My OH grows them. He usually starts sowing seeds at Christmas in a propagator under lights. The plants are currently about 6-8 inches tall. They go into a heated greenhouse about April and then stay in there. Once the frosts have passed, the greenhouse isn't heated and they are watered daily, and they also get a feed with something called Chilli Focus weekly or monthly (not sure which).
He gets such a large crop of different chillis that we give them away, keep some for seed harvesting.
You can grow indoors, but they do need heat to produce chillis.
