Do you think a 100w would be enough or should I opt for the 150? I plan on getting the fluckers lamp with the dimmer so it should make life easier. I figured it would be nice to be able to dim it down at night but still have a little heat. And does it dry out the terrarium any more than other heat sources? I plan on creating a false bottom so humidity shouldn't be too much of an issue (I hope). I'll admit I'm not too excited about the cold, dryness of winter approaching quickly! At least my frog will be comfortable!
