You can start to make pretty striking distinctions in the strains! I've defoliated much of the leaves blocking lower flowers. My Mango Tango x Sugar Black Rose cross is looking great next to the Pennywise that didn't herm. Love plant genetics, it is so fantastically interesting. One of the reasons why I like growing cannabis so much is seeing the variations among strains and looking at how traits are inherited (I may or may not be a scientist...)
