If enclosure is well ventilated, then light spray every 2-3 days, but never allow enclosure to become too wet.
A one inch layer of peat soil mixed with vermiculite can help to maintain humidity in a well ventilated container. Otherwise use kitchen towel and reduce ventilation until the towel is barely damp to the touch.
Clean enclosures (usually at most) once a month or if moldy, wash them with hot water as required, if detergent or bleach is used then thoroughly rinse off, perhaps even soak in fresh water overnight. Ideally, replace substrate monthly or paper towel when you replace the cut watered foodplant.
