| I pot Phalaenopsis in a reservour system for gifts to non-orchid types with excellant results. Phals never want to dry out and the system keeps them uniformly damp.
I grow most of my orchids in a hydropnoic pellet (AliFlor brand) but without the water reservour. I like this system as hydroponic pellets can not retain more than 10-15% moisture so overwatering is difficult. The pots dry out faster and require more frequent watering and must be fertilized regularly. But this method means I control the water and fertilizer.
Using these types of medium growers should be aware that salts and fetilizers build up on the pellets. They must be leached regularily. Also know many like AliFlor (clay expanded with air) can float and will float right out of a submerged pot. Flush from the top.
Now I also grow Lady Slippers in a vase of water, but that is a future thread.
