Hey y'all I have reached an impasse.

I have a 30 gallon which is to become an immenant home for at least one Whites Tree Frog. Now, these frogs have a penchant for plant destruction, however I have a fondness and a green thumb (I have 10+ orchids, a few bonsai, and my goldfish tank is furnished entirely with living plants.)

Now my dilemma is such, and thus I need some advice with from some experienced vivarium-growers... what would the time frame be to allow a pothos to grow into the habitat, to the point where it is more or less hardy enough to withstand my hypothetical tree frog molestations?

Obviously there are a lot of variables in this equation, so what I am thinking would be the most helpful would be anecdotes and learning lessons(errors). Also, how quickly does pothos grow in, and what fertilizers are most effective?
