Jon,

The air inside your system WILL contain some amount of moisture.  This 
moisture will "sweat" or condense with changes in outside tempratures. 
Unless the air is evacuated or nitrogen inserted into a sealed container, I 
think you may still have problems.

Best Wishes,
Jerry Payton

  Hi

  I am going to close the system inside, so the air is going to be
  resanable dry. However the sand I got might not be so dry, since I got
  it from outside and it is coverd in snow. I am going to let it dry
  (inside) for few days, at least until I have the weather to put my
  geophone underground.

  Regards.
