Considering the cost and difficulties in setting separate places for vegetating and flowering, i decided to use a constant 13/11 lighting schedule for the entire grow both for vegetating and flowering.
It's said that 10 or more hours of dark period is good for flowering. Sativas are said to need more dark hours than indicas do. Some sativas require more than 14 hours of darkness in order to start flowering. Some indicas flower with as few as 10 dark hours.
12/12 is a well known method, preferred by many (criticized by many too though). With this method, plants don't get much bushy and said to have flowers mainly on the main stem nodes. (

13/11 is also used by many for flowering stage. So if 12/12 can be ok for vegetating then 13/11 can do better. Well, for flowering, considering the fact that the most of the plants in the room are indica dominant, 11 hours could do it.
I don't know let's see. It is the reality's limitations which forces this to happen, it can't be labeled as one of my other bad decisions anyway
