This has all been very helpful...fb and I were just talking yesterday to try and start dehydrating.  Right now we buy everything already dried.  We have a dehydrater but it does not have a temperature control on it.  We thought that maybe if we stacked a bunch of them on top of each other and put the fruit and veggies on the top it would slow the heat down....is this correct thinking?  Our house has been under construction for the past couple of years so we haven't had much time to try dehydrating...we both have the fever really bad.  We stopped at the health food store on Saturday to get fruit to practice on.

Thanks again for all the great ideas....I think I'm qj hooked...what took me so long?
