Hungarians are pretty hardy chillies. I tend to get all my chillie varieties started in-doors in about August and then they go out side late October. Seedlings will do well under 8500K T8 lights for about 6 weeks. Sometimes August can be hard to do, especially if you have a cold house. I'v had mixed results with raising on a window sill but it can be done with more hardy varieties. They love early light and after about 8 weeks, repot to about a 10cm pot and put a heatpad under them. Makes them go nuts.
I should add, the main fruiting season if you're not in a glass house is late December, as long as your Hungarian has 30 or 40 leaves by then you'll generally get a good little crop. If you plant them in the ground in a sheltered but sunny spot, you'll get HEAPS.
One of my favourite eaters and nice and easy to grow.
