Hello, I am getting my first bearded dragon (adult) and I wanna build it a nice home. I was planning on building this enclosure but replacing the doors with sliding plexiglass doors. I was wondering if I should replace the roof with a screen top (like zenhabitat's enclosures) or just have a few vents? If there is any other simple upgrades I can do please let me know! Preferably I don't want the heat lamp inside the enclosure, I prefer having it on top. Thanks
