I wouldn't be sowing stocks until spring, and only then when temperatures are warming up - I think I'm right in saying they need temperatures of around 20C to germinate so a heated propagator would be helpful if you're trying to get an early start.
I only grow the night scented stocks and direct sow them in the late spring where I want them to flower.
