I have recently gotten an email from a man who wants to build a SB mushroom farm. He would like to know if it is a problem that the INTERIOR of the building has a humidity level of 75-90%.
I usually prefer to use breathable earth plasters (or lime), but I am wondering if this would be a good case to apply a WATERPROOF (cement? latex paint?) plaster to the interior of the building to avoid excess humidity in the walls.
Any thoughts/suggestions?
