Breaking semihydroponics rules--part 2

[orchidphile]

Hi, everyone. Thank you for your replies on part 1 of this question. Here's another wrinkle:

I often watch orchid videos on YouTube. Miss Orchid Girl is a fairly constant presence there. She originally rejected semi-hydro. Then she started doing it properly, and now she seem to grow most of her orchids in it. Lately, she started something new: she's using an external reservoir with a microfiber wick to draw the moisture up into the pot containing the leca. Using this method, she often goes a long time between waterings--much longer than a week. The question is, will this method create problems over time? (She does flush the pots every now and then.) I know the water will lose oxygen over time, but wouldn't being wicked up into the airy leca refresh it?
