There is a user on Icmag named "Tangwena" who has obtained industrial ceramic metal halides without any uvb filter and has noticed a huge improvement in quality over other lights. Anyone heard of these industrial lights that give off more uvb? is there any way to take the uv filter coating off or regular CMH lights?
There are dangers involved you can get sunburn in the grow room and it is very bad for you eye sight and vision if you do not have eye protection but UVB brings out everything from higher THC to more aromatic terpenes.
