I read a lot of threads about semi-hydro growing and thought I would try it for a new challange. The only plant I had was a piece of Phrag. Calurum that I had just divided.
This plant is in an 80mm disposable cup from the super market, the holes (3) are 25mm up from the bottom and the medium is straight Hydroton. I keep the water topped up all the time with a good flushing when I water the other plants. It just sits in the GH with everything else. It gets food with all others as well. This has been done over 12 months, I think. There was one root on the piece before potting.
