42 Fast Buds – Trainwreck Auto
Old-school Trainwreck power as a fast autoflower
Trainwreck Auto by 42 Fast Buds brings one of the most famous West Coast genetics into a modern autoflower version. The legendary Trainwreck line has been known for decades for its energetic effect, intense terpene profile, and strong hybrid performance.
For the autoflower variant, this classic genetics was combined with stable Ruderalis genetics to create a strain that retains the typical Trainwreck character while offering a fast life cycle.
With up to approximately 22% THC, Original Trainwreck Auto delivers a powerful hybrid experience. The effect usually begins with a stimulating head high and subsequently develops into a relaxed physical effect – a balance that many growers and consumers particularly appreciate.
The plants grow vigorously and reach about 70–120 cm in height. Under optimal conditions, indoor growers can achieve 350–550 g/m², while outdoor grows can yield 60–150 g per plant.
Visually, the strain develops dense, light-green buds with orange pistils and a thick layer of trichomes. When the flowers are broken open, an intense scent of lemon, pine, and spicy notes, typical of Trainwreck genetics, unfolds.
The complete life cycle is about 8–9 weeks from seed to harvest, making multiple grow runs per season possible.
