They stretchy, would definitely recommend a screen or at least some training.
I fim'd the one and the two main colas were not strong enough to support the buds, so I've had to stake them up :/
The other one has just been tied over and the main cola stalk is nice and thick. With the training I've done the canopy is sitting at about 3 foot, without it it would be well over 4.
They're in 4L airpots with coco, I wanted to keep them small but still ended up with monsters
The TD is still dragging along, I don't mind the wait though.. Just hope it's worth it.
