I just purchased the rectangle humidifier available from this site for $14.95. I am very new with cigar smoking so please bear with me. Do I have to soak the sponge in distilled water? If so, what is the best way to do it. My humidor fits 75 cigars. It still isn't seasoned, I haven't installed the humidifier, and my order of 75+ cigars just came in. (Cigar.com very fast shipping) Please help. How long do I have before my cigars start drying? Thank you for your help.
