probably a little of each ... I still doubt the seedlings like 'scootching' ... as far as I know, hybrid vigor shows itself in every facet of development ... faster, bigger, stronger, etc. ... the first 'NorCal Daddy's Girl' blew me away, she just grew 'better' than my others, best way I can describe it ... I would assume that is characteristic of 'hybrid vigor' ... I'll be in Illinois corn country in a couple weeks, I'll ask my farmer buddies ... they explained the hybridized corn programs to me, was very enlightening to this old city boy ... again, good work, Treetops, I'm very interested how these turn out, as I was preparing for the same hybrid ... I think you have a potential 'Cup-Winner' there :thumbsup:
