Old Red Sour from Old School Genetics is a super hybrid between Sour Diesel IBL x Jamaican Blueberry x Afghan Red Khyber. Oldman Green has used Sour Diesel IBL’s famous clone “Riri cut” and a Jamaican Blueberry x Red Khyber male, a very special hybrid of his own creation. This male contributes with a better ramification and a more moderate stretching than the female Sour Diesel IBL.

It is a plant with a fast development that maintains the rigidity throughout its entire life cycle. This strain inherits a ramified structure from the Jamaican Blueberry x Red Khybe male, which acts as a fairly Indica plant, and results in a well-developed leafy branches with many internodes.

Oldman Green has successfully combined very distant aromatic nuances, such as an intense fuel flavour with an earthy Sour Diesel IBL aftertaste and a particular forest fruit and citric hints of two distinguished landraces. These landrace varieties, very much loved in Spain, are Jamaican Blueberry by Cannabiogen and Red Khyber by Alex La Mano Negra (R.I.P), a legendary cannabis breeder in Spain.

Old Red Sour was awarded 1st Prize Sativa Category in the 2018 ICMAG Cup Barcelona.

Perfect strain for cannabis seed collectors and legally-operating extraction artists looking to take advantage of her resin production and unique terpene profile.
