I'm sure after you set everything up you are going to laugh how difficult it looked now lol

you can modify any ultrasonic humidifiers, the ones they sell everywhere to use at home, you can get the least expensive one, then get a hose from any home improvement store that would fit the hole from where the fog is coming from and silicone it in or just tape is with something, so it stays in place, that is it you can check I'm sure there are a lot of videos on youtube and threads on here about it. it is really easy.
