About two weeks ago, we had a nice 50-degree day and I was messing around with my makeshift greenhouse and thought I'd throw a couple kale seeds in there to see what would happen. Today, I cleared off the snow and pulled up a window to see what was going on and low and behold, there were kale sprouts! I was shocked. They got a good drink and I'll just bet I'll be eating kale in about a month. Kale loves cold weather. The temp under the storm windows on a sunny day is about 50 -- perfect growing temps for kale. Fun stuff.
