BT,
I was very careful to allow the unit to drain any condensation as it was designed to do. I elevated the cedar floor by 1/4" and cut out around the rectangular pooling area in the back bottom corner of the cabinet and gave it about 1/2" around before the cedar lining, so it is elevated and held back from the moisture areas.
A pound of 65% beads is in the back but is 1" shy of the rear moisture channel so it is way clear . I also made sure the cabinet is level so if there was any condensation in the rear of the cabinet it could drain right down the back and out the bottom freely.
After about five days now the humidity is starting to stabilize around 64% and the temp is still steady at 63-64f . I am about to throw that off with a couple of singles trays. More pics to come.
I would avoid putting any loose smokes in direct line with the fan, I am planning on boxes up top and singles in the bottom, my singles trays will have a 2" air gap in front and behind them with the fans blowing up through that space, so the circulation of air should be drawn through the trays and not blown directly on the loose cigars. Also this circulation will only take place for a couple minutes a few times a day, just to move the air around and keep RH/temp uniform...in theory, that is woodworking helo mech theory so who knows.
I had a slight delay and rearranged a couple machines in the shop during this project.
see ya
