Stefpix, Rambutan is pretty hard to grow in a non-tropical climate, just thought you'd like to know. My father had one and it didn't make it, even in a subtropical climate like ours.
Reed stem Epis kheiki all the time when they've been very stressed. It's not uncommon for them to go crazy like that.
Coconut husk is fine as a growing medium, it's been done before, and many people have had success. The only thing about coconut fibers is that they'll retain the salts from your water and the fertilizers you use. You gotta rinse it out good once in a while to prevent the salt build up. They also retain water pretty well, so the rule of watering everyday may not necessarily apply, you just have to be observant and watch what you're doing.
There's only one orchid I grow that must either be grown on tree fern or coconut husk (like yours), and that's Constantia cipoensis. That's because they don't grow on real trees, they grow on a "shrub" called Velozia which have fiberous stems like that of the coconut husk. If grown on actual wood, they just don't do so well and eventually give up and die.
