Spaceman I think the guy who is slicing the tube has the right idea. I have done a bit of work with the corrugated plastic drainage tube with the slits. They are designed to take moisture in not to let it out. Therefore you will get small puddles of condensate at the bottom of every ridge perfect little breeding grounds. You cannot guaranty that there will be a slit at the bottom at all times and it will need to be at the very bottom. If the air flowing through the tube is dry enough to not condense than the air entering your home will be so dry you will need to add humidifiers to your home. Molds are like bacteria there are thousands of them some are good many are not and they are incredibly resilient. If you absolutely have your heart set on earth tubes you need to find a way to routinely clean them. One way may be to build your self a powerful Ozone generator. Running ozone through the tubes once a day or once a week would likely keep things under control but the problem with molds are that it is the spoors dead or alive that cause the health effects so it is important not to let them grow to begin with. Ozone generators can be built cheaply with Neon light ballasts and glass plates. Google any of the sites that grow the “wonder herb J “ there will be instructions.

Subject: Re: [papercreters] Earth Tubes
You are right, and I would not recommend earthtubes for all places. Luckily I live in an area with low humidity, an annual average temperature that is comfortable, and great drainage. Not to mention low annual rainfall. With over 1,200 square feet of surface area in contact with the soil the inside temperature should be stable at 68 degrees even without the earth tubes, but I want to wring out every calorie I can. Tubing with precut slots is not very expensive and will drain well. There won't be any period of time that the tubes will be sealed, so no chance of moisture buildup and starting mold.
