New Tupperdor Questions

Newb post, so please bear with me...

Ok, so I started a tupperdor a few days ago. It''ll hold about 125-150 cigars I bet. I got a hygrometer and the humidifying gel beads in a can to get it at 65%. I seasoned the 'dor with half an empty box in it. After calibrating my hygrometer I placed that inside. It was reading in about the 78-80% range, but I read you want it a little high before you add sticks. So when it held constant, I added about the 5 cigars I have on hand. The percentage dropped to 76%, but that's still in the high end of the optimal range and I want to get it down. How can I do this? I figured more cigars would soak some of it up, but I'm a college student and can only get a couple a week. I guess if I could score some more empty boxes to add it would help, too.

I also have one more question. If I can't find somewhere to put it that may be at like 78 degrees for part of the day, is this bad? I know about beetles and all, but beetles aside, if I can't find somewhere cooler will my cigars suffer?

the best place would probably be a dark closet. that way the sun doesnt get to them (BAD!) and closet would be cooler than being out in the open room.

Does anyone know roughly how much a 10 gallon tupperdor carry?
