There's a famous NL#5xHaze phenotype called Cat Piss. It's a legendary strain because it's psychedelic as fuck but damn, it tastes like fucking cat piss.
One of my favorite buds was a Chronic plant from Serious Seeds that smelled like a baby ate a peach and shit it out, mixed with alcoholic red wine puke. That was the bomb.
I've already smoked the Holy Grail of all Cannabis, though. When I think about it I could cry. My buddy back then grew it, the strain is called C4 from Chimera seeds but it was a one of a kind phenotype. It purpled so much that parts of the bud were solid black and it had bright orange hairs. I can't describe the taste because it was something else, man. I've never smoked weed like that again and I've smoked massive amounts of weed. It made me see yellow patterns of energy and was just so psychedelic but clear, it was bliss.
Yea, I had a couple of S1 seeds of that plant but the cops raided the place and stole my babies. ACAB.
One day... I'll be with you again C4. I'll never stop searching.
