I really want to start some photoperiods but I I don't know if it's convenient to grow them outside where the natural daylight period lasts around 10 hours and won't be 13 or so until feb, climate conditions other than daylight lenght are under control. Would they be triggered into flower really early if I start them now? Thanks in advance.
ya it would, photoperiods need more than 12 hours to be in vegetative mode. anything less than that will send it to flower. What you could do is grow it in a pod and move it inside in the afternoon so that it can take move forward. Once the season has changed than you can plant it outside in dirt. However, be ready to have a big massive plant because the plant won't go into flower until the season changes. So, you are bettter off waiting
