I have one of those! You can put a mess of herbs in those things.
I live in the very humid midsouth. I cannot tie herbs in a bundle and hang them in the shade to dry. They mildew. Uck! My house also is humid, so I haven't tried it inside either.
I do have a
greenhouse. I load it up and hang it in there. I can now dry herbs successfully!
This year I am trying to dehydrate Elderberrys.
Here they are after 2 sunny days. They are halfway there.
Keeping the stem on them has slowed down the process. I've now stripped the berries off the stem. I hope they finish up tomorrow.
Anything that you dehydrate will finish faster if you can strip the leaf off any fleshy stems. For example, there is an amazing amount of liquid in kale stems.
