I didn't think I was quite at the 3 week mark until I looked at my calendar, time goes quick lol. I'm sure they have a little stretch in em but not that much. I mainly put the trellis up so when they do bud up they won't fall over. My gsc had to have every branch tied up so it wouldn't topple over but than again she was topped 5 times and almost 4 feet tall lol. But I'm hoping these get some huge colas and wanna topple over lol.
