Dendrobium Nobile

[Roberta]

Spraying the leaves won't do anything useful. Orchids take in water from their roots, pretty much exclusively. And it doesn't do anything for the humidity beyond a few minutes. So unless it is very hot (where it might have a slight cooling effect) not worth the trouble.

So-called "bloom booster" fertilizer doesn't boost blooms. Just not useful. (Excess nitrogen can reduce blooming, but the easy solution to that problem is just use less or in winter none).

as far as keikis go, nice up to a point (a bonus) but how many do you need? I think you really want flowers... they're prettier.

As for questions, keep on asking! A good way to learn, and you have the benefit of collectively, years of experience - and we love to share!
