@Iluviaporos - I think it's useful to know about green potatoes because I actually grow my own every year. I've been keeping them in the ground while waiting to eat them, because I thought that helped them keep better.
But, I haven't been completely vigilant about keeping them completely covered, particularly after a rain. I didn't realize it was sunshine that caused them to go green.
I might also have to keep them in a darker area in the kitchen, as they probably get exposed to too much light in there as well.
This is probably going to keep me from losing so much of my potato crop.
