How to Grow Star Killer Regular
Star Killer Regular is a potent, award-winning indica hybrid that crosses Skywalker OG with Triangle Kush. A Cannabis Cup 2014 winner, it carries a smooth 15–20% THC, a citrus-fruity-kush flavour and a high yield, finishing in 8–10 weeks. It leans 70% indica, with a happy, relaxing, uplifting character. As a regular strain, it gives you both male and female plants, which makes it a favourite for breeding.
Its Cannabis Cup 2014 win is a mark of real pedigree: Star Killer took the resinous Skywalker OG and the OG backbone of Triangle Kush and turned them into a frosty, flavourful plant. That award-winning quality is a big part of why it remains a go-to for growers who want to preserve or breed with elite OG genetics.

Climate and Where to Grow It
Star Killer Regular suits a temperate climate with warm, mild days and a reliable season. Grown outdoors it finishes around October, so pick a region that stays warm and dry into autumn to let its dense, resinous buds ripen fully before the damp arrives.
Its indica lean keeps the plant compact and bushy at around 1.5 m, but the sticky, OG-style colas can trap moisture, so keep humidity moderate and the airflow steady through flowering to protect them from bud rot. A tidy, well-ventilated space helps the whole plant ripen evenly.
Indoors it is happy at daytime temperatures around 68–80°F (20–27°C). A little space around the plant and some gentle training keep light reaching the lower buds, which helps that high yield come in evenly across the canopy.
Working with Regular Seeds
Because these are regular seeds rather than feminized, Star Killer Regular produces both male and female plants. That is exactly what you want if you plan to breed or preserve these award-winning OG genetics, but it does add one job to the grow.
Watch for the first signs of sex in early flowering, usually a week or two after the 12/12 flip: females show fine white hairs (pistils), while males form small round pollen sacs. If you are growing for buds, identify and remove the males before they open and pollinate your females. If you are breeding, keep a strong male to pollinate a chosen mother. This small step is the trade-off for the breeding freedom regular seeds give you.
Growing Basics
Star Killer Regular is a photoperiod strain, so you control the cycle with the lights. Run a vegetative stage under long days, usually 18 hours of light, then switch to a 12/12 light schedule to trigger flowering.
Its indica-leaning structure takes well to a little topping and low-stress training during veg, which spreads the canopy and opens up the lower bud sites. That even canopy is part of how it reaches its high yield from a manageable 1.5 m frame.
Feeding Schedule (EC Guide)
Feed to the stage rather than the calendar, starting low and building up as the plant asks for more. The EC values below climb from a gentle seedling feed to a stronger bloom feed, then drop back for the flush.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Raise nitrogen gently under 18-hour days |
| Early flower | 1.2–1.4 | After the 12/12 flip, shift toward P and K |
| Full flower | 1.4–1.6 | Peak bloom feed while the colas fatten |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering Time and Harvest
After the flip to 12/12, Star Killer Regular flowers in 8–10 weeks. It is a genuinely high-yielding plant and one of our high-yielding options: expect 1.31–1.64 oz/ft² (400–500 g/m²) indoors, with a single outdoor plant bringing in 17.64–19.4 oz (500–550 g).
The strong indica lean builds dense, resinous, OG-style flowers. Harvest when most trichomes have turned cloudy with a few amber for the fullest, most relaxed expression, and give the plant a 1–2 week plain-water flush beforehand to clean up the final flavour.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. With buds this dense, a slow, even dry keeps the inside from staying damp while the outside dries, protecting both the aroma and the resin.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure sharpens the citrus top notes, deepens the kush base and smooths the smoke, which is exactly what a Cannabis Cup winner deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Star Killer Regular is a frosty, resin-coated plant, so the trim is great for dry sift, bubble hash or rosin, giving you a bonus run of concentrate from material most growers throw away.
Flavor and Terpenes
Star Killer Regular tastes of bright citrus and sweet fruit over a classic kush base, the OG-meets-citrus profile it inherits from Skywalker OG and Triangle Kush. The citrus and fruit lead, grounded by an earthy, resinous kush depth.
Of its many terpenes, six lead the character: limonene (the bright citrus note), citral (a sharp lemon lift), terpinolene (fresh and fruity), terpineol (a soft citrus-pine floral), linalool (gentle floral sweetness) and borneol (an earthy, camphor-like note that feeds the kush side). Behind them sit cedrene, camphene, eugenol, fenchol, nerolidol and phytol, a broad supporting cast that rounds out the citrus, fruity, kush profile.
Effects and Best Use
With its 70% indica genetics, Star Killer Regular is reported as happy, relaxed and uplifted, a mood-lifting character with a settled, body-forward edge. It lifts the mood before easing into a mellow relaxation, which keeps it balanced rather than heavy.
With its medium 15–20% THC it stays approachable rather than overwhelming, so it is easy to enjoy. Combined with its award-winning citrus-kush flavour and its high, breeding-friendly genetics, it is a rewarding plant for growers who value both quality flower and a male to work with.
Common Problems and Pro Tips
Star Killer Regular is a rewarding, award-winning grow, but it is a dense OG indica with regular genetics, so plan for the males and the stretch.
- Sort the males early: as a regular strain it produces both sexes, so check pre-flowers and pull the males early unless you are keeping one for breeding.
- Manage the OG stretch: its Skywalker OG and Triangle Kush roots reach up early in flower, so train the tops or give extra headroom to keep the canopy even.
- Watch the humidity: as a 70% indica its buds are dense and trap moisture, so keep flowering humidity down and run a fan to prevent bud rot.
Expert tip: this Cannabis Cup winner carries elite OG genetics worth preserving. The bright citrus and sweet fruit over a kush base holds up best with a slow dry and a careful cure.
Frequently Asked Questions
Has Star Killer won any awards?
Yes. Star Killer is a Cannabis Cup 2014 winner, a mark of its quality and one of the reasons its elite OG genetics are so sought after. That pedigree is part of why growers seek out the regular format, so they can preserve and work with this proven, award-winning line at home.
Are Star Killer Regular seeds feminized?
No. These are regular seeds, so they produce both male and female plants. If you are growing for buds, identify and remove the males in early flowering; if you are breeding, keep a male to pollinate a mother. Check the pre-flowers early so you catch the males before they shed pollen.
Is Star Killer indica or sativa?
It is indica-dominant, at 70% indica and 30% sativa, so the effect is relaxed and body-forward with a happy, uplifting lift. That indica build comes with an OG-style stretch early in flower, so train the tops to keep the canopy even while the dense buds fill out through bloom.
How long does Star Killer Regular take to flower?
About 8 to 10 weeks after the flip to 12/12. Grown outdoors in a temperate climate it finishes around October. Its buds are dense, so keep a fan moving air through the canopy across that window and check trichomes toward the end to catch the plant at your preferred ripeness.
What does Star Killer Regular taste like?
Expect bright citrus and sweet fruit over a classic kush base, driven by its limonene, citral, terpinolene and terpineol terpenes. Dry slowly in a cool, dark space and cure in jars so that fresh citrus over resinous kush character comes through at its best in the finished flower.
How much does Star Killer Regular yield?
It is a high producer: 1.31 to 1.64 oz/ft² (400 to 500 g/m²) indoors, and 17.64 to 19.4 oz (500 to 550 g) per plant outdoors in a good season. Training the OG stretch into an even canopy and good light help it reach the top of that range at harvest time.
