Trainwreck is a heavy-yielding cannabis strain that packs a punch. This sativa-leaning, feminised hybrid is a thoroughbred from Humboldt County, California. Trainwreck’s scent is a mix of spicy Kush, sour fruit and cedar wood. Her delicious flavour combines, exotic wood, tangy citrus, oil and spices. The effect is strongly narcotic, blending into a marvellous and lengthy physical relaxation.

Trainwreck was born from an elite Sativa-derived clone and, although her exact parent strains are unidentified, her Californian birthplace is certified as Arcata, Humboldt Bay. The result is a beautiful Sativa hybrid that loves to stretch and can reach 3m outdoors.

Extraordinary amounts of huge cannabis flowers, covered in a shiny, resinous trichome layer.

Prepare for an experience so powerful, you might think you’ve been hit by a train. The effect is strongly narcotic, blending into a marvellous and lengthy physical relaxation.

Trainwreck grows vigorously and it’s recommended to limit vegetative growth to roughly 3 weeks indoors. Outdoors, she prefers dry, sunny, Mediterranean conditions. Though she’d thrive in a greenhouse too.
