Well here's a thing.
Last night, after reading the replies, I had one more very close look at my container and there was no sign of any shoots. So I got an old 2" deep plastic tray (old, cleaned meat packaging), filled it with compost and planted 15 new seeds, just below the surface and didn't water this time.
I was going to throw the compost in the old container into the compost bin, but it was late and dark, so left it for the morning. This afternoon I went out to do it, and there's a tiny tomato shoot! It's slightly open, a bit like Emu's mouth (as in Rod Hull) and one centimetre tall. That appeared from nowhere in a matter of hours.
So, if the rest shortly appear, it looks like I'm going to have a surplus of tomato plants.
