Out of curiosity what do you have your humidistat set to? I've been playing around with checking humidity around the house and notice my house gets quite humid (I blame the tanks!) but more so over night.
Hmmm, from my research that's about where a house's humidity should be at, I hope my monitor isn't broken, or I should say I hope it's broken because here it ranges between 55 and 65
Really nice & well organized setup! Nifty approach with adding a PAR 38 for a frag section down below- more interesting than a ball of cheato. I wonder how long it'll take until you decide to turn the fireplace into another display tank.
