people say it because the guy that runs GHSC (Arjan) is a lying scumbag that has contradicted himself more times, on more issues, than any single person in the business. Arjan is a marketing machine, a great marketing machine to be sure. but GHSC went downhill ever since they lost the main breeders (Shanti and Neville, who went on to start Mr. Nice Seeds).
and Monkey, if you grow their products, and you enjoy the results, then thats what works for you, and that's awesome. but there are many many people out there and on these and other forums that would respectfully agree to disagree with you.
