The seedlings are in little 3" pots, in a plastic propagator on the windowsill of our spare bedroom - directly above the radiator. (Notice the pieces of old carpet-tile protecting the paintwork).
The first of these seeds germinated 8 days after sowing, which I think is pretty good considering they had no artificial heat apart from the central heating radiator (daytime only!)
Here are some photos of the newborn babies...
By the way, the light brown object by the base of the bigger of the two seedlings is not the seed-casing; it's actually a tiny pebble in the compost, which the seedling is shoving aside.
My concern for the next couple of weeks will be that I may not be able to provide them with enough light to prevent them going leggy. On days when I'm at home I often find myself transferring the propagators to the other side of the house at lunchtime, so that I can maximise their opportunity to get direct sunlight.
