I run multiple mist heads, so when system runs, everything gets wet pretty quick.
For one misting each day, I run longer not to get things more wet, but to give more time to stimulate the lizards brain to do some drinking. That's the idea anyhow, it is not like I've spent a lot of time watching them drink.
My veiled is currently in a Dragon Strand Larger Breeder (21.5"x16"x44.5") with four mist heads, three inside and one up top to create a rain spot, and my quad is in a Reptibreeze "Large" (18"x18"x36") with three mist heads inside, and two on top creating a larger rain spot.
The schedule is:
8:00 AM - 1 minute
11:00 AM - 5 minutes
2:00 PM - 1 minute
5:00 PM - 1 minute
I am not a long time cham keeper, I've had the veiled for about 5 months, and the quad for about 10 weeks. They are both growing and seem to be thriving.
