they improved the dutch strains, not vice versa. They took those genetics and made em better. I bet the Blue Meanie is better than the UK Cheese, lol. Maybe it causes arguements cause some just don't believe the statement, Dutch is not as good as US genetics, unless the US has improved the Dutch genetics. And yea, when you don't have proof, it always falls back to the hoarded cuts, lol. No offense bro, just an honest personal observation
Do you really believe some part of the world "has better genetics" than any other part? Seeds and clones are not so hard to transport, you know.
The truth is there are many many good plants grown everywhere, different strains for different tastes and different markets. No plant is so exceptional as to be everyone's best. If OG was something that stands head and shoulders above the rest, it would be everywhere, but it's just a great plant that became a local hype. Fortunately, not global.
