That's an interesting approach! I've dug and cured in the warmth following tradition - I put the tubers in a box and place that in a car parked in the sun, so the space is warm and humid. Last year, things turned cooler, so I wasn't happy with the temps I could achieve during curing but the sweets seemed fine.
I have had problems in the past with tubers splitting when it is really wet in late summer. Hope you and your crop have done OK, Susan, with Hurricane Florence!
