About Zashimi Feminised

Read Zashimi backwards from the harvest: 200-300 g/m2 under lights, 300 g/plant outdoors, with resin filling out towards 23% THC. Weight goes on evenly across the 8-9 weeks of bloom, with a clear surge in the last two weeks that rewards leaving the plant alone. The 49/51 split gives you calyx density and an even spread of resin rather than one at the cost of the other. Outdoors, late September to mid-October is the window that misses the wettest of the finish across most of the country while still letting the limonene arrive.

Getting the weight out of this plant

Three stretches of the 8-9 weeks of bloom decide whether you reach the top of this strain's range (200-300 g/m2 indoors, 300 g/plant outdoors). The rest is maintenance.

The first ten days of flower. What the plant does during the stretch sets canopy height, and canopy height sets how evenly the light lands. Somewhere around a third is typical. One pass of low-stress training over the tallest shoots keeps the top flat.

Weeks three to five. Limonene production climbs through here, and it responds to a day-night temperature gap of 6-8°C. British autumn nights hand that to outdoor growers for free from September; indoors you have to build it, at roughly 25-26°C lights-on and 18-20°C lights-off. Bloom feed goes potassium-heavy around EC 1.6-1.8.

The last ten to fourteen days. Stop feeding and run pH-corrected water. Check trichomes daily under a 60x loupe — cut at 10-15% amber for the middle of the range. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Flowering: 8-9 weeks. Indoor yield: 200-300 g/m2. Outdoor yield: 300 g/plant. Plant height: 152-244 cm. Rated intermediate difficulty.

Flavour, aroma and effect

Zashimi arrives in stages. The first draw at 23% THC brings a bright citrus edge that lifts off the palate immediately. The relaxed, happy, euphoric character follows within minutes, as a head and body effect at once. The mind stays clear while the muscles let go by degrees, which is what makes it adaptable — a small dose carries an afternoon, a larger one turns into an evening. The caryophyllene underneath adds a warmth that keeps the whole thing anchored.

Terpene breakdown

Primary: Limonene · Secondary: Caryophyllene · Tertiary: Linalool. How this profile survives the journey from flower to vapour depends on temperature. Low vaporisation, 180-188°C, keeps the caryophyllene and linalool audible over the limonene 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 Zashimi? 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.
