First, I think someone should talk to Shanti about the house rules, as I feel the sharing of genetics among forum members should be encouraged, especially considering how many members reside in areas where weed is now legal.
@iisfinxii, I'm not accusing you of being a liar, and I appreciate your perspective on the cough. But Occam's razor tells me the simplest explanation is the one most likely to be true. The Fort Collins cough showed up in the 1990s, about 10 years after Nevil opened the seed bank and many, many thousand NL5Hz of seeds had been shipped to many growers in the US who grew them out and found some excellent plants. Same decade as piff showed up in NYC. The simple answer is the cough is from Dutch stock. Was Haze 17 even available in the US? I thought it was selected in Holland by Sam. Or is that Haze 19? I just think the Dutch Nl5Hz connection is much simpler to explain that breeders in Colorado sourcing the same NL genetics that Nevil used, and then crossing with a haze cut from Sam. ALas, nobody will ever know for sure.
Also, while I'd like to have a genuine F1 Nl5Hz cut, I wouldn't be interested in one that was crossed to an OG and then subsequently had the OG bred out of it. I'm not trying to disparage your weed, just stating why an honest-to-God F1 Nl5Hz cut would be preferable to a haze lover over one that has been outcrossed to an Indica and bred all over the map.
All that said, do you know if the original Colorado Cough can be found? I recall reading here at MNS that a member found the cough in a Colorado dispensary within the last 10 years.
