I always start my seeds off in mid Feb - it works well for me. They are then normally ready to prick out into trays and go into my unheated GH the weekend the clocks change ....which then means it is light enough for me to visit them morning and evening before and after work.
If i leave it til later i find that I don't get flowers til mid August - and I like to have them a bit earlier than that.
so horses for courses - you have to find what works for you - and you can only do that by trying different things each year.
