Hi there win_67. In my readings on the internet, I had noticed people mentioning that putting a tray of water below the pot doesn't do much (or even at all) to raise humidity around the plant. I think what they mentioned makes sense.
Good air circulation around the plant and an appropriate watering schedule (and appropriate growing media --- eg scoria, or bark etc), comfortable temperature, and enough light are the main requirements for keeping the orchid in good shape.
I've never grown a Phalaenopsis plant before. But I successfully grow Paph and Phrag. I'm thinking that if I can grow Paph and Phrag well, then I should be able to grow most Phals well too.
I have found that if air-circulation is good, then growing the orchid (eg. Paph and Phrag) in scoria, in an opaque plastic pot with very good drainage holes (at the bottom), with the pot sitting on a "drainage grate" ----- does a very nice job indeed. I grow my Cattleya and other orchids like this too. Same setup. It works excellently in my part of the world. I attached a basic drawing image in this post.
The other attached image shows a Paph. Saint Swithin 'Jill' growing in scoria. The photo was taken soon after using a watering 'wand' (aka weed sprayer nozzle) to water the growing media. On the following day, that surface layer will be dry. The scoria inside the pot will still be moist. So it's a matter of understanding when to water. With good air circulation, and airy-enough media (eg. scoria) - this orchid and other ones generally have no problem with getting watered every day.
My trick is to occasionally allow for a temporary full dry out inside the pot, every once in a while ...... eg. once a week, or once every couple of weeks - or whenever I see fit. No fixed schedule really. The idea (whether it's right or not) is to make things hard for unwanted activity inside the pot (growth of unwanted things).
They (some people) say that certain orchids can have issues with drying out inside the pot (everywhere in there). Interestingly, I haven't encountered that issue with the Paphs and Phrags that I'm growing - also Oncidiums, and Psychopsis.
If bark is used, and if the bark is brand-new (and dry), then pre-treat the brand new bark with a decent soaking in water before potting the bark. This allows the bark to be primed with water. This may be important, because dry bark repels (rejects) water - like water off a duck's back. With scoria (lava rock) ...... no problem. I don't use bark. I find no need for it for my purposes. However - a bark or bark/perlite mix is really great for those that want a different watering schedule. This is when bark or bark/perlite mix has its advantages and benefits too. These are great media to use too.

I use light dose .... one-quarter to one-third the factory recommended strength. Once a month application ---- into the media and the roots.
