I recommend foggers because they can be pretty cheap compared to rain systems yet affective. My current setup is perfect if not excessive; I have a Coospider Reptile Fogger Terrariums Humidifier Fog Machine Mister 3L Large Size which was around $50 controlled by a $40 Digiten DHC101 Humidistat. I also have a “little dripper” drip system and a continuous spray water bottle :)) Links: humidistatfogger
