Other than the humidity. I am unsure if the former owners had air conditioning, but I don't believe that they did. I am unable to get ahold of former owners so I don't know what they did. The finished part of our basement down below is very moist and then outside of the room that is our biggest problem on the soil is all moldy. Also, in the last two days since we got the dehydrator we are dumping 30 liters every 12 hours. And that seems like a lot for me.
