Fogger setup

[kairi]

I have an 18x18x24 Exoterra and the ZooMed fogger. I have a cork tile background as well. The fog needs to come out of the bottom instead of pouring out at the top. My only idea is to get an appropriate length piece of bamboo or something that the fog can funnel out of, and adhere it to the background. Does anyone have any suggestions? Or pictures of how yours is set up?
