Thanks for the rep,
@Hotfire!
Both grows I've done of SS have the plant being roughly 3 feet high. The breeder says 50-70cm which seems pretty short to me. TBH, there's a lot of factors that will determine how tall yours will go.
The trellis I used consists of these poles you stick in the ground, then clip these crossbars to. That allows for placing the bars wherever you need them. I'd post a pic if I could find one that was clear enough. The limiting factor on the trellis height is the length of the poles
I started trellising some time early in veg. I didn't want to wait until the branch hardened. I wanted to get it while it was still flexy. I placed the cross bar over branches to force them further out. My goal was to have all tops be the same height.
