I soak overnight before sowing in modules before sowing indoors. I don't plant them out until early June ... the leaves will turn white and they will stop growing if exposed to temps less than the low teens.

I too soak overnight and wouldn’t risk planting out until any chance of frost is over! Been caught out before that way but I do find they germinate well and grow quickly.
I suspect a sheltered Parisian suburb is generally a lot warmer than most of the UK in April and May. Certainly never put mine outside in the Belgian garden before mid May and then in a sunny, sheltered spot.
