Last QC test date: 2026-09-03

Outdoor yield: 529-750 g/plant (avg across 8 verified grower reports)

About Big Cheese Auto

Read Big Cheese backwards from the harvest: 400 g/m2 under lights, 40-60 g/plant outdoors, with resin filling out towards 21% THC. Most of the final weight lands between weeks five and eight, when the 84/16 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 10 weeks (approx. 77 days) of bloom decide whether you reach the top of this strain's range (400 g/m2 indoors, 40-60 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: 10 weeks (approx. 77 days). Indoor yield: 400 g/m2. Outdoor yield: 40-60 g/plant. Rated intermediate difficulty.

What Big Cheese is actually like

Growers report happy, euphoric, energetic 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. 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. Myrcene anchors the aroma, humulene occupies the middle, and linalool sits behind both — which is the part that separates this strain from others sharing its primary terpene.

Who it suits

Big Cheese 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 10 weeks (approx. 77 days) comfortably for outdoor growers across the country.

Stabilisation Notes — What This Means for Your Grow

Big Cheese is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the purple expression the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.

Breeding Goal

Reach auto trigger and finish-window uniformity for the Big Cheese pack.

Selection Focus

Chosen for purple/dark expression where it shows, dense bud structure and a true indica relaxation profile.

Pollen / Mother Source

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