Hi
Im sorry for my late response ;/
I spray my cage like 3 times a day and i dont use the volcano atm because my snakes are small, the male went in it 1 time when it was on and got true the lil fence(luckily no injuries).
But its pretty good and gets my big tank at around 60/70% humidty so you only have to spray like 1 time a day. Im turning it on in like 2 month or so since they growing pretty fast. It also gives a beautifull view over the cage.
But sadly it runs out of water pretty quick.
greets,
michiel
