About Rockstar Kush Feminised

The way to plan Rockstar Kush is backwards from the day you intend to cut, with up to 400 g/m2 per square metre indoors and up to 450 g/plant per plant outdoors as the figures you are working toward, at 18% THC. Count 60-65 days back from that date and you have your flip date. Most of the final weight lands between weeks 5 and 8, when calyxes stack fastest and trichome cover goes from patchy to complete. Outdoors in the Southern Hemisphere you want that fattening phase falling in February while the days are still long, which puts a late-March cut about right for most of the country.

Where the Weight Actually Comes From

Yield on Rockstar Kush — the up to 400 g/m2 indoors and up to 450 g/plant outdoors quoted above — is decided in three short stretches of the 60-65 days 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 is modest at 20-30%. Strip the lower fan leaves around day seven and that energy goes into bud sites instead.

Weeks three to five. This is when caryophyllene 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 15-20% amber for the heavy end of what this genetics does. Outdoors that usually lands between late March and mid-April.

Difficulty: intermediate. In flower for 60-65 days. Stands 70–110 cm. Indoors it returns up to 400 g/m2. Outdoors, up to 450 g/plant a plant.

Aroma, Flavour and Effect

The first thing Rockstar Kush does at 18% THC is settle a warm peppery spice at the back of the throat. The relaxed, sleepy, happy effects follow within minutes, starting as weight behind the eyes and working down through the shoulders and limbs. Fifteen minutes in there is a physical stillness — not sedation so much as a disinclination to get up. Two to three hours at a moderate dose. Myrcene sits underneath all of it, adding more body, reinforcing the physical side.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Bisabolol underneath. Read across a cure, these three compounds do not stay in the same order. Fresh off the dry, caryophyllene leads. After three or four weeks in sealed glass at 16-18°C the bisabolol undertone comes up and the bouquet gains a layer it did not have at harvest. Vaporising between 180°C and 195°C captures the widest span of them — run it hotter and the volatile bisabolol molecules are the first thing you lose.

Suitability and Recommendations

Who does well with Rockstar Kush? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated intermediate, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions. Sent nationwide in plain, unbranded packaging, with sourced grow data on every strain page.

Stabilisation Notes — What This Means for Your Grow

Rockstar Kush began life as a clone-only cut. Translating a clone into seed without losing the bud-to-leaf ratio demands backcrossing — we crossed our chosen pheno back to the parental line three times (BX3) to fix the elite mother into stable seed form.

Breeding Goal

Translate a clone-only 2010s production cultivar to seed without losing the mother profile.

Selection Focus

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