Purple Trainwreck is a hard-hitting flavour-bomb, born from distant but surprisingly complementary origins: Mendo Purps x Trainwreck. This feminised, Indica-dominant cannabis strain holds the potential for speedy flowering, a dazzling colour display and potent highs.

Purple Trainwreck can grow to a heighty 3m outdoors and puts on an exquisite show of purple hues, when night-time temperatures drop optimally during flowering.

These feminised seeds deliver gorgeous yields of smelly, trichome-packed flowers.

Purple Trainwreck delivers hints of citrus and spices to the sinuses, blended beautifully with the unique, intense taste combo of lemon, lavender and pine.

The experience is extraordinarily potent and not for the faint-hearted or inexperienced. Very psychedielic and cerebrally uplifting, initially, followed by a "second wind" of intense physical relaxation that lasts a long time.

Purple Trainwreck is a colourful beauty that loves additional nutrients and is resistant to humidity and disease. Due to her likelihood of stretching greatly, it’s best to limit veg growth indoors. When grown outdoors, she thrives in warmer, Mediterranean-like conditions or the shelter of a greenhouse. And don’t forget that dazzling colour display, with enough of a temperature drop at night, when she’s flowering.
