~80% rh?!?!

[Old Smokey]

Damn Bob, sounds like your smokes have entered the Twilight Zone. I think if it was me, I would start over with fresh Bovidas and get rid of the Boveda Balloons. What do you store your aging cigars in? How many cigars are you talking about?
From what I have read, consistent Rh and Temp is what is needed to properly age cigars. If your cigars have been in 78Rh for several weeks, I would NOT try to flash dry them. I would put them in a sealed tupper with no added humidification and burp it at least once a week to let over humidified air out and slowly let them drop to desired Rh. I also would NOT intentionally expose to extreme Tejas heat. As with EVERYTHING cigars, slow and patient is the key. When they get close to your desired Rh, put some fresh 65 Bovedas in the container. Those BIG 320g Boverdas might be the ticket, so order a couple of extras. That's all I can think of to get your cigars back in order. You are probably looking at 3 months before they are where they need to be.

Someone may chime in with a better way!
