I have found that most all Mexican and Colombian land races are stable, and basically are one pheno and bloom consistently. At least from my bag weed land race seeds that I have grown. Colombian gold was a wide spectrum name for several types of Colombian weed in the 70s and 80s as well. The 'real deal' Highland or Santa Marta Gold form southeast Colombia, which was almost yellow, and the red or brown that was actually lowland Colombian that was fermented when green and turned brown or gold in color and was sold as 'lombo gold. The there was the well cured lowland narco red and west coast speedy sativa green, and the Punta Roja and Punto Rojo, but they were rare, as was the Colombian Black. Colombian black was also called Wacky Weed. It was truely psychedelic. There is a cut of it going around up here now. Blooms late and finishes in December from what I have been told. The Colombian gold that I grew was gold. Early on the leaves turned a golden green color, and later it was dark gold all over.
DJ Short (who is actually tall) is a nebulous creature, and has lived in California, Canada, Oregon, and Europe. Last I heard he was divorced and living in Oregon. Most of his strains were developed for indoor growing as I recall, but if he was referring to growing outdoors in the PNW, it was likely near the 45th parallel, give or take a few degrees. I know a guy near here that said DJ grew Flo for him on a medical card. I do not know when that was though.
Jack Herer was also from Portland. His marijuana store closed recently as the owners are tearing it down to develop on Hawthorne Blvd. His son was running the store until it closed. Mel Franks (not his real name) was originally from NYC and Mass, but he moved to Oakland where he still lives I believe.
