I've heard all the rumors, Arjan (the owner of GHS) is an egocentric fella, that he can't even grow a plant, that GHS lost all their genetics to Shantibaba, that GHS is the devil on Earth.
Still, I've been using a lot of feminized seeds from GHS (SSH, White Rhino, White Widow, Alaskan Ice, Neville's Haze) and I have objectively concluded that they do deliver a good seed. I have never been let down and I really think that's what really matters here, if the company delivers what it promises. I don't care about the rest. As long as my plant doesn't look like a stick in the mud, I'm happy.
I'm not saying GHS is great or that it's staff is on the honor roll. I'm not a sales whore. I just like to set the score straight. The company has yet to let me down.
