A lot of misinformation in this thread and even a quote from leafly. Leafly is so wrong I can't imagine where they get their info.
The clone only skywalker og is not kosher kush and it has absolutely nothing to do with dp skywalker, it's a pure og released by a warehouse grower in LA named Luke who's nickname was skywalker. There were two cuts released labeled skywalker, the original one is a sativa dominant og that looks amazing, I'd say it's the best looking og for sure.
DNA might have selfed the real cut I dunno but even so the phenos from the seeds aren't gonna be exactly the same as the real thing and this might be the reason there's so many fake skywalkers now.
I don't know much about the kosher kush and the story they give might even be made up who knows. The kosher kush is a good og with a very strong chemical smell.
The real skywalker og cut also goes by the g cut to seperate it from the fakes.
