I couldn't decide if I wanted to put this here or somewhere else, but it kinda deals with the Nepenthes since the highlands are the trouble makers to begin with.
My vault temperatures are 75 during the day, then 60 at night. Humidity during the day sits at about 50 - 60% but at night goes to 80%. Why does that happen? Is this due to the 'measurement' of humidity fluctuateing with the temperature? Is the same amount of moisture still in the air, but the capacity fluctuating only since the temperatures are changing?
I'm curious if it's that or if the lights and heater are burning off the extra humidity. I'd like to see it at 70% during the day as well, but I'm having trouble bumping it past that level. Night time is no problem though.
