the "trinity" my friend sold me a z of was the funk, that was like 15 years ago, the day after a phish show though so i can barely recall anything except it glowing like gold when my buddy pulled it out of his stash on a morning when i had no clue if id see any decent bud anytime soon (anyone else recall those horrible times?) I remember it was somewhat fluffy, i believe it was skunky/sort of diesel, but i have no idea, he said it was from "white Rastas" up in norcal. hah... that probably didnt help anyone at all, but it was really dank.
ive grown all three: 91, d, and 4.... imo 91 most resembled the sour d (obvious) but not as robust so i eventually dropped it based on the finickyness, the chem d was also notoriously finicky and didnt have the stretch of the 91, not to mention back then everyone thought the variegation was tobacco mosaic virus. IMO they had similar skunk funk diesel, though batch to batch was the main influence. I can totally see the chem d influence on the GMO cut, almost as if it turned down the skunk and turned up the garlic. when nailed, the chem d was insane, my homies in western mass always brought the dank chem d nugs w them to "gd events", i usually brought the sour from the next state over. i got a cut of the 4 later on (maybe 9 years ago?) and the thing about the 4 is it doesnt have the same chem diesel funk as the d or 91. more of a lemon cleaner with a hint of chem... at the time i had plenty of flavors like that (jack the ripper, super lemon haze, silver haze, silver kush (unknown origin)) so she didnt stick around, but i will say she was by far the easiest to grow for me... this could be to better grow skills, or condition of the cut, but she was tall and leggy with big foxy nugs. Def the best yielder for me, but not really what "gas" heads are lookin for. 4 was really good, and i would have kept her based on yield alone. chem sister is around as well and has been worked into many local lines but i never had the pleasure myself. Based on the original pbud/chemdog story... isnt it possible that all the chemdog seeds were not from the same father plant, or even mother plant? Unless all of the seeds were contained in the same nug, how can anyone say the bag of "dog weed" even contained all the same exact mother plant? it could have been a worked line with similar phenos and multiple pollen donors. They could also be from one female plant that self pollinated. Although i believe i heard chem himself say there was a male, but that doesn't eliminate the possibility of both female and male (or multiple of both) pollen donors. Pure conjecture here. Have a Grateful One people!
