The slower you dry it the better. I would probably put them in boxes with a couple holes where air can run through, Just hang them in the box.
yes, you want air movement in the room, just not directly on the hanging plants.
I put mine right into paper bags, and they dont taste like bag... I dont think they absorb odor from things that are cardboard/ not imoi dont know why you would ever want to put them in a box!! lol, wouldnt that just absorb moisture faster? and make your babies taste like box lol
