Hi vass,

Can you make your topic title a little more descriptive in future.. it will help you get better response and save people's time from checking out this very vague thread.

None. you want an area void of oxygen.

If you add uplift tubes then you turn it into a UGF

spelt as Plenums

Just edited the title for you so it more accurately describes your post.
