When it comes to Blue Toof Special, I have to say I am a fanboy as well. It was one of the first couple of indica-based autoflower seeds I have grown, that helped me tremendously with my sleeping issues. I have since found a couple of others I like but BTS was the first and still on my Mt Rushmore of sleeping meds. Her aroma is unmistakable. She is pure mango and I have a difficult time letting her be when she is flower. Not as heavy an aroma after the cure, but certainly still mango. Her size means I can run several tall 1 gallon rose pots ( that's what my hydroponic store guy calls them), and still get 40-60 grams from each one. So while she isn't a huge yielder, she fits my needs perfectly. Lastly is her effect. There is no playing around with any head high with this girl (at least IMO), pure body buzz that knocks me out. Most importantly, keeps me knocked out as long as any other strain I currently use for sleep meds. When I need a goodnight sleep, BTS is always in the mix for what meds to use.
But for me, it isn't the perfect bud. I have found it keeps me very tired (similar to a hangover) the next morning. Well rested yes, but can't seem to wake up and shake the cobwebs away until almost noon (for me about 6 hous or so). No other varieties I use leave me this way the morning after, just BTS. So the search for the Holy Grail (for me anyways) continues. My current all around favorite right now is Mephisto Strawberry Nugget Purple pheno. I seems to me to be the best all around nighttime meds, with no major drawbacks. But I like to rotate my nighttime meds so I don't build up a tolerance to any one strain. BTS, SNPP, 24 Carat, and Stone Dragon are on my current playlist. I highly recommend each and everyone of them.
Sorry for the long-winded answer.
