A lot has been said about the genetic lineages of ChemDawg, Sour and Kush, but not much has been said about where the cannabis seeds that Chemdog got during a Grateful Dead rock concert in the summer of 1991 came from. In this post we explain the history of the genetics of Chemdog, a key strain in well known varieties like Sour Diesel.


Chemdawg and Chemdog


ChemDog met Pbud and Joe Brand at a Deer Creek rock concert, a US band that played in the old Deer Creek amphitheater (now Klipsch Music Center) in Indiana (United States).

Pbud and Brand sold Chem an ounce of very high quality herb for 500 dollars that they called “DogBud”, an herb that they bought on the border of Colorado and Oregon in the year 88-89 and which was a cross between these three varieties: Thai weed, Hashplant and Skunk.

Joe Brand and ChemDog exchanged telephone numbers and later, ChemDog called Joe asking him for two more ounces to take them to the East Coast. According to ChemDog one of these ounces yielded 13 cannabis seeds and no more ever came out—for Pbud or Joe Brand either.

According to the story, in 1991 ChemDog germinated 4 cannabis seeds, from which he got a male that he had to throw out. Chemdog was a young grower and he didn’t know the importance of the males. The other 3 seeds began to flower. These were the famous Chem91, ChemDawg Sister and Chemdawg B.

In 2001 (it is said that ChemDog lost the genetic line through police intervention) the other seeds were germinated from the cannabis seeds that had been exchanged at the Grateful Dead concert. From these, one was trashed and the other two became ChemDawg D.

In 2006, ChemDog and Joe Brand reunited again and germinated 4 of the last 5 seeds. Of these, one remained—today’s “ChemDawg Reunion Pheno”.

It is assumed that ChemDog still has 2 seeds…


ChemDog creates Sour Diesel (SourD)


Update to 1993, ChemDog creates a cross between Super Skunk with his Chem91 which they called “Cock Diesel”. This clone was pollinated with a Northern Lights called DNL. The result has various names: UnderDawg, DayWrecker or No1 Diesel, and from this genetic voyage (Chem91 x Super Skunk/NL x DNL (pheno Skunk) Sour diesel was born, whose first packets were sold as Sour Diesel IBL of Resevoir Seeds of RezDog (ChemDog).

The organoleptic combination of Sour Diesel is impressive: The sour/acidic quality of Chem is mixed with various nuances that come from the Skunk, the most pure being a gasoline smell. The genetic Sour Diesel develops resinous tails with a pungent smell at about 67 days of flowering.

These are plants whose size duplicate amply during during the period of flowering, though they are not a “gluttonous” variety, though in good hands they can end up producing more than a half kilo of trichome heavy flowers per square meter with a THC % that can reach between 18% to 25%.

The effect is very balanced between cerebral and potent, but without being anesthetic. Some people use it to increase creativity, euphoria and a mental energy that makes you fly high while still having your feet on the ground.

I want to give thanks to the collaboration of the great Hydron of cannabiscafe.net for these years of acquired and shared knowledge on the forums. Thanks, friend.
