Windowsill gardening in an abbreviated season

During my last two long stays in the US with my fiancee, I got the gardening bug, bad. But right now, I’m over here in Groningen and not over there in middle Tennessee. And I’m moving out in May, so it’s not like I can complete a growing season here. The solution: windowsill gardening with a sharply abbreviated season.
I have bought a bunch of seeds, a propagator, potting soil and some inner pots (I had some outer pots left) and have got on with preparing/soaking seeds and planting them.
The whole project assumes that no plants are going to be planted outside (except one), so I have decided to ignore the start date instructions on the packaging; plants are going to be sown now or next week, in standard potting soil, using the same procedure for each of them, and we’ll see what comes up and what will be ready to eat in the next few weeks. The one good thing about not having a real growing season anyway, and doing this for the first time, is that I can make mistakes and not regret them – all that will be lost is 25 Euros worth of supplies. Whatever I learn from the experience will be usefull next year, when I will be in the US and doing real gardening and farming.

I am going to grow:
Cayenne peppers
Leek (as a sprouting vegetable)
Red cabbage (as a sprouting vegetable)
Spring onions
Fennel (as a herb)
Celery (as a herb)
Spring spinach (this is the one that’s going to go into the ground as it is a fast growing variety that should be ready to eat within two months)
Basil (not planted yet as I ran out of pots).

If all this stuff just grows as I hope for, this will probably be the only post about the windowsill gardening project. If anything interesting goes wrong, though, I’ll let everybody know.
