I just purchased a really nice used terrarium with a glass ceiling. The price was just too good to pass up. Sliding doors and nice long vent strip in the back. All glass except for the corner strips. Any tips on how to install a basking light and attach the Reptisun fluorescent light? Upon further inspection to drill out a rectangle in the ceiling and put in a steel mesh and put everything on top of the mesh, would be our best bet. I have not been too successful Googling on advice on how to do this. Any advice is very welcome.
Buy a diamond tipped glass drill bit. Us oil to avoid the bit from grabbing the glass. If your trying to make a large hole start with small bits graduating to larger bits. Use your drill on a slow speed. Take your time, dont use much pressure. You only have one shot at it. You can use a stone drill bit to smooth out the hole.
This is really tricky. If your worried, you should be. I have lots of practice, I still get nervous.
