As long as you clean the glass it won't hurt your lumens at all, if anything help them out a little bit, Take a flashlight and turn it on and look at the light then turn it off and take the glass out and turn it on and look at it, its more focused with the glass in than out.The glass bottom is a good idea.I have been thinking of that also,I just don't want to lower what little lumens I have or block any uvb as temps are not a big concern for me,ive been holding off from adding a glass/plexiglass bottom.
