About Sour OG Feminised

Will Sour OG finish outdoors in Britain? Yes, within the April to October season. The balanced genetics cope with what British weather does from one week to the next, from damp air on the west coast to the drier run of counties in the east. Flowering runs 8-9 weeks, which puts harvest in September or October for most of the country.

What yield is realistic? 500g per m2 indoors is achievable with competent LED lighting and attention to feeding. Outdoors, 500g per m2 is realistic in 50 litre pots or in prepared ground with full sun β€” and "full sun" is doing a lot of work in that sentence at these latitudes, so the position you pick in the garden matters more than the pot you buy. At 20% THC with a myrcene-forward profile, the return on the effort is sound.

Is it forgiving? Reasonably. Anyone comfortable with pH, a feed schedule and a light timer will get a good result. It will not hold your hand, but it will not punish one missed watering either.

Further questions we get asked about Sour OG

Which medium? For flavour, peat-free soil cut with about 30% perlite and amended slowly β€” fish, blood and bone, rock phosphate, seaweed meal, all of it available at any British garden centre. For weight, coco with fertigation at EC 1.4-1.8 through bloom. This hybrid performs in both; the choice is about what you want out of it.

How does it handle a British summer? Well enough, on hybrid vigour. Keep the root zone under 28Β°C with mulch or pale pots, and do not transplant into a heatwave. The more common British problem is the opposite one: a cold, wet July that never lets the plant dry out between waterings.

When do I switch to bloom feed? Inside the first week of visible pistils. The 63/37 balance shifts its demand quickly at the transition β€” phosphorus and potassium up, nitrogen down. Soil growers can top-dress with guano and sulphate of potash; coco and hydro should move to a low-nitrogen bloom formula straight away.

Indoors or outdoors? Both work, for different reasons. Indoors you own the flowering environment completely. Outdoors, across the April to October season, the plant gets a light intensity no domestic LED matches and can reach 500g per m2 β€” at the price of accepting whatever the autumn does. Flowering: 8-9 weeks. Indoor yield: 500g per m2. Outdoor yield: 500g per m2. Rated intermediate difficulty.

What Sour OG is actually like

Growers report focused, energetic, calm as the defining characteristics and our own notes agree. At 20% THC this hybrid sits where the balance is the selling point. Taken small it stays functional; taken larger it relaxes properly. The ${indica}/${sativa} split means the direction is set by how much you take rather than fixed by the genetics. The Myrcene/Limonene pairing leaves earth and faint sweetness on the palate, with fruit at the end.

Best suited to most occasions β€” the dose does the steering.

Terpene breakdown

Primary: Myrcene Β· Secondary: Limonene Β· Tertiary: Pinene. 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, limonene occupies the middle, and pinene sits behind both β€” which is the part that separates this strain from others sharing its primary terpene.

Who it suits

Sour OG 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 β€” veg longer for bigger plants, or flip early when space is short. The April to October season accommodates a bloom of 8-9 weeks comfortably for outdoor growers across the country.

Sour OG Feminised β€” Breeder Information

Royal King Genetics

Bred and stabilised in-house by Royal King Genetics β€” 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.

Three-Generation Backcross Programme β€” recurrent-parent fixing
Stabilisation Notes β€” What This Means for Your Grow

BX3 is the credible stabilisation point for a clone-only recent-era cultivar. We worked Sour OG through three backcross generations to recreate the elite cut in seed form. A sibling male pollinates the mother each cycle to drive trait fixation.

Breeding Goal

Pin the structural balance of the elite cut into the population.

Selection Focus

Chosen for terpene profile, vigour, structure and finish-time consistency.

Pollen / Mother Source

Royal King Genetics in-house mother stock β€” pollen taken from a sibling male drawn from the same selected pheno population.
