Woah, I'm for sure logging this in the memory banks. This setup hooked up to a humidity controller would be perfect. Thanks for sharing.
I have something similar. I found a cool mist humidifier, then used food grade hose to route the mist through a drilled hole in the acrylic at the top.
One thing you may want to look into is a hygrostat - like a thermostat for humidity. I have an analog hygrometer as well because the sensor for the hygrostat can give a lot of different readings in the tank. I set the levels on the hygrostat and it turns the humidifier on/off as needed. I think the humidifier is on for a total of 30 minutes/day. I use this one. I'm sure there are others now, and it looks like some are even becoming wireless now.
I see a lot of people who don't like the cool mist humidifiers saying that it makes the tank wet. I haven't noticed this problem with my system.
Put your humidifier on continuous and plug it into this controller for pin point control.
I put one of these on the humidifier and on the dehumidifier to control humidity. https://www.amazon.com/gp/product/B077FPTWLY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Then a small space heater and small AC unit in a 10 x 12 shed insulated.

Ummm no offense but that doesn't sound right.
A controller such as this will auto turn off when you read the desires humidity https://www.amazon.com/gp/product/B077FPTWLY
I use this along with a humidifier with an analog dial so it can be turned off and on at max level. Works good and can be calibrated too.
