over the years, i've read this and that about having a glass cover on your grow light.
i didn't use one for years but i've been using one that came with my sun light grow light for the last couple of years for no particular reason. i don't have a heat problem so i think i might take it out if indeed it will increase the UV reaching the plants.
do you keep the glass your unit came with in or take it out?
