I thought I would start a thread to revisit semi-hydro to talk about my experiences with it and to get feedback from others who have seriously tried this method of growing. I tried it in a fairly big way with 15-20 different Hoyas rooted and grown using both Hydroton and Prime-Agra clay pellets with a reservoir in the bottom. I went into this experiment very optimistically from everything that I had read about it.
All the plants rooted very quickly, but with very few exceptions growth stalled. Soon growth rates of plants grown conventionally were doing so much better that with only a few exceptions I pulled the plug on the experiment. Here is one of the success stories. Here is H. lacunosa around 10 months after starting from several six inch cuttings. There are currently around twenty open or ready to open peduncles on this plant.
