1991 Chemdog is a legendary strain that has its origins in the lot of a Grateful Dead concert.
Here, “Mass G” purchased cannabis dubbed “dog bud” by the seller. From the dog bud came several seeds, one of which went on to become Chemdog! This plant is a super narcotic, short, gassy plant, which lent the “diesel” to the “sour diesel” we all know and love. Then Chemdog 91 mother was crossed to a ruderalis type for its autoflowering qualities, then inbred to the point of an autoflowering Chemdog type!
WARNING: as with all autoflowers, these plants will flower when root-bound. It is advised to plant the seed in its final pot after germination, or be very diligent in repotting to larger containers.
