First batch of tomatoes growing well

First batch growing well, originally uploaded by mike1727.

They're growing nicely, there were only a couple of seeds which didn't germinate. The weather's looking good for the weekend, sunny and temperatures in the mid teens C- so not too much of a shock for the seedlings moving from a warm house.
That leaves me room for another batch, which will give me a longer harvesting season and some spare plants to swap.
