I think you live in California don’t you? How do you keep Jackson’s in California? It seems like the temps would never get low enough outside to be able to do this unless they are all in one room with an large ac unit just for them And plenty of humidifiers. My Jackson’s is in my living room with a window with a small ac unit right next to him.You don't need to glue the pipe joints because there will be virtually no pressure. I take mine apart periodically to clean. If you use distilled water in your humidifier it stays a lot cleaner.
That may not give an accurate picture of the humidity where Eustis sleeps—IDK. I went through something similar. When I moved the probe to the middle of the foliage where he beds down for the night, the humidity was considerably (up to 20%) higher than out in the open. This is partly due to the evaporating mist water, and partly due to transpiration. I do not have a fan moving air through my enclosure; it moves naturally via chimney effect.There’s no probe, gust the little square gauges I have hung ant the top, middle, and bottom of the sides of the cage. I hung them by paper clips in the screen.
