I have been planning on buying an apogee reptarium. I have been thinking that they are metal wire mesh stuff, but after reading the description more carefully, see that they are nylon mesh . Now I am worried about getting one. Would the heat and UVB lamps burn the mesh? Would the nylon hold soggy bacteria? Will it rip easily? Please answer. I think that I might just free range now that I saw this. Maybe I just need reassurance. Thanks in advance for the help!!!
