dampsoil should be fine as long as the roots are not water logged. and allowed to dry.
possible reasons why this could be happening:
your plant could be dormant. plants do not require much water via the roots when they are dormant so you will notice that it will take much longer for the medium to dry out. .
not enough ventilation in a cool place or a very humid environment stopping the water from evaporating naturally. the pots you are using should be terracotta(non glazed), as that material would significantly speed up the soil drying time by allowing air to pass through the clay pot and all around the roots
