No I have not! When I started drying herbs from my garden I just placed them on a plate for a couple days and I just stuck to this technique. Using a dehydrator can be quite nice because you can choose (if yours allows it) optimal temperature to evaporate moisture and keep in the flavour.
Have you tried it yourself?
I will add links to this post on how to use dehydrators and what dehydrators you can use to dry your herbs. Thanks for the idea!
I don't have a dehydrator. I'm hoping for a company to send me one :)
A friend of mine told me he used some sort of Crock Pot used to warm dips, I think he said it was called the Little Dipper or something. I don't what temperature it heats up to, but that may be worth trying out too!
