I dehydrate herbs using my microwave but I have to be careful because they will catch on fire it I use to high of a heat or leave them in to long. I have thyme, sage, rosemary, oregano, and chives. I was happy to learn that the older my clump of chives got the bigger around the foliage got. It now is the right size for drying.
Thank you Tkhooper. My microwave has only cook and defrost settings though. It is an old one. Welcome here!
