Well, pimpin', I have to believe the original breeders- monks in Mexico? The genetics got passed to a fellow named Danbo who worked them for awhile... Reef claims he got the seeds (or parental cuts) from Danbo (a regional legend of sorts)...
So we now have two independent breeders confirming the genetics -Adam at THSeeds- thank you Snowcap- I remember ;)! and Reef's team...
I mean really, when someone passes you a bag of seeds (or weed) and says it's Oaxacan or Acapulcan or Guerreran- you take a look at them, make your own decision whether or not he is full of shite, grow out the seeds and compare to what you know and your experience, then make a call as to what strain you got (or weed you smoked)...
By now, 2009, the various Mex strains may have some genetic mingling involved... I mean could you tell the difference between Acapulco Gold and Guerreran Green??? Between the different phenos, length of flowertime, nutes, harvest windows, different cure methods??? It's a bitch! Takes great memory and even better notes and pics...
Zacatecas Purple is most likely extinct- sprayed by paraquat, left out of the genetic pool, not collected because it's not very marketable like Acapulco Gold or Kush (for christ's sake)... Sure, you could get on a plane and go on a seed safari to Central Mexico, suck up the costs, resist the diseases, experience the full flavor and smell of poverty off the beaten path and collect some 'authentic?' Zacatecas beans and start your selections with around 80 to 100 plants that flower in 14-20 weeks on the 20th N...
Or, you can buy a couple packs from Reef. Not likely to be available elsewhere either... If you want something very rare and different- non Dutch- trippy wiggy weed with a sativa high look to the BigSurHolyWeed...
Reeferman and his team have always been known for excellent sativa genetics. One of his strengths as a breeder is his ability to find these rarified genetics and bring the seeds to us... BigSurHolyWeed is a prime example of this activity...
