Zoomed reptifogger using DISTILLED water on a digital timer works magic. I set mine to go on for 10 minutes every hour. Only thing you have to do then is mist once a day or every 2 days on moss and refill the zoomed bottle with distilled water when it runs low. You can even use a 2 liter bottle or large Fiji water bottle on the zoomed reptifogger as a replacement bottle.
