Being honest, we (we germinated loads in the office as a group) didn't put a huge amount of effort into it. We bought 3 covered seed trays, each with something like 36 peat plugs, and put 3 or 4 seeds into each. When more than one germinated, the smallest were pulled out. We kept them on the window sill, and then when they had established their second set of leaves, we took them home. I transferred mine into 5 inch deep pots, and put half on an indoor window sill, and half in our lean to / conservatory. If was pretty cold at the start, but that only made them hardy. They're all now getting on for 4 ft tall, and they've been topped off twice. As you say, I did get very lucky with the early sunny weather.
If you're germinating early, I don't see the need to get artificial light. They'll possibly grow too big too soon, and be weak stemmed. Just my opinion though, and this is the first year for a while that I've got it spot on.
