Ok, I need some critiquing of my thought process here.
I know that evaporative cooling (swamp cooler) needs low humidity to reduce the temperature; that it can only reduce the air to the wet bulb temperature, which is a deviation of the current temperature and humidity. For example, areas with lower humidity (areas like Arizona) work well with swamp coolers, while areas with high humidity (e.g. Florida), they do very little. So could a terrarium, which has a higher humidity than the surrounding room, be cooled by a evaporative cooler? The cooler would be outside the terrarium and blowing into it. For example, 40% room humidity, 80% terrarium. Would the swamp cooler reduce the terrarium temperature compared to the room temperature?
Anybody doing this for their highland chambers? I get night temps in the low 60s from my basement, but would be interested in getting it lower to try more highland neps.
