This is the type of bad information sources like High Times provides. Truth is....we don't know what OG is because the guys who were originally involved in the creation of it aren't talking after the DEA started busting Overgrow affiliates in 2006. They're too afraid to talk.
Chem Dawg may be a part of the genetics, but the truth was lost in 2006 when Overgrow shut down and the original breeders went into hiding. Grow forums have been pure shit since 2006. Overgrow was better than every forum on the internet combined. It's a travesty that it's no longer around. It blew every other source of information away.
No offense, but I was on OverGrow. While yes, we mailed beans to each other, and some of us swapped clones and the best phenos we were working on (I am sure many more in Cali were swapping plants, I was in Tennessee and didn't have that luxury...), there was no super secret strain we (at least any of the groups I swapped/bred with) were mailing around the world for people to work on.
We were happy to share anything and everything.
Yes, "OG Kush" was going around on OverGrow back then... but guess what? So were 70 other strains and phenos. It wasn't some secret project designed by a 20-man think tank.
Just like any other strain, it started as a lucky cross in someone's grow room.
I consider my strain about as bona fide as you can get these days. It hasn't been altered in the 7 years it has been in my possession, and was given to me by someone I have trusted for over a decade. And guess what... even I'm not sure if it's an original "OG Kush"...
Truth is... no one knows anymore. Weed is now legal/decrimed/recreational in so many states, no one is afraid to talk about it anymore. No one is hiding any secrets Leo da Vinci style, and chances are, no one is ever going to know.
But I will say I have smoked Chemdawg, and they do share a lot in common. The plant structure, the smell, and buds... they all share a whole lotta similarities.
But damn dude. No one's too afraid to talk. It's just lost info. It's a great urban legend, and every good strain needs a good story...
