Redtail,
I guess it depends on what your compost is. If it's high in LF sphagnum then once a week would probably suffice, assuming the humidity is high. If you use a courser mix, you can water daily, as long as it's not standing in the water. Some of my plants can stand in water (very shallow) for a while, but it's not something I would recommend to anyone as advice. One should experiment with that sort of thing.
Also, lowland plants tend to need more watering because the high temps cause more evaporation.
Maybe if you gave us some more details, it might be easier to sort out this question.
Regards,
Joe
