Quantum Kush Auto

Germination and early veg, days 1-14. Quantum Kush 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 25/75 balance in Quantum Kush 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: up to 450 g/m2. THC testing at 23%. Rated intermediate.

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 up to 450 g/m2 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: 50-60 days. Indoor yield: up to 450 g/m2. Outdoor yield: Up to 550. Rated intermediate difficulty. Regular seeds with autoflowering genetics.

Quantum Kush arrives in stages. The first draw at 23% THC brings clean resin, like woodland after rain. The euphoric, happy, uplifted 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.

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 does well with Quantum Kush? Balcony growers in flats from Brighton to Glasgow. Anyone wanting one quick outdoor crop rather than a long project. Indoor growers short of headroom. The autoflowering genetics run on their own clock, so there is no light schedule to manage, no anxiety about light leaks, and harvest comes 10-12 weeks from germination whatever the season is doing. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.
