This question is a direct consequence of the When to harvest wild hops? one. I have heard about various techniques to do it: sun-drying, warm rooms plus paper bags to capture their humidity, ovens etc. What's your suggestion? If you suggest an oven, can you specify the ideal temperature and drying time?
Update I have built a dehydrator with a very small amount of money. Basically it is composed by four disconnected wooden frames onto which I have nailed a metal mosquito net. It works like a charm!
