Cello question...

I have been aging Anejo cigars since they came out and have purchased many boxes over the years. I've heard of the mold problem in the past, but have never experienced a problem with any of mine. I put the boxes in the cabinet and that's that. I've yet to have a mold issue.
I think the main thing to worry about is the humidity in your humi's. If your not storing cigars at 70+ RH, you should be fine.
