That is the smell of Haze.
It is 100% pure sativa originally created by the Haze Brothers using Acapulco Gold / Columbian Santa Marta Gold / South Indian Kerala / Highland Thai (original Thai sticks). Sam the Skunkman made it all famous. Google him...Seedsman carries the Original Haze and I think Sam is still the breeder. Many of todays high quality hybrids contain some of this "secret ingredient" e.g. Jack Herer. Haze can only be grown outdoors in equitorial climates due to the high lumen requirements or indoors in high ceiling rooms with HID lighting. It is not a commercially viable crop and is considered purely connoisseur. Tough to grow and extremely long to flower (14-18 weeks). Low yields, long flowering, difficulty in growing make this quite a rare and expensive toke.
This variety should contain a warning:
This can and probably will cause paranoia. Extended use can, and will probably, cause psychotic behaviour. This will subside when use is discontinued (so tell your Psych to FO with the anti-psychotic meds). Haze is NOT for newbies smokers or growers...
This strain has medical interest for Epilepsy or MS patients. This pot, if grown correctly, is like acid and speed. VERY STELLAR. Considered by many, to be the best pot in the world. People will believe that it is laced with something (AKA speed weed). There is no ceiling when toking. Each toke will get you much higher. The reason for the lack of ceiling is the low CBD ratio compared to the THC. This is an EXTREME sativa and most growers are doing Indica. This stuff can make you puke and pass out so be careful. Hallucinations, extreme laughter, improved creativity, great for walks in the park. DO NOT SMOKE AT NIGHT...you will NOT sleep.
