So back in the day (late 1970s) ....
I think modern strains with the word "blue" in it have some thai ancestors... at least that's what I've heard. It's legal here in CA...
My reading various internet sources gives the parents of Blueberry as a mix of Highland Thai, Purple Thai and Afgan.
I remember the first tokes of Thai Stick, my friend bought this stick with a few buds tied to it which I thought was an outrageous price for a few grams of pot since pounds of Mexican Dirt Weed were $75 to $125 a pound at the time, soaring head stone, trippy, and so much fun.
The laced sticks were great also, quite dreamy but it seemed within a year the quality diminished rapidly and what was sold as Thai Stick was just generic bud on a stick and no longer close to the real thing.
I'm vaping through an ounce of Pink Kush this month, really high thc, dense rock hard buds, but knocks me into couch lock similar to the head space of the heavy narcotics prescribed during and after my cancer treatment and bowel surgery.
The point being I find something lacking in some high thc strains and am leaning towards the various cannaboids/terpenes levels being so uneven due to the focus on the production of thc.
Strains similar to Pink Kush do work well for pain but hey I like a little fun with my medicine.You know after a day time toke session I'd like to feel a reduction in pain levels but also that boost of energy and inspiration to get moving and enjoy the day. I've spent enough time in couch lock from meds over the last few years that I need something different for daytime tokes.
Finally the point is I have some seeds of Blueberry x Strawberry Cough that just emerged this morning. Regular seeds so I can save some male pollen and cross with itself and with the Desil, which I enjoy, smells and tastes like lemon from the terpene limelon with a pine flavour from the terpene Pinene. Maybe the terpenes help make the cannaboids more bio-available, whatever but the Desil works way better for me than the Pink Kush which tastes like Morrocan hash, though the Pink probably higher in thc.
Hopefully the BlueBerry Cough will be a daytime toke to keep in the grow and the Pink, got 1 clone, can be reserved for evening and high pain usage.
