I'll tell ya how I do it lol. I have to sleep with a fan just for the noise so I lay em out where it blows on em at night and it usually does the trick in about 5 days. I had some really big roots a few weeks back and I was gettin scared they were gonna rot so I layed them out for a about four days to let the skin dry slow then stuck em in my dehydrater. Worked just fine. They were to big to set the lid down on em so I placed a cup in the middle for a tier and wrapped saran wrap around the outside to close it off.
