10 or more hours of uninterrupted darkness will cause flower phase to begin. So, it will almost certainly bloom with 14 hours of darkness.

VPD and DLI could inform a bit if you want to make an educated guess. 10hours a day will euate to a different DLI depending on region. As long as it's 22DLI or higher, should produce okay buds. (40ish DLI being a soft max). Hopefully you have strong sun in your region. google "daily light integral map" and your country or region> It's often available info without doing the math yourself.
