Hi classmates, I posted this, too, in the ATP section because I am definitely interested to hear if David has a solution to it. But I would also be very interested and grateful to hear from other people living in high humidity locations how you solve the issue of to drying your herbs under such circumstances. We live in a very humid climate in Northern Germany (relatively maritime, temperate, lots of bogs and “heavy soil”). After 3 relieving “dry” years this year, again, is very humid with relative humidities between 70% and 100% at 65°F (18°C). We don´t have air conditioning or air driers, so our indoor humidity has spiked to an 80%, too. I always use a dehydrator for herb drying that uses room air, pushed through a filter, at 95°F (35°C)to dry my herbs. Even after 7 full days of drying this year the herbs are still “half way there” and soft to the touch. In recent years, they were dry and crispy after 3 to 4 days. In former years (not as humid as this year though) I´ve gone up to dry at 105°F (40°C), which has only slightly helped. Since I am planting many of the herbs I use myself (yes, much rain is great for that ;-), I´d hate to end up buying them, and some of them are hardly available on the market anyway. Also, using up so much electricity in drying them for more than a full week is really upsetting me in terms of being considerate with the use of electricity (well, and it is pretty costly in the end, too). I was wondering if anyone of you lived in a similarly humid location and would be willing to share your tips and herb drying process with me. Thanks a lot!

Hello- I, too, live in a very humid area. I would not recommend the following ideas for commercial use, as they certainly would not meet any standards for hygiene or safe practices. However, when I have had a big harvest of herbs, like passionflower, which I am going to use for myself, I have put a clean sheet on the bed in an upstairs bedroom, and turned on air fans. I suppose I could also have hung them up there, but I had a lot, and the bed method seemed easier. This usually works. One year it did not, and I had to throw that batch out when they started to mold. So I took a clean sheet and put it in my car, and put the herbs on that. This method worked very well, almost too well, as it got pretty hot inside, so at one point I opened a window a little bit. The herbs dried very well.
