When we first started growing orchids I did read some of this kind of material and we tried to fallow the watering and light recommentations but the plants just languished. Having been a gardener since a kid I didn't see how this was logical, but we tried it anyway thinking that orchids are indeed different.
We know better now.
Plants get repotted in presoaked bark as soon as they get home and watered thoroughly and put under the lights. They usually need water again in 2 days (but this depends on your growing environment) then again in 2 or 3 days after that. The drying rate also depends on the potting media and air circulation, and the water demands of the particular plant. It's best to know the plant and its perferances. Once the potting media starts to 'set up' then I find that they don't need as much water, this usually takes about 2 weeks for me.
Plants also need to dry between waterings so they can search for water by stretching their roots, this makes them develop a stronger root system.
