obtaining seeds from cauliflower

[Jed Doelling]

I would like to collect seeds from cauliflower plants but I do not know how to 
make them flower and set seed.  Is there some special treatment that induces 
flowering?  Are they able to set seed after they form heads or only before?  Any
advice would be greatly appreciated. Thanks.
