Sweet Trainwreck Auto feminized seeds


A Californian, Sativa-dominant Hybrid

Sweet Trainwreck Auto is a 4th generation autoflower that came about as a cross between a development autoflower and the famous North American strain Trainwreck – a potent, Sativa-dominant staple in dispensaries across the West Coast.

This tall-stemmed, Sativa-dominant hybrid can be grown both indoors and outdoors however, due to her genetic lineage, prefers slightly warmer climates. Those growing outdoors in the Northern Hemisphere can achieve this by using a greenhouse to boost temperatures. A little bit of training goes a long way with this strain and grow methods such as SCRoG can really improve the quality and quantity of your harvest. Indoor yields for this strain are between 350 – 550 g/m2, while outdoor growers can achieve 40 – 120 g per plant with a total grow time of 8 weeks. Here is some further information to help you grow this strain:

  • Medium height – reaches a final height between 0.6 – 1.2 m depending on the phenotype.
  • Max EC of water – 1.0 in veg, up to 1.4 in flower.

  • Recommended lighting: 450 W LED.
  • Recommended nutrients: CANNA COCO range.
