About Tutankhamon Feminized

Here is what Tutankhamon delivers at harvest: 500 g/m2 per square metre indoors, 0.5-1.5 kg/plant per plant outdoors in UK conditions, with resin production peaking at 23% THC. Those numbers tell a story when you work backwards through the 60 days (LED: 53 days) window. Unlike quick-finishing indicas, this 12/88 cultivar distributes its weight gain across the full flowering period. Patience is non-negotiable — growers who chop early because they are anxious about autumn weather sacrifice 20-25% of their potential yield. For UK outdoor grows, that means committing to a harvest window from late September through October, depending on your latitude. The terpinolene-dominant terpene profile reaches peak complexity only in the final fortnight.

Maximising Your Harvest

To reach the upper end of this strain's yield potential (500 g/m2 indoors, 0.5-1.5 kg/plant outdoors), focus your efforts on three critical windows during the 60 days (LED: 53 days) period.

Window 1: The first 10 days after flowering begins. Stretch management determines canopy uniformity, which directly impacts light distribution and final yield. Stretch can reach 50-60% of pre-flower height. Supercrop any branches that outpace the canopy within the first week to maintain an even light field.

Window 2: Weeks 3-5 of bloom. Terpinolene terpene biosynthesis ramps up during this period. Maintain a day/night temperature differential of at least 6-8°C to encourage terpene accumulation — UK autumn evenings (September-October) naturally provide this swing for outdoor growers. Indoor cultivators should target 25-26°C during lights-on and 18-20°C during lights-off. Supplement with potassium-heavy bloom nutrients at EC 1.6-1.8.

Window 3: Final 10-14 days before harvest. Cease all nutrient input and flush with pH-adjusted water. Monitor trichomes daily with a 60x jeweller's loupe — harvest at 5-10% amber to preserve the cerebral, uplifting character. UK outdoor growers: this window typically falls from late September through mid-October.

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

What to Expect When Using Tutankhamon

UK customers report happy, energetic, creative as the defining characteristics, and our experience aligns with that consensus. At 23% THC, this sativa sits in a potency bracket where most users find a productive sweet spot. Vaporised at 175-185°C, the initial effect is a noticeable uplift in mood and mental energy that pairs well with creative projects, long walks, or an afternoon with friends. The body remains light and mobile throughout, making this a genuine daytime option for those with THC tolerance. The Terpinolene/Limonene terpene combination imparts a flavour that lingers on the palate — complex and shifting, revealing new notes across the session.

Ideal settings: creative pursuits, social gatherings, outdoor adventures, and daytime leisure.

Terpene Breakdown

Primary: Terpinolene · Secondary: Limonene · Tertiary: Ocimene. This particular terpene trio appears frequently in award-winning cultivars and produces a nose that most UK growers find immediately appealing when jars are first opened after curing. The terpinolene dominance anchors the aroma, limonene provides mid-range character, and ocimene contributes a subtle background note that distinguishes this strain from others sharing the same primary terpene.

Suitability and Recommendations

Tutankhamon suits growers with fundamental skills already established. You should understand pH management, basic nutrient ratios, and light cycle requirements before committing to this cultivar — it will not hold your hand, but it will not punish minor mistakes harshly either. Photoperiod genetics give you complete control over plant size and harvest timing — extend the vegetative phase for larger plants or flip early for a quicker turnaround in compact spaces. The UK growing season (April through October) accommodates the 60 days (LED: 53 days) bloom period comfortably for outdoor cultivators across the country. Shipped discreetly across the UK with our germination guarantee.
