I am leaving in there for now.

    Just a really quick update.

    First, the "runners" on the nelumbifolia have started to grow!



    The one in the middle has gone from facing downwards to facing to the side, and the tallest one on the right has grown to over an inch. I'm not sure how high they were when I first got the plants, but now I'm more curious than ever as to what these things are.

    Also, I noticed that a stolon on the geminiloba has begun to grow outward.



    If you look really closely at the center of the picture, you should be able to make out a thin stolon. I should probably put some live sphagnum there for it to grow into.

    Very cool
    Have you ever had to deal with white moldy stuff on the top layer of sphagnum when growing utrics?

    Thanks! No, I've never had mold on sphagnum before. In one of my Utricularia tubs with peat though this became a problem. It looked like a spider web but was much thicker and I had to manually remove it.

    A few updates. I am now growing the plants under T5s for 10 hours a day.

    Both of the Utricularia alpina are putting up new leaves.





    So is the Utricularia praetermissa.



    And it has had a lot of stolon growth. I'm rather surprised by it because the layer of live sphagnum is pretty thin. It is nice that it tolerates dead sphagnum as well.



    The endresii is doing great! The leaf on the left is about half an inch tall, and it keeps making new leaves.



    The old foliage on the geminiloba has mostly died but it has put out a new leaf as well. Not as large as some of the original leaves, but at least it is still alive.



    The "nelumbifolia" appears to be nelumbifolia x reniformis, which I am very disappointed by.



    No pictures of the reniformis but it is doing well. Unfortunately, the asplundii doesn't appear to have grown so I am thinking of moving it back to its original net pot on a windowsill.

    I know nelumbifolia puts out reniform type leaves until an adult I think.

    Thanks! I asked about that here.

    Wow that's cool!
    I'd love to hear your precious opinions on my project Grow box with monitoring and remote control system
