Chemdawg has developed an incredible reputation in the US where it is said to be the male parent line of OG Kush, Sour Diesel and Headband. It is a sativa-dominant strain that exudes a powerful perfume which combines the aromas of pineapple with diesel/petrol.

Trainwreck is another strain from Humboldt Seed Organization with its roots firmly planted in the Californian sunshine. It's a sativa-dominant strain hailing from Arcata in Humboldt County and is said to have derived its name from a train crash in those parts.
