I have "heard" endless sky is extremely potent. I find the whole THC percentage thing to be more of maybe a marketing ploy than anything imo. When someone says "this pot is 22% THC" what does that mean to us as consumers? 22% per pound, per ounce, gram? What? Potency is determined by many other Cannabinoids besides THC. I often wonder about these "stated" percentages and how they came to be.
I was wondering what some of the answers were gonna be, but I would have to go with Endless Sky...in over 20 yrs I have seen none like it......although I haven't tried Super Silver Haze yet....hmmmm..... but I can't imagine anything stronger. Anything stronger would mean a trip to the Hospital...lol
To be honest there is no most potent Cannabis, there is only the most potent for you. Cannabis has many componates that contibute to the subjective effects, THC is the most important, but if you smoke pure 100% THC you will be shocked to find it is not stronger then 50-70% THC resin. All of the different reported subjective effects of Cannabis are a result of the additional componates besides THC. But each person responds differently and desires different componates with the THC. There is no best just personal preference. Example: Do you like couchlock Indica's or soaring Sativa's? If you say Indica then no Sativa will be the best, and if you love Sativa's then a super potent Indica will not be your preference, even if it has more THC.
Cannabis subjective effects are not simple, and any attempt to boil it all down to THC is doomed to failure.
I suggest you find a Cannabis that has the taste and type of high you like as well as being strongest.
The question is: what is the most potent cannabis strain available?......not the highest thc content or if it's an Indica or Sativa....It's just like asking, " what is the strongest coffee brand? " There really is no big science to it...or shall I say, There is no need to be scientific about it......and I'll say again, " Endless Sky is ultra potent period! "...I like Indica's and Sativas...but that Iranian Indica is something else...the shit is too strong!!.....just my 2 cents, that's all(smile).
