Years ago i read that Subcool had said that Black Cherry Soda was in fact Blackberry Kush.
But at the time, Kushes were flooding the market and Sub didn’t like the “Kush” association. So he changed the name to Black Cherry Soda when he used it in Ace of Spades and Plushberry.
I suspect there is a high level of THC-V in Blackberry Kush.
Annunaki Genetics is the best breeder of BCS hybrids i grew years ago. But most of that work is sold out now.
Except F2s of Annunaki Genetic’s Huckleberry Soda (Black Cherry Soda x Huckleberry Hound). This strain had a very strong body effect for me but didn’t make me sleepy.
These are available again from Seedsforme in Washington state, and i highly recommend.

While in the Annunaki section, check out the Annunaki Gift Seeds page. They have a Black Cherry Soda x Sour Cyclone (CBD) cross available.

Also, Purple Caper Seeds sells a Blackberry Fire that uses a Blackberry Kush mom. I have smoked the BF and it was superb. Clones were available at Dark Heart Nursery.
Good luck in your quest, i will update if i find new sources for BCS genetics.
