I have several orchids, from Trader Joe's mostly, most of them Phals and a few years old, no humidifier added ever. They get morning bright light from sitting at a big window and I water maybe every other week. I removed the moss they came with to better keep an eye on them. I agree, some roots are looking like they are rotting from being to wet.
