They look ready to me. I've no idea how much they'll stretch after the flip, but with limited headroom, it's better to be safe than sorry, imo. I had to yank one of my ladies recently since she more than doubled in height the first three weeks of 12/12...just had no lateral space to lst her. It was a real surprise, since I'd grown the strain many years ago, but I was working in a seven foot high closet then and I suppose I just thought I had timed it right so I could keep her under control, but I was wrong. Three feet of headroom requires entirely different tactics if you want to avoid burning your buds, that's the lesson I learned.
