It's very nice to rescue some truths of things that could go down as urban myths, most deffo hollow branches mean bigger specimens within the same strain.
I'm not sure if also means better, because there are situations, such very small rooms, where a shorter pheno is preferred. That just happened with my two phenos of Aliendawg f2, a friend chose the non-hollow stem because it adapted much better to a little home made box, then he put the hollow pheno outdoors. I like better the hollow one, but just a question of personal taste, the other gives a nice and strong high too.
Those pics are talking, Ent, hope my AKf2 also show that same trait. A friend is sowing them now, 8 out of 8 opened like boiled clams in 24 hours.
Ps. Hey peeps, respect for number 4!!!
