I feel like this thread never really got a good answer as there seems to be a confusion between Kush and Og Kush. Kush strains are 100% Indica thus landrace strains that had been bred for their specific environments. The smell of kush is always pungent. The smell is thick and it stays in the room long after the jar has been closed and put away.Thick smelling like some of the incense you would smell at church. Kush can smell sweet and musky at the same time, while being earthy with hints of pine and sandalwood.
Kush is one of the oldest strains of cannabis that exists, native to the Hindu Kush mountains that run along the Afghanistan/Pakistan border. It’s the Indica that came from that region that is referred to as Kush.
On the other hand what we’ve all know and smoked as og kush is the brilliance of basically crossing the best sativa genetics with the best Indica Kush genetics. So in essence it’s not a put Kush strain. It’s a hybrid and it’s phenotypes can sometimes smell more on the lemony side, (Sativa terps) and sometimes more on the earthy Woody piney side (Indica Kush Terps) a lot depends on the environment as well that can kind of shift things around a bit. However when you have a mixture of them all you get the gasoline, pinesol
Smell which also in my opinion is a sign that the og kush is a bit chemed out. The old school legendary og kush smells pungently Musky, sweet and earthy with hints of pine when it’s properly flushed, high in resin content and cured properly. I’ve seen it smell more lemony pinesol when it’s not properly flushed right.
