I got 22 jugs done up today, a variety of things...mixed morning glories, poppies, alyssum, lovage, basil, cabbage, broccoli, kale, mustard, brussels sprouts, escarole (thanks
@Nyboy 
), lettuce, some pink rose seeds I got from hips collected in the native garden at the Andy Griffith museum in TN, 2 types of tomatoes which I am starting at the same time as my indoor flat of tomatoes for comparison...and some other stuff I can't remember right now. I may do a few more of flowers as I get my hands on some more jugs.
LOL, I can't tell you how many jugs I had to un-tape because I got in a hurry and taped them up, forgetting to cover the seeds with a little soil first.
Nothing I planted needed cold stratification, or else I should have had those done months ago. Still plenty of time to plant other more tender seedlings though. I'm excited to see how this works out. Everything I've read and heard says the seedlings will be tougher and more adaptable to transplanting, having experienced normal weather and not having been babied, no hardening off needed. This will allow me to start a lot more stuff than I could possibly fit in flats in my sunroom.
They say you can start just about anything this way, although more tender plants should be started later and covered with a blanket if a freeze is expected. Now peppers are one thing I wouldn't wintersow. Those need more heat to get going.
I have a little more left in the bag of potting soil, a 2 cu. ft bag of MG moisture control potting soil. I'm guessing I could get 30 milk jugs per bag then. They said it doesn't have to be sterile potting soil under these conditions either (although if you use garden soil/compost, make sure it isn't full of weed seeds.)
Have you had anything sprouting yet,
