Description
Crazy Train FAST Feminized brings together two compelling genetic pillars: the legendary Atlas Jack Herer and Cotton Candy Auto. The result is a sativa-leaning cultivar with very high THC content pushing 25% and above, and an aromatic profile that layers pine and earth against softer floral and fruity notes, with a spicy, woody finish that lingers. Effects lean toward the clear-headed and energetic end of the spectrum, consistent with its Jack Herer heritage.
Atlas Seed engineered this early-fast feminized line for growers who want sativa performance without committing to a drawn-out season. Flowering wraps in 9 to 11 weeks, a meaningful advantage for indoor cultivators running back-to-back cycles or outdoor growers working against a shortening autumn. Indoor yields land between 450 and 600 g/m2, and outdoor plants are genuinely generous, capable of 450 to 750 grams per plant given the right conditions. The feminized format keeps things efficient and predictable. Growers looking to maximize return from a manageable sativa should give Crazy Train FAST serious consideration.

about this product
Crazy Train FAST brings Jack Herer's cerebral energy and 25%+ THC to an accelerated timeline, everything you need to run a sativa-dominant grow without the wait.
Atlas Seed positioned this one squarely at the beginner-to-moderate level, so it won't punish a grower who's still finding their feet. The feminized early-fast format removes a lot of the guesswork around sexing plants and season timing, making the whole process more forgiving from the start.
Unlike a standard feminized photoperiod that might push 12–14 weeks of flower, Crazy Train FAST wraps up in 9 to 11 weeks from flip. That shorter flowering window is built into the genetics through the Cotton Candy Auto lineage, so you get the sativa character of Jack Herer without committing to a drawn-out season.
Indoor growers can expect in the region of 450–600 g/m², which sits firmly in the high-yield bracket for a sativa-dominant variety. Plants stay at a manageable medium height, so you won't be fighting a canopy that's outgrown your space before harvest arrives.
The aroma and flavour profile layers piney and earthy base notes against floral and fruity overtones, with a spicy, woody finish that rounds things out nicely. The high is clear-headed and energetic — very much in the Jack Herer tradition — making this a daytime-oriented cultivar rather than something to reach for when you want to wind down.
