About Sweet Berry Auto
Days 1-14, germination and early veg. Sweet Berry generally cracks within about two days on damp kitchen paper and is above the medium by day three. The first fortnight came in even, without either racing or stalling. Four solid nodes by day 14 and the spacing that suggests the frame it will build. Keep the humidity near 70% and damping off stops being a concern.
Weeks 3-6, veg. A top at node four and a few ties produced six even leaders and a flat canopy across a 70cm square by the time it was flipped.
Bloom, weeks 1-9. The 38/62 character came through clearly. Limonene was noticeable by week three and kept building; resin was obvious without a loupe from about week five. Indoor yield: up to 250 g/m2. Height: 80–120 cm. Tested at 19%. Rated easy.
The rest of the run
Weeks 4-6, mid-bloom. Loose clusters from week three closed up into defined colas. Development stayed even across the canopy, which is what the veg training was for: eight comparable colas instead of one dominant top and a set of stragglers.
Ripening, weeks 7-9. Plain water for the last ten days. Limonene was strong enough by then that carbon filtration was not optional in a terraced house. Heads went clear to milky over the final fortnight, amber showing on sugar leaves first, and around 15% amber on the calyxes is a defensible place to stop.
Drying and curing. Hung whole in the dark at 17°C and 58% humidity for twelve days, both held by a dehumidifier because an October room here will hold neither. Stems snapped instead of bending, which is the only test worth trusting. Four weeks in glass after that. The up to 250 g/m2 figure held up. Caryophyllene was far more present after the cure than at harvest — the cure makes flavour, it does not merely preserve it.
Flowering: 50-60 days. Indoor yield: up to 250 g/m2. Outdoor yield: up to 400 g/plant. Plant height: 80–120 cm. Rated easy difficulty. Regular seeds, autoflowering.
Flavour, aroma and effect
Sweet Berry arrives in order. The first draw at 19% THC gives citrus with a bitter edge that lifts off the palate. The creative, calm character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Caryophyllene underneath contributes warmth that keeps it anchored.
Terpene breakdown
Primary: Limonene · Secondary: Caryophyllene · Tertiary: Linalool. This is a combination that turns up repeatedly in cultivars people rate, and it is usually what gets commented on when a jar is opened for the first time after a proper cure. Limonene anchors it, caryophyllene holds the middle, and linalool sits behind both — the last of those being what separates this from other strains leading on the same terpene.
Who it suits
Who does well with Sweet Berry? Back-garden and balcony growers in Dublin, Cork and Galway. Anyone who wants a crop dry and put away before the autumn closes in. Indoor growers short of headroom. The autoflowering genetics run to their own clock, so there is no schedule to manage and no anxiety about light leaks. Rated easy, which means a moderate learning curve that rewards attention without needing specialist kit.

Sweet Berry is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the flavour saturation the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Lock the autoflower trait in Sweet Berry through five generations of selection.
Chosen for terpene profile, vigour, structure and finish-time consistency.
