Re: Seasonal Changes in Husbandry
I'm in a dry-winter-air climate too (but snow in September? Yikes!), so I run a humidifier in the reptile room during the winter, and try to maintain 50% ambient humidity (I don't measure humidity in frog vivs). It is a balancing act between maintaining adequate humidity and destroying the house with moisture in the walls; negatively pressurizing the house has helped keep the walls dry.
I use acrylic inserts on top of Exo Terra screen to maintain moisture. In summer, I cover about 50% of the screen, in winter closer to 80% of the top gets covered by using larger acrylic pieces.
Ambient temps can fall to low 60s F in the winter. The frogs eat less then, so I feed less (both frequency and quantity).
Watching the frogs helps a lot. If they eat less (i.e. more FFs left over), they are getting cool and I feed less. If they hide more, the viv is getting dry and I either cover the top a little more, or add a hand misting mid-morning, or let them hide more.
I think I could turn and live with animals, they are so placid and self-contain'd.
