Newby to the forums and need advice on a new humidor

Welcome to the greatest place on earth.

I have a few questions. What type of humidifaction are you using? How do you know it is not holding humidty? Have you salt tested your hydro lately? You maybe able to just put a little bit of tape around the inside edge of the top and it may be snug also.

Maybe take a pic or two and post those so we know what it looks like.
