I politely disagree with jbigio on this detail of watering. When I grew these, I started watering very lightly as soon as I saw roots, gradually increasing in frequency and in volume of water as the roots grew. I do mean gradually too, it took me maybe a month to go from no watering to watering full on. I was always very careful not to get the bulb nor the new shoot wet when watering as the old bulbs do seem to rot easily.

They typical cycle for this family of orchids is that they grow very fast and the bulbs mature (during which they are watered/fertilized heavily), once mature the leaves start to drop (during which watering is gradually reduced), once the leaves fall off they go dormant (no water), then they flower (some Cycnoces will flower before the leaves fall off), then they do nothing for a while (no water) before starting a new growth (gradually start watering again).

I also wish to politely dissagree with Jerry on a different small detail. While I agree that the orchids in this family never form large clumps like a dendrobium or cattleya might, I have seen Cycnoces and Clowesia in shows with many pseudobulbs, as many as 5-10. Clowsea rosea and one of its hybrids Clowsea Rebecca Northen seem to hold their bulbs better than others and its not uncommon to see one at a show with 5 or more bulbs. They do grow really well from single bulbs though and for this reason I typically see commercial growers dividing them up into single bulb divisions for selling. Mormodes seem to hold only about 2-3 bulbs at a time. I've never seen one with more...at least that I recall.
