I’m about to flip my first gmo tomorrow. She’s about 20” tall. I usually flip plants at 27”. That includes flipping the glue at 27” and it still ends up about 48” right where I need it without supercropping. I don’t seem to get no where near the stretch as most ppl. I figure it’s because I try to veg them so big. But with the gmo’s reputation, I ain’t taking no chances!
