Hello, I use the Mistingsystem from Vivaria, (www.vivaria.nl) and it works perfect. Now i only have 4 nozzles in it but it can have up to twelwe attached to one pump.
I have it setup to a digital timer so it goes on three times per day, once in the morning and once late afternoon (19.30) and once after all the light goes out. This works perfect in my terrarium and it keeps a good humidity all night, and during the day it dries up a bit and the humidity falls down to 72% and goes up to 88%-90% during the night.
I only use the mistingsystems for my bigger terrariums and prefer to spray my smaller by hand, because when using the misting system on the smaller tanks it made the substrate way to wet and it never had time to dry up.
Good luck on your choice!
Best regards
