SH question
I have a number of epidendrums keikis and a dendrobium in SH
culture. The Dend. is in a clay pot, the epis are in smallish plastic pots. The dend. seems to enjoy life. The epis have stopped growing. I think it may be caused by them staying wet too long (well over one week). The pots have holes 1cm/0.5in up the sides, I never leave any standing water in them. Only one type of expanded clay pellets are available locally. I need to exchange the pellets after about three months because of algae buildup which clogs the holes in the pot. The roots of the keikis that are in the bottom have started turning brown. Wether this is rot or dust from the pellets, I don't know. The pellets dry out about 4cm/1.5in down before I need to water again because the leaves on top have gone limp. The roots go about 10cm/4in down into the pot, but seem to want to spread out instead of going down. I see this as a problem - is it? Are there any tricks that will allow the pellets to dry out faster? Geir |

Exchange the plastic pots for clay orchid pots, they will dry out faster.

If you let the medium dry out, then you are not growing in semi-hydroponics!
What you are doing is merely growing in LECA using "normal" culture. If you try to do S/H but let it dry, then your plants won't develop the root cell structure needed to survive, and they will rot. The idea is to get them to grow roots accustomed to the constantly damp but airy conditions. If your epi's developed the correct kind of roots but are now rotting, it is likely due to insufficient warmth. -- Ray Barkalow First Rays Orchids http://www.firstrays.com Secure Online Ordering & Lots of Free Info!

I will try punching a hole or two extra in the sides of the pots for a bit more air circulation, and placing them in a slightly warmer location. They are close to a cold concrete wall right now.
