You were very polite and wells spoken, so here's some advice, write an intro post and give us a few details about you and your smoking habits. Great buy by the way. That was Tommy's last humidor made for LGC before he passed last year. Using the built in humidifier is fine as FunkyCold5 stated. Don't use the tubes unless you need a little extra humidity. They work well on smaller humidors, but not one this size. Or.. Take chefchris's advise.

PS: Fill out your profile. Gives a better chance to get to know you. Post the smokes you like, wish list, ect.
