Growing a Vanda in a pot

[ChatteringCat]

I like how Vandas look, but we vacation often enough that I do not think I could care for one with exposed roots properly. When I spotted some potted ones at my favorite nursery, I bought one. It is potted in large bark chips in a bowl shaped terracotta pot with several nickel-sized holes in it through which several roots are emerging. There are also several roots coming out of the top. I bought it in spike, and one of the buds has opened. Most of the aerial roots are showing growing tips.

The tag had the unhelpful note of "Orchideen Vanda Hybride" on it. I could not find an English speaking nursery attendant (Germany) and everyone was super busy due to their Advent sale.

Attached (I hope) is a picture of what I have.

Two questions:

First, how often and what is the best way to water this thing? I can submerge it fairly easily (the bottom saucer is not attached, I was just trying to avoid setting the pot ON the roots) using a mixing bowl, but I am not sure how often I should be doing so. I know Vandas with free roots need to be watered quite often, but I was hoping this one might be able to go a bit longer. Suggestions?

Second, is there a list someplace of various lux ranges different orchids prefer? I have a light meter now, but I am at a bit of a loss on what to do with it.

You can leave it as is. In the house, pkan on watering (drenching) twice a week in winter, and every other day in summer.

If you travel, put it in a plastic box w water in bottom, to give it high humidity while you can't water. One week is not a problem; if you go for two weeks try to arrange for someone to come in to water.

Your tag says "Orchid Vanda Hybrid" but if you can go back to the store and ask where they got the orchid=chances are you might get the correct name. Looking at the plant and the flower it seems it is a Vanda Pachara Delight....but I am not sure because I have not seen the flower details.
Fairorchids gave you sound advice.
Vandas need warmth, humidity and bright light(your window in your picture seems to be the right place for good lighting).
Make sure they do not go under 50F(10C)....invest in electric humidifier with a small oscillating fan on the top for air circulation=fungi and bacteria infestation can sometimes develop on cold water droplets that dry in the sunlight....roots are light colored when dry and make sure to wet the roots until they are deep green that is when you know that the Vanda had enough. But these kind of orchids do not get root rot so do not be afraid to over water it=just don't let stagnant pool of water remain touching the roots for long where bacteria and fungi might develop.

I have all my Vanda types in clay pots. Right now I am watering mine once a week. I take them to the sink and let the water run until the bark is wet and the roots turn green. Mine are inside a home, 70 F during the day and about 60 F at night.
