Feminized Marijuana Seeds | Sativa | THC >20%

Just a few years ago, the THC content of over 20% was an exception, reaching only a handful of varieties. Legendary are the varieties Super Silver Haze by Greehouse Seeds, as well as Amnesia by Super Strains. Also Jack Herer by Sensi Seeds belonged to these precursors with extremely high THC levels. Not to forget: these cannabis seeds have been available for well over 20 years. Since then, however, cannabis breeding has increased in the truest sense of the word. At the latest with the complete legalization of marijuana in Canada and large parts of the USA, new standards in terms of potency were set. Cannabis varieties with a THC content of over 20% today belong to the standard range. Varieties such as Bruce Banner or A5 Killer Haze, if grown in good conditions, will yield 25% THC or more. So these varieties are more for the hard-boiled. In any case, high THC levels should be well tolerated.
