About Tutankhamon Feminised

Read Tutankhamon backwards from the harvest: 500 g/m2 under lights, 0.5-1.5 kg/plant outdoors, with resin filling out towards 23% 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 terpinolene-led profile only fills out in the closing fortnight.

Getting the weight out of this plant

Three stretches of the 60 days (LED: 53 days) of bloom decide whether you reach the top of this strain's range (500 g/m2 indoors, 0.5-1.5 kg/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. 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. Terpinolene 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.

Flowering: 60 days (LED: 53 days). Indoor yield: 500 g/m2. Outdoor yield: 0.5-1.5 kg/plant. Rated intermediate difficulty.

What Tutankhamon is actually like

Growers report happy, energetic, creative as the defining characteristics and our own notes agree. At 23% 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 Terpinolene/Limonene pairing leaves a finish that keeps changing across a session.

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

Terpene breakdown

Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. This combination turns up often in cultivars that win things, and it is usually the one growers comment on when a jar is opened for the first time after curing. Terpinolene anchors the aroma, limonene occupies the middle, and ocimene sits behind both — which is the part that separates this strain from others sharing its primary terpene.

Who it suits

Tutankhamon 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 a bloom of 60 days (LED: 53 days) comfortably for outdoor growers across the country.
