Seb's take
Jack Herer crossed with AK-47, a connoisseur-grade pairing that produces large, trichome-heavy buds and a euphoric, energetic high. Sweet lemon citrus on the nose; the Sativa-dominant genetics tolerate warmer temperatures and heavier feeding, rewarding growers who push her. Stress resistance comes as standard, which is more than can be said for most of us.
Where it comes from
Jack Herer crossed with AK-47, two of the more decorated names in the catalogue, under Sweet Seeds' hand. The pairing is deliberate: Jack Herer for the euphoric lift, AK-47 for structure and resin. Seventy-five per cent sativa, and she carries the connoisseur billing the breeders give her without much argument. A cross of famous parents that manages to be more than the sum of them.
Nose & flavour
Sweet lemon and citrus, clean and bright, the sort of nose that suits the sativa lean. Nothing muddy or heavy here; it reads fresh, with the zest doing most of the talking. Large, trichome-coated buds carry it well. A cheerful profile, and an uncomplicated one.
The high
Euphoric and energetic, happy throughout, a lift that keeps you upright and engaged rather than folded into the furniture. THC runs eighteen to twenty-four per cent, which is a wide enough band to warrant a measured hand at the upper end. A daytime companion with proper stamina.
Growing it
She flowers in around sixty-six days and yields a solid 500 to 600 g/m². The sativa-dominant genetics tolerate warmer rooms and heavier feeding than most, so she suits growers who like to push. Stress resistance comes as standard; she takes training and technique in her stride rather than sulking. Indoors or out, she performs, though the warmth tolerance makes her a natural fit for the tent. Reward her ambition and she returns it.
