Yes you will also lose out on UV the best light for your plants are open hoods but I would only have open hoods if you can controlle the temp in your room

You lose something like 5% for every piece of glass the light passes through. And yes, the bulb counts as one also. So you now have 3 layers. If you have to air cool then you have to do what you have to do. Its not much of a loss but it does take away from bulb performance.

Bare bulbs are so much better that it's worth reducing your heat signature to remove the excess glazing.

I heard that 5% is the absolute least the glass will impact your light output; not only does it cut some spectra more than others, but the moment it gets dusty your lumen loss will skyrocket.

I run an air cooled hood without the glass. My homie suggested I take it off , I took it off. My setup is as simple as it gets ,it's dumb simple. But it works well. Canopy stays between 76 and 78 root zone stays between 71 and 74 . I just gotta keep my house at 78.. In the winter I won't need to do that.
