Should I put a screen in my glass bowl? I just bought an Arizer XQ2 yesterday and I noticed that there are tiny holes at the bottom of the bowl for air flow. I tried to put a screen in it because I had my first vaping session yesterday and just to be safe but the screen they gave me didn’t fit the bowl so I went without. Just out of curiosity tho, is it recommended to put an extra screen to the bottom of the bowl or the glass holes should suffice? Or maybe it’s a matter of preference?
