I think you're going to find japs just a little too thick for good drying at low temps. Freeze/dehydrate/freeze/dehydrate works good if you don't want to bump up the heat too much. -Jim ~~~~~~~ Just trying to give the unit a good work out, I knew that drying Jals would be about the hardest. If I can get it done with just a light bulb and a fan JohnT said that he believed that drying at 140F 'might have' killed germinatiion If I can get the job done at 120F and still have viable seeds that would be a plus... 120F is not that unusual in NM, TX, AZ and CAL. right?? Just a different thought L.B.
