I too know a number whom do this that said I don't know any that use 82º most I know of use a warmer temp than this. I too would second Deborahs comments and add that a know accurate thermometer should be included and given the price of accurate (slippery term I mean less than one degree error) and traceable to insure it is within that range. Sadly this is often a higher cost than most are willing/able to spend. The breeders I know of whom just use ambient temps have very good regulation and thermometers to insure the temps they use are constant and accurate.
