how much would it take to harvest?

my first grow , el nino feminized . i switched to 12/12 2 weeks ago after 9 weeks of veg .
my question is how much do u think iy will take me till harvest?
growing in a autopot , cocos and ghe nutes , flushing every week ...
lightning is 2X 4100 lumen 2700 kelvin cfl lights.

Well the information on the strain sais 8-9 weeks so go for -9 weeks as a rough guideline, but you harvest when it's ready.

is it totally wrong to take cuttlings for cloning now?
and how can i find out if this strain is suitable for SOG?
sorry for constant questions

You find out by either searching, say using google etc, or you learn from experience. You can take cuttings anytime you like really, if in flowering, it will take long for them to start growing again but it is by no means out of the question.

thanks a lot for your quick answers.
