1st time planting potatoes

[jnunez918]

I just ordered seed potatoes. I bought some potatoes a couple months ago from an organic store. They are now starting to sprout. How will the ones delivered in fall have enough time to sprout? Or do certified seed potatoes have to actually sprout before planting? Also what is the best method to encourage sprouting, I read dark pantry, warm windowsill, I'm confused.
