Sirius Black strain by Oregon Breeders Group is Indica-dominant hybrid with an 80/20 genetic mix. The lineage of this strain is as mysterious as a wizard named Sirius Black in Joanne Rowling's books about Harry Potter. The thing is, the breeder decided to keep the lineage of this strain covered. Oregon Breeders Group informed that they bred this cannabis in Portland in the 1980s as part of the Sirius Black project to create the perfect dark purple bud.

Smoking this weed for a while now and I get long-lasting result everytime. My doctor recommended it o me as I was battling with chronic pain in my body. After incorporating the edibles in my diet, I started getting results as soon as possible. The effect was so instant and euphoric. So far, I haven’t been feeling any pain and I feel so energetic from within.

How is your Sirius Black coming along. My colas are still really skinny, but pistils are mostly brown and am getting amber trichomes. 3 seeds and the plants are totally different from each other.
