I have an earth tube. Mold is only a problem if the tubes are
inaccessible. Our system uses 30" well tile going down 10' to a
concrete manhole. Heavier reinforced well tile goes horizontal
for 15' to another manhole. From that manhole the cool air
travels to the house in three 8" PVC pipes to the small basement
under the kitchen. A person can go down into the concrete part
of the system and clean it out, and since the PVC tubes are
accessible at both ends, they can be cleaned by pulling brushes
through with rope.

Got one of them, too. Does a dandy job of keeping the attached
greenhouse purged of hot air during the summer.
