Hey guys starting the build on my Terrarium for a future beardie. And I have a 36"L 18"W18"H Terrarium and was curious if a 14" Reptisun T5HO would be long enough? Or is it too short? The terrarium I have has a "screen door" type screen on the top, split in the middle length ways. If the hood is set on top of it will the screen block alot of the UVB? I had considered modifying the screen by using some thin veneer wood to "frame" the light hood and then cut out the screen in the middle of the frame to un-obstruct the light has anyone ever done this would this be wise?
