You can bend a plant even until the main stem bends or 'folds' in half.....you can even crush a stem...as long as you dont break or sever the life lines, MJ plants will keep on growing.

Most stalks are actually hollow in the middle at some point anyhow.

As for bending, take either a shoe string or a twisty tie and tie it under the second node from your top.

Poke or drill a small hole in your container edge.

Run the twisty tie thru there...

Tie her down just until she bends then do it about another inch or so a day.

Within a week, she should be bent over compeltely.

Her main stalk will then begin to twist and swell all over. This will accelerate the feeding of the secondary grow shoots...which is what you want.

But again, since you are in flower now....I cant honestly say I have any experience in tieing down during flower.

I would personally yank her our of flower and go another 30 days with bending and lighting....

If not, i would just leave her as she is and hope for the best...but you will need some good lights for optimal bud growth.

You have any funds for another light?
