About OG Kush Auto
The way to plan OG Kush is backwards from the day you intend to cut, with 400-450 g/m2 per square metre indoors and 50-170 g/plant per plant outdoors as the figures you are working toward, at 19-25% THC. Count 10-12 weeks seed to harvest back from that date and you have your flip date. Weight comes on evenly across 10-12 weeks seed to harvest, with a late surge that punishes impatience. The 55/45 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.
Where the Weight Actually Comes From
Yield on OG Kush — the 400-450 g/m2 indoors and 50-170 g/plant outdoors quoted above — is decided in three short stretches of the 10-12 weeks seed to harvest bloom rather than evenly across it.
The first ten days after the flip. Whatever stretch happens here sets your canopy, and an uneven canopy wastes light for the remainder of the grow. Stretch of 30-40% is normal. One round of low-stress training on the tallest shoots levels it out.
Weeks three to five. This is when myrcene production climbs, and it answers to the gap between day and night temperature rather than to either number on its own. Keep at least 6-8°C between them. Outdoor growers in the interior provinces get that swing free in March and April; indoors, aim for 25-26°C lights-on against 18-20°C lights-off, with potassium-led bloom feed at EC 1.6-1.8.
The last ten to fourteen days. Stop feeding, flush with pH-corrected water, and read trichomes daily under a 60x loupe. Cut at 10-15% amber to keep both sides of the hybrid in play. Outdoors that usually lands between late March and mid-April.
Difficulty: easy. In flower for 10-12 weeks seed to harvest. Stands 60-120cm. Indoors it returns 400-450 g/m2. Outdoors, 50-170 g/plant a plant.
What OG Kush Is Like to Use
The effects most commonly reported for this cultivar are euphoric, relaxed, happy. At 19-25% THC it sits in a bracket where flexibility is the point. Lower doses read clear and functional in the morning, higher doses read relaxed in the evening. Because the 55/45 split is even, direction is set by how much you take rather than fixed by the genetics. The Myrcene/Limonene pairing leaves an earthy sweetness with a fruit finish on the palate.
Where it fits: most occasions, with the dose adjusted to whatever the situation asks for.
The Aromatic Three
Leading with Myrcene, then Limonene, and Pinene underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of OG Kush tends to get a reaction the first time it is opened after curing. Myrcene sets the anchor, limonene fills the middle, and pinene sits in the background doing the work that separates this from every other strain built on the same primary terpene.
Suitability and Recommendations
OG Kush is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Because it autoflowers there is no light cycle to manage at all, which is what makes it work on a balcony, in an out-of-the-way outdoor spot, or anywhere a timer would be one more thing to go wrong. A September-to-May outdoor season comfortably covers a 10-12 weeks seed to harvest bloom in the frost-free provinces.

OG Kush Auto — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics , the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
OG Kush is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the bud density the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Stabilise the recessive ruderalis trait in OG Kush for uniform auto-trigger.
Chosen for terpene profile, vigour, structure and finish-time consistency.
