    Did I read right, you are repotting your dendrochilum wenzelii into semi hydroponics? I bought one in Feb. and I am thinking of doing mine. I have just started to replant some of my other orchids into semi hydroponics. Thanks

      Hi! My experiment into semi-hydro did not work with dendrochilum wenzelii. I eventually lost the plant. I may have had more to do with the lack of light in the room where I placed it. Good luck on yours.

    Hi! I have read your blog post about your Coelogyne Mayeriana growing on the big cork bark log and tried leaving a question for you in the comments, but it doesn’t seem to be working. I am really curious how that experiment worked out in the long run. I recently purchased a Coelogyne Mayeriana as well and it has been doing fine in semi hydro, but it grows so fast and wants to grow straight up so I think I am going to have to mount it, but am trying to figure out the best way to do that inside my house. The biggest problem I’m having is wondering how I will water it without getting water everywhere. Any thoughts?
