Interesting thoughts. Kenni, Motes, that does seem sound. But in their
monthly newsletter they repeatedly point to the "water first, fert second"
as being incorrect. Having said that, some of our larger Vandas have such
thick roots that feeding with a wand would take forever if they were not
watered first. So we let the watering system go on in the AM as usual and
fertilize a little later in the morning. They seem to like it.
