By the way moisture. In that tube below ambient temp. humidity will creep
up until it will reach 100% and stay there. It needs to be back filled
with something edible, or sealed with dry nitrogen. Maybe food grade
silicone under vacuum. This is easier than it sounds although a hole in
the floor is probably in order (or work on the stairways). 3m long tubes
are hard to maneouver ;-)
