I was kinda stupid and bought a 50 dollar large humidor offline. The problem is the 'glass' top turned out to be a cheap sheet of plexi glass held on by four screws. I am thinking the top is leaking humidity like a demon so I have alot of trouble keep RH up. If there any kind of glue/caulk type material that will fix it or should I just spring for a better one. When I bought my current humidor I thought it was big enough then I started enjoying cigars more and more and the humidor seemed to shrink...
