Sumo Seeds crossbred an Old Afghani ( Afghanistan Indica heritage) with their Honey rock ( Super Widow x Swazi Poison) they called this offspring Sweet Afghani. Sumo Seeds then further crossed it with a beautiful Sour diesel to create the Sweet Harlem Diesel. A nice mix of citrus and diesel aroma. A nice hybrid of indica and sativa genetics. You will get the best of both worlds. A great strain to spark your creativity. With a heritage from the United States Sumo Seeds couldn't not mention her origin. So they choose to name her Sweet Harlem Diesel with a slight reference to The Netherlands where they further developed this strain.
