sprouting sweets and saving squash seeds

Today, I finally remembered to bring my small (finger-sized) sweet potatoes upstairs to see if the warmer temperature will get them to sprout. (I left the big ones downstairs to keep for eating.) I'd like to get the sweet potatoes to sprout soon. They start off slow.

Also, I roasted a nice buttercup squash from my local CSA and couldn't resist saving a few of the fat seeds. It is a nice variety with thick orange flesh that tasted great and kept very well until now. Even though squashes do cross pollinate, I think ones grown on a farm have a good chance of being pollinated by the same variety. But if they did cross pollinate, it will be fun to see what I get. I'll try a couple plants and see what they produce.
