Here is a link to some photos of what I did to my 29 gallon tank a while back. What I did to the top helped alot with the temp and humidity control and was easy to adjust. Also, make sure you check the ends of your vines to make sure there are no built in hanging loops. Another forum members snake just got caught in one a few days ago. Hope this helps...
