About Coffee Feminised

Read Coffee backwards from the harvest, with resin filling out towards 24% THC. This 12/88 cultivar spreads its weight gain across the whole of bloom instead of front-loading it the way a quick indica does. Cutting early out of nerves about the weather is the most expensive mistake made with plants of this shape. In Britain that means holding through late September and into October depending on your latitude, because the limonene-led profile only fills out in the closing fortnight.

Getting the weight out of this plant

Three stretches of bloom decide whether you reach the top of this strain's range. 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. It can add half again its height. Supercrop anything that breaks the line of the canopy inside the first week or you will spend the rest of bloom lighting one branch properly and five badly.

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 5-10% amber to keep the clear, lifted character intact. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Rated intermediate difficulty.

What Coffee is actually like

Growers report relaxed, creative, focused as the defining characteristics and our own notes agree. At 24% THC this sativa sits where most people find a workable window. Vaporised at 175-185°C the first effect is lift and mental energy, suited to work that benefits from it, a long walk, or an afternoon with company. The body stays light throughout, which makes it a genuine daytime option for anyone with a tolerance. The Limonene/Terpinolene pairing leaves a clean citrus finish that clears quickly.

Best suited to creative work, company, getting outdoors, and daytime use generally.

Terpene breakdown

Primary: Limonene · Secondary: Terpinolene · Tertiary: Pinene. How this profile survives the journey from flower to vapour depends on temperature. Low vaporisation, 180-188°C, keeps the terpinolene and pinene 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

Coffee suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Photoperiod genetics leave plant size and harvest date under your control — veg longer for bigger plants, or flip early when space is short. The April to October season accommodates the bloom period comfortably for outdoor growers across the country.
