We've done critical haze outdoor for the last two years, and love it--it's become a staple. Like the mr nice page says, there's a lot of variation, thanks to all the genetics that make it up. A few of the ones we've grown were really not so great for our climate. But most have been lovely, GIGANTIC plants that were our best producers, averaging over 5 elbows per plant.
The nugs have an herby, lemony sort of smell and flavor, and when properly cured the smoke is real smooth and tasty. Not the strongest stuff I ever smoked, but it tends to be sativa dominant, so you can't expect to be floored, and it's not bad either. Pretty uppy and very pleasant. Good luck!
