Single room cooling question

[Grandma M]

I grow some of my orchids in an extra bedroom,10 X 12. In the summer, with all my lights on, it gets quite hot in there. I am thinking about getting a single room cooler, evaporative cooler, swamp cooler, or what ever it may be called. I want to also use it to increase the humidity.

I have AC in my home but that room is the farthst away from the unit and I don't keep the AC on at all times, only when necessary. The home AC is not able to cool the room enough for my plants to do well. Even with all my fans on, it will sometimes get 95 or even more.

Has anyone had experience with this time of cooler? Any suggestions on what type I should buy or what brand?

Any help or suggestion will be appreciated. TIA
