Longbottom Leaf

I am hoping someone can advise me how much stretch to expect in flower.

I have 2 female Longbottom Leaf grown from seed sown in the second week of our summer. They are over 4 ft now (130cm) - I topped them in a panic about 3 weeks ago - and should go into flower in the next few weeks (I have some indicas that are just starting to flower now).

As you can see from the pic if they grow much taller they will run out of camouflage so need to know how drastically I should bend them now lol

Let me get with breeder Loran and find out. Indoors they have low stretch, a 4 foot plant finishes around 5foot.
