About Dutch Kush Auto

Read Dutch Kush backwards from the harvest: up to 400 g/m2 under lights, up to 350 g/plant outdoors, with resin filling out towards 21% THC. Most of the final weight lands between weeks five and eight, when the 70/30 genetics stack calyxes quickly and the trichome cover goes from scattered to solid. Outdoors you want that stage falling in late August and early September while the light is still long, so count back to it from the first frost your own area usually sees rather than from a date on a packet.

Getting the weight out of this plant

Three stretches of the 50-60 days of bloom decide whether you reach the top of this strain's range (up to 400 g/m2 indoors, up to 350 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. Expect 20-30%, which is manageable; stripping the lowest fans around day seven sends the energy up to the sites that will actually finish.

Weeks three to five. Myrcene 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 15-20% amber for the weight of effect this genetics is bought for. Outdoors that lands between late September and mid-October across most of Britain, and the weather forecast should get a vote.

Flowering: 50-60 days. Indoor yield: up to 400 g/m2. Outdoor yield: up to 350 g/plant. Rated intermediate difficulty.

What Dutch Kush is actually like

Growers report creative, uplifted, energetic, calm as the defining characteristics and our own notes agree. At 21% THC this indica sits where dose control starts to matter. A single bowl through a vaporiser at 185°C gives a manageable physical ease with the head still working, which is what most people want at the end of a day. Push the dose and it moves firmly towards sedation — the reason it tends to become a winter evening cultivar rather than an all-year one. The Myrcene/Humulene pairing leaves earth and faint sweetness on the palate, with fruit at the end.

Best suited to quiet evenings, a film, recovery after exercise, and the hour before sleep.

Terpene breakdown

Primary: Myrcene · Secondary: Humulene · Tertiary: Linalool. These three build an aroma that keeps moving through the cure. Fresh off the dry it leads with myrcene; after three or four weeks sealed in glass at 16-18°C the linalool underneath comes up and the whole thing gains a layer. Vaporising between 180°C and 195°C catches the widest span of them, since the lighter linalool molecules are the first thing heat destroys.

Who it suits

Dutch Kush 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. Autoflowering genetics take the light cycle out of the equation, which suits balcony growers, anyone working around British daylight hours, and anyone who wants the whole thing over quickly. The April to October season accommodates a bloom of 50-60 days comfortably for outdoor growers across the country.

Dutch Kush Auto — Breeder Information

Royal King Genetics

Bred and stabilised in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read the full breeding process and about page.

Generations
5+
Breeding Programme
Autoflower Stabilisation (F5) — ruderalis trait fixing
Stabilisation Notes — What This Means for Your Grow

Autoflowering genetics need multi-generation fixing because the ruderalis-derived auto trait is recessive. Dutch Kush sits at F5 — every plant in the pack autoflowers reliably and finishes inside a tight window.

Breeding Goal

Lock the autoflower trait in Dutch Kush through five generations of selection.

Selection Focus

Chosen for trichome coverage, stout structure and consistent flowering time across the pack.

Pollen / Mother Source

Royal King Genetics breeding facility — pollen from internally selected sibling males of the recurrent parent.
