Seb's take
Sour Diesel and Super Silver Haze, unmixed with anything gentler — a pure sativa that stretches tall and does not travel discreetly, announcing itself before the buds even finish. Fuel and skunk lead the nose with a citrus trace beneath, and the high stays mentally alert, a proven wake-and-bake choice with cup wins across three different decades.
Where it comes from
Growers Choice crossed Sour Diesel with Super Silver Haze and left the result unmixed with anything gentler, arriving at a 100 per cent sativa that leans hard into its cerebral heritage. Both parents are heady in their own right, and together they make a plant that stretches tall and does not travel discreetly. The reputation is backed by results too: the strain claimed wins at the IC420 Growers Cup in 2009 and 2010, followed years later by a Magnolia State Cannabis Cup victory in 2024, cup honours across three different decades.
Nose & flavour
A loud, skunky aroma that announces itself early in flowering and does not travel discreetly thereafter. Fuel and skunk lead the nose, layered with herbs and a faint citrus edge beneath, a profile that feels old-school but stays aggressive. The diesel is the unmistakable signature, the citrus a thin bright line under all that fuel. A room-filling scent that makes its lineage plain long before the buds finish.
The high
The effect stays mental and alert, the pure sativa heritage keeping the head engaged throughout. It runs happy, focused and euphoric, a bright, lucid high that lifts the mood and sharpens the attention rather than settling the body. A proven wake-and-bake choice, well suited to long, focused afternoons, the kind of effect that sets you going and keeps you there. Cerebral company that stays upright.
Growing it
The record gives no height, but the temperament is plain: the plants stretch tall and develop resin-heavy buds, so give her the headroom a pure sativa of this stock will take. Flowering runs 65 to 75 days, patience the price of the cerebral heritage, and the yield is a modest 305 g/m². THC sits at a serious 25 per cent, with a touch of CBD at 1 per cent. A tall, loud, resinous sativa whose cup record across three decades is reason enough to give her the room and the wait she asks for.
