My dryer vent is about 6" above the floor of my deck. I took two birdhouse gourds grown this year and laid them by the dryer vent. Guess what???? The seeds are rattling inside the smaller one. The large one should be dry in a couple of weeks. They have been under the vent for approx. four weeks. I use the dryer every Saturday (just about all day) and maybe once or twice during the week most of the time I don't use it all through the week. I think I will sit one of my apple gourds by the vent and see what happens.
