About Cali Kush Feminised

Will Cali Kush finish outdoors in Britain? Yes, within the April to October season. The habit is compact enough to stay below a fence line, and the dense flower structure puts real weight on a small frame β€” which is also the reason airflow matters more here than it would in a drier place. Flowering runs 50-60 days, which puts harvest in September or October for most of the country.

What yield is realistic? up to 500 g/m2 indoors is achievable with competent LED lighting and attention to feeding. Outdoors, up to 400 g/plant 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 24% THC with a caryophyllene-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 Cali Kush

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 indica performs in both; the choice is about what you want out of it.

How does it handle a British summer? The dense foliage shades itself, which helps. Above 30Β°C growth stalls but the plant does not fold. Mulch the root zone and water before seven in the morning and heat stress stops being a factor in nearly every part of the country. 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 90/10 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 up to 400 g/plant β€” at the price of accepting whatever the autumn does. Flowering: 50-60 days. Indoor yield: up to 500 g/m2. Outdoor yield: up to 400 g/plant. Rated intermediate difficulty.

Flavour, aroma and effect

Cali Kush arrives in stages. The first draw at 24% THC brings dry pepper that registers at the back of the throat. The happy, relaxed, uplifted character follows within minutes, starting as weight behind the eyes and working down through the shoulders and chest. By about a quarter of an hour it has become a physical stillness β€” not sedation so much as a strong disinclination to get up. Two to three hours at a moderate dose. The myrcene underneath adds body and depth beneath the rest.

Terpene breakdown

Primary: Caryophyllene Β· Secondary: Myrcene Β· Tertiary: Bisabolol. 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. Caryophyllene anchors the aroma, myrcene occupies the middle, and bisabolol sits behind both β€” which is the part that separates this strain from others sharing its primary terpene.

Who it suits

Who does well with Cali Kush? Indoor growers who want the timeline under their own control. Outdoor growers who want to choose when flowering starts. Anyone with the room and the patience to veg it properly before flipping. Difficulty is rated intermediate, which means a moderate learning curve that rewards attention without demanding a laboratory.

Breeding Goal

Recreate the Cali Kush clone-only cut in stable seed form.

Selection Focus

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

Pollen / Mother Source
