Old School Genetics available on Alchimia

This committed marijuana seed bank has been performing breeding work for many years, and it’s a pioneer in the Spanish cannabis scene, and more specifically in the city of Barcelona, home of Oldman Green, Old School Genetics soul and breeder. Recognized by many as one of the first breeders to preserve genetics, his collection consists of a large number of strains selected between the end of the 80’s and all throughout the 90’s.

In the Home of the old Finest Strains

We are talking of real gems, true old school treasures such as UK Exodus Cheese 87, some of Soma Seeds’ original clones like Lavender, Buddha Sister or New York Diesel, and many 90’s Haze strains such as Kali Mist pre-2000, Nevilles Haze or Super Silver Haze 98. In addition, and thanks to some friends, this genetic pool has increased and now allows him to work with highly popular genetics from Spain, such as Super Skunk 96 “La Joya Cut”, Critical Mass “Bilbo Cut”, Jamaican Blueberry, Tijuana, and many more.

Oldman Green is also a great lover of pure or landrace strains, and his collection bears witness to this; from Sativa genetics native to Africa, South America and Asia to Indica varieties with a great medicinal value from Afghanistan. It is known that he has a very good relationship with some of the most important breeders in the cannabis scene, such as Karma Genetics, Skunk VA, GG Strains, Professor P, or Symbiotic Genetics, which enables him to harness a large number of original strains from United States and to establish collaborations with many of these renowned breeders.

Oldies Never Die Series

From the end of the 90’s, Oldman Green has kept a large number of strains that are very difficult to find today, since many seed banks lost some of their creations due to legal problems or because some of their most valued genetics have eventually disappeared. Fortunately, many of these old school plants are still alive, such as White Widow, Great White Shark, Sensi Star, Lavender, Buddha Sister, Kali Mist, AK 47, Super Silver Haze, Chronic, Exodus Cheese 87, Northern Lights #5, Blueberry, Super Skunk, and many others, which will be offered by Alchimiaweb gradually. Currently, this series consists of both regular and feminized seeds. We have chosen some of them for our community:

  • Old Red Sour: Sour Diesel IBL x Jamaican Blueberry x Red Khyber
  • Old Widow 90’s: White Widow 90’s
  • Oldman's Silver Haze 98: Super Silver Haze 98
  • Strawberry Mist: Kali Mist pre-2000 x Tijuana Cut
  • OSG Cheese: UK Exodus Cheese 87 x Old Widow
