But what are "all the screen advantages" that are gained by doing this?
haha mostly airflow! im not the one who really believe in the "he will see his reflexion and die of stress" I find for mountain they like a good airflow, sometime fresh breeze to the night from the windows its also visually ok too because no calcium acumulate on my top screen

I like screen and I like glass but mixing both work better for me
A better gradient? What's the humidity in the screen portion? Gradient in way that in top its not super humid, 40-55% basically almost same in my room. At the bottom its more humid and it get dry slower so if our want to drink 20 minute after the misting well.. its available!
Or rather, and maybe and, what in your opinion is the advantages of screen at all?
I like screen but.. its hard to have different parameter than the room where it is and its hard to get something really nice visually. Advantage for me is definitely the air Flow too me air flow is probably the only difference between screen and glass.. Are you a glass or screen believer?
Also why the high cost of the Exoterra in this case, as a 40 gallon breeder is about the same size (36x18x16) would work inch shorter, and much much cheaper.
Because I got the glass terrarium for something like 100$ because the top was screwed and.. I got my reptibreeze for 15$ (both Canadian $

) so I didn't care to cut and kill some part for experiments

Is the 40 gallons have an air flow trap at the bottom?
