ExactlySounds like a risk of moldy pipes.
I use a condensate pump and run a hose from the dehumidifier to the pump opening and the run a clear tube from the pump to a slop sink in the basement so I never have to empty the bucket ever.I have a converted garage in Atlanta, now an un-conditioned room with walls. We run a dehumidifier in there and have to empty it 2-3 times a day. Definitely wouldn't leave the Petes out there.
Perhaps this ^^^ I think we'd all love to know boveda life spans for this through SC summers. I DO keep beater pipes in garage and screen porch in FL humidity. Even some fav cobs and new (budget line) Kawoodies let alone other briars DON'T get stored out there though. Loose stems and souring briar was my visible & sensory garage culprit. Perhaps a mini-split with minimal insulation ... but cost(s) of course.I would never leave pipes in a place like that. I would grab a boveda humidor bag and a 49 percent music instrument boveda pack and place however many pipes fit into that bag with the humidity pack. 40 to 60 percent humidity is optimal for wood instruments so should be good for pipes.
I do that in the basement but the wife likes to use the water for her plants! She needs to grow me some tobacco.I use a condensate pump and run a hose from the dehumidifier to the pump opening and the run a clear tube from the pump to a slop sink in the basement so I never have to empty the bucket ever.
