It’s no absolute, for sure - for example last year neither male Tirah was ever taller than several of the girls. And out of my Waziri repros, the lone male is in 3rd place out of 5 height-wise, and close to a foot shorter than the biggest girl.That males are taller to pollenate better is bro science imo.
I will say in my admittedly small sample size that the males have tended to show more space between nodes. But at the end of the day, until I see a plant’s junk show up I’m not sophisticated enough to make the call.
