Before we left for a week, I came up with this to keep the tent moist. Old humidifier only has a gallon and a half capacity. Would not last a week. I am still using an electrical heater outside the tent. It blows heat thru a lower tent screen. Heavy duty heater. It shuts off it it tips over. So I put bucket rig in a good spot for it to get the heater. A dish towel long enough to reach the bottom of bucket. A tether holding the plastic hanger. I tried it for a few days before our trip. It WORKED! Water did not lower noticeably. Kept the RH @45%. Now I water her once a week and a humidifier that can go for days.
