It usually depends on the temperature and the depth of the pot. If you growing them outdoors in hot, sunny weather, they'll need a lot more water than if they're growing indoors on a window sill where there's going to be less evaporation. The pot should also be at least six inches deep, especially if you're going to let them stand in a tray of water. That way the soil can be pretty wet down deep, but it'll stay just moist near the surface where the rhizome is located. If the rhizome stays too wet, it will rot.
I always try to replicate the conditions where VFTs grow wild in nature in damp bogs. They get plenty of sunlight, but the soil is nutrient poor and stays fairly wet most of the time, at least several inches down below the soil line. That's why I grow mine in pots that are at least 6-9" deep, in as much sunlight as possible, with the pots standing in trays with an inch or two of rain water most of the time. When I bring them inside over the winter, I only water them once every week or two, just enough to keep the soil damp but not too sopping wet.
