ok to go 12/12 ?

Hi guys,
(Firstly I'll apologise for the poor quality of the image )


This is my second grow; the first being a disastrous two males from two seeds.

This time 3/4 seeds germinated (Northern Lights).

These plants are approx 7 weeks old and between 8" and 9" tall.

I have just found out that I am to be going away for three weeks in about 11 weeks.
As I am new to this - I was wondering...

If you think it's ok to go 12/12?
How many weeks it would take (roughly ) to harvest after I start the 12/12?

Or am I in trouble?

Thanks

Northern Lights being an indica dominant strain, I would guess you would harvest in 8-9weeks if you switched now, and whilst not ideal it would seem you have no choice but to do so now, good luck! also plants look nice.

agree ^^^ Flip now, they should be done in 8-10 weeks. Give you a week or two to dry and start curing.

Thanks for the feedback guys.
Well, gotta make the best of a bad thing.

At least now I know it's possible
