Light cycle for outdoor plants

what light/dark cycke should i use if i am germinating for an outdoor grow? something to mimic what itis outside? right now we are at 13.5 light/10.5 dark - should i mimic that or use longer?

Most growers will start young plants at 18 hours of light per day. Photoperiod cannabis is capable of flowering with less than 14 hours of light per day. Read about ‘hardening off’ for information about transitioning an indoor plant to outdoors.
