When done properly, it shouldn't smell. Another idea for you would be lasagne gardening. You layer cardboard, newspaper, and organic material to make a raised bed that breaks down and feeds your plants as they grow. No hoeing or digging required. Here is one of the many sites that describes it.http://ourgardengang.tripod.com/lasagna_gardening.htm
I have been eyeing this food dehydrator. It folds flat for storage and uses no electricity, and it keeps the bugs off. You can also use it for sprouting. http://www.wheatgrasskits.com/foodpantrie.htm?gclid=CMXH3cbfm6ICFQ0hDQodf0VkzA
While looking through the dolar bins, I found two collapsable food covers and thought that maybe I could use them to make one. At first I thought I would put a zipper between them but thought it would tip everything to one side while I was closing it. I have sewn a thin eyelet to the bottm of one, inverted the second, sandwiching the eyelet between them. This gives me two tiers. I then topstitched a zipper on the only part that does not have a coiled wire on the side and slit it open at each tier. Granted i cant fit a tray in, so I have to hand place each item. I left the zipper long at the top as I hope to add another tier. If I can't find another then I will trim it. I think it is handy for a $2. dehydrator.
Thank you so much for the links.
You did a great job!!!!!
