About Purple Wreck Feminised

Germination and early veg, days 1-14. Purple Wreck seeds generally crack inside 48 hours on damp kitchen roll and break the surface around day three. Early growth came in fast and upright, the first narrow leaves reaching for the light from the start. Five nodes by the end of week two with obvious space between them, which tells you what the stretch is going to do later. Damping off is rare around 70% relative humidity, which is also roughly what an unheated British room sits at in spring.

Veg, weeks 3-6. Vertical growth needed managing. Even with low-stress training from week three it wanted to climb, so the main stem went over at a right angle in week four; the secondaries caught up and the canopy was flat by week six.

Bloom, weeks 1-9. This is where the 14/86 balance in Purple Wreck showed itself. The pinene came up in week three and kept building; trichome cover was obvious to the naked eye from week five. Indoor yield: 400-490 g/m² indoors. Height: 78-89 cm. THC testing at 22%. Rated intermediate.

The rest of the diary

Mid-bloom, weeks 4-6. The change came quickly. Sites that were loose and wispy at week three closed into defined colas. The buds kept extending lengthwise, stacking fresh calyxes along the stems. The secondaries outperformed expectations: the open structure let light reach sites that a bushier plant would have shaded out completely.

Ripening, weeks 7-9. Feeding dropped to plain water for the last ten days. The pinene got strong enough that carbon filtration stopped being optional in a terraced house. Trichomes ran clear to milky across the final fortnight, amber showing on sugar leaves first. Around 15% amber on the calyxes is a common place to stop.

Drying and curing. Whole plant hung in the dark at 17°C and 58% humidity for twelve days — both numbers held by a dehumidifier, because an October room in this country will not hold either on its own. Stems snapped rather than bent, which is the test worth trusting. Four weeks in glass followed, burped twice daily for the first fortnight and once daily after. Final weight matched the 400-490 g/m² indoors figure. The limonene was far more present after the cure than at harvest, which is the argument for curing properly: the process makes flavour rather than merely keeping it.

Flowering: 9 weeks. Indoor yield: 400-490 g/m² indoors. Outdoor yield: Up to 450 gr. Plant height: 78-89 cm. Rated intermediate difficulty. Feminised seeds.

Flavour, aroma and effect

Purple Wreck arrives in stages. The first draw at 22% THC brings clean resin, like woodland after rain. The relaxed, euphoric, creative, energetic character follows within minutes, arriving as sharpened attention. Colour reads brighter, music reads busier, and conversation wanders further than it would otherwise. It holds for two to three hours on a plateau rather than a spike. The limonene underneath adds a lift that stops it turning heavy.

Terpene breakdown

Primary: Pinene · Secondary: Limonene · Tertiary: Caryophyllene. How this profile survives the journey from flower to vapour depends on temperature. Low vaporisation, 180-188°C, keeps the limonene and caryophyllene audible over the pinene base. Run it hotter, or burn it, and the three collapse into one note — pleasant enough, but none of the complexity that made it worth choosing.

Who it suits

Who does well with Purple Wreck? Indoor growers who want the timeline under their own control. Outdoor growers who want to choose when flowering starts. Anyone with the room and the patience to veg it properly before flipping. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.
