They'll be absolutely fine, as phil said put them somewhere light but preferably not too warm and let them sprout. Light is the important part here, you don't want those long white sprouts one finds on the potato that managed to roll under the cooker last month!
So. it was 2 weeks, and I had been only glancing at them on lower shelf by window - seeing nothing. Picked 'em up to check before posting lack of success ... they are covered with tiny green sprouts!
Now what do I do?? Also somewhat worried about the little bit of scab that affected the reds. When I removed from fridge, I rinsed them all together because their skins were slightly desiccated from storage, and my house is very dry.
Gonna plant in a new area and don't wish to spread scab. At least we know it worked, but potato sets are inexpensive, and I wouldn't mind tossing them. Would only keep perfect ones next year.
Thanks for the advice, you all.
