I love the FoCo Cough clone, but I ditched it years ago because I couldn't handle running her (12-14 week strain with massive stretch) in the setup I had. Unfortunately, there's a couple wank 'Colorado Cough' strains floating about, including the one that Rare Dankness used for their original Fort Collins Trainwreck release (they have since updated the strain description to read like they are now using the real cough, so maybe they are now) and most of what is sold in dispensaries. The real Fort Collins Cough is a 90-100 day flowering plant, so not too many people grow it, and even less grow it well. Its getting harder and harder to find a good cut of the cough, as a cutting goes it is around ~20 years old, and so depending on who has been holding the cut you get, there are also reports of fairly substantial loss of vigor.
