    Thanks Katherine,my second bloom is almost visible and it,too dried out. Hope yours will bloom for you soon,they may be miniatures but the color of the flowers are to die for.

    how is your humidity levels? Also, your medium looks a bit large for growing Masdevallias. I find that a seedling bark mix or Sphag works well for them. They are cloud forest species and grow on moss covered branches with moss. there is high humidity, moisture and coolness in that environment.

    Ron, I keep the humidity levels at around 90% in the greenhouse. Very rarely it will go down to around 70% and yes you are right about the size of the medium on top,underneath is a mix of sphagnum and dendrobium medium to keep the tiny roots hydrated. I have a big problem with fungus gnats and orchids potted in fir barks are not bothered by them at all,hence i thought I would dress the tops with it. I will look to see if small or medium sized fir barks available to top dress them. When the greenhouse temps hits 75,I rush all masdevallias and one lonely Ada to the basement for the duration.

    Fungus gnats are hard to deal with but are not impossible. Water your plant with a mixture of one part hydrogen peroxide and four parts water. The solution will kill the larvae, but is harmless to your plant. Reapply the hydrogen peroxide solution once a week until you see that the fungus gnats are gone.
    Place yellow sticky traps near the infested plant to catch adults. There is also insecticides. Drench the soil with microbial insecticide, such as bacillus thuringiensis, more commonly called Bt. This is the most effective way to kill any fungus gnat larvae.

    Thank you Ron! I will definitely try hydrogen peroxide/water solution. Got Bt under gnatrol but didn't do anything good and ended up with a nasty stink in the greenhouse to the point nose clip stopped working. Got the yellow sticky tapes all over it catches some adults and many orchids leaves along with my Spanish mosses.

    I'm off to SEPOS now,decided to spend the night in Philly instead of getting at 5 AM and still getting stuck in the early rush hour on a Friday..oy!

    Will snap some pictures.

    I hang it off of long plant stakes. This way it in nowhere near the leaves or medium.

    Have a great time at the show and please take some pics for us!
