light change advice

hi iv got 6 week old superskunk, i just wanna no if there ready to change the light cycle to 12/12. i wanna get a descent harvest of them, r the branches strong enough to support the buds. i have about3 or 4 foot of grow room left, and iv been told they double and some triple in size when in the flowering stage. heres some pics, any advice would be appreciated.

They look good mate, and i recon they will fill that area out nicely. They certainly can double in size and more.

your good to switch to 12/12 mate them ladys will fill out nice

you can flip them anytime, their ready although personally i'd go for larger pots coz they look pretty big and i think they may outgrow the pots they're in . btw that last pic shows a little leaf cupping, its quite often a result of heat stress. and they can double or triple in size.

oh ya your good any time
