Not trying to be rude here but I don't see why everyone always complains about tanks. I live in Iowa where it isn't very humid at all and I have used two tanks quite successfully. I have never had a problem with humidity or temps at all. The only reason I would want to do tubs is for portability. It is a pain to move my tanks all the time.

Don't knock it till you try it. . I started with tanks and thought they would be fine. Just switched to tubs, 1000x better for 1000 reasons.....
