egg carton jiffy starters

I'm not terribly thrilled with the results of my egg carton planter. It did give me instant, free extra sprouting space. But this morning, as I transferred the little spudlings into a bigger planter, I discovered that their roots had grown firmly attached to the soggy bottom of the egg carton. I'm not completely convinced I didn't damage them trying to get them out.

Have I mentioned that it's still snowing here? My house is slowly filling with little window boxes perched beneath every available sunny spot. This is the first year I've tried to grow any kind of green plants in this ridiculous climate. I'm debating whether to build some kind of plastic hoop house. I don't think our weather will ever be safe for things like tomatoes to be grown outside.

I'm terrible at telling plants apart, especially when small, and we don't have any craft or popsicle sticks. But we do have wooden clothespins, so I sacrificed a couple today to serve as labels.
