Purple Kush Strain Autoflower SeedsOakland's grape-scented pure indica, now on an autoflower clock
No reviews yet · be the first to review Purple KushThe Purple Kush strain is a pure indica from the Oakland area of California, a cross of Hindu Kush and Purple Afghani known for grape-scented buds that often turn violet. This autoflower version adds ruderalis genetics, so the plants start flowering by themselves and are usually ready about 8 to 11 weeks after the seed sprouts. They stay short and bushy, which suits small tents, balconies and quick outdoor runs.

What is the Purple Kush strain?
Purple Kush is a pure indica from the Oakland area of California, bred from Hindu Kush and Purple Afghani, and this autoflower version crosses it with ruderalis so it blooms without any change in day length. Its original breeder has never been documented. Auto listings put the plant at about 60–100 cm indoors with harvest roughly 8 to 11 weeks from seed, while the photoperiod Purple Kush is listed at about 19% THC on Leafly and 22% on AllBud.
AllBud and Leafly class photoperiod Purple Kush as pure indica, though Leafly notes some phenotypes show sativa influence. The auto's ruderalis share is not published.
Many Purple Kush plants turn deep purple as they ripen, a trait tied to the Purple Afghani side, though color varies with the plant and night temperatures.
Purple Kush strain specs
Purple Kush's background (parents, origin, potency, effects) comes from Leafly, AllBud and Weedmaps, which describe the photoperiod strain. The timing, height and yield rows come from seed banks that sell an autoflower Purple Kush, such as Buddha Seeds. Auto lines differ between sellers, so every grow figure is a reported range rather than a fixed spec.
| Type | Indica autoflower; the photoperiod parent is listed as pure indica |
|---|---|
| Genetics | Purple Kush (Hindu Kush × Purple Afghani) × ruderalis |
| Bred by | Original: unknown breeder, Oakland area of California; auto versions by several seed banks |
| THC | Photoperiod Purple Kush about 19% (Leafly) to 22% (AllBud); auto sellers claim up to about 20–22% |
| CBD | Low, under 1% |
| Main terpenes | Myrcene, caryophyllene, pinene, linalool |
| Aroma & flavor | Grape, sweet berry, earthy kush, spice, floral pine |
| Reported effects | Relaxed, happy, sleepy, euphoric, hungry |
| Seed type | Autoflower feminized (female plants) |
|---|---|
| Seed to harvest | Roughly 8–11 weeks (Buddha Seeds: 10–11; most other sellers: 8–10) |
| Outdoor harvest | Sow from late spring; plants finish in under three months, so warm regions can fit two runs |
| Height | Indoors roughly 60–100 cm (2–3.3 ft); outdoor plants can reach about 1.5 m (5 ft) |
| Yield | Indoors about 300–400 g/m² (1–1.3 oz/ft²); outdoors roughly 30–100 g (1–3.5 oz) per plant on seller figures |
| Difficulty | Easy to moderate |
| Best methods | LST, Sea of Green, sow in the final pot |
| Climate | Indoors, or any temperate garden with a sunny summer |
Where does the Purple Kush strain come from?
Purple Kush came out of the Oakland area of California, where a Hindu Kush female was crossed with a Purple Afghani, and no breeder has ever been confirmed. Weedmaps links the classic Northern California cut to Oakland's Oaksterdam scene and says it was spread by Dark Heart Nursery, and Leafly describes the result as a pure indica with four known phenotypes, three of which show some sativa influence.
The autoflower version keeps that Purple Kush base and adds Cannabis ruderalis, a short-season type whose flowering is triggered by age, not night length. Each seed bank makes its own cross, so autos sold under the Purple Kush name are not all identical: Buddha Seeds lists its version as purple and kush lines with ruderalis, and Weedmaps notes one seed company whose Purple Kush Auto uses different parents altogether.
How is Purple Kush Auto different from photoperiod Purple Kush?
Purple Kush Auto usually begins to bloom by itself three to four weeks after sprouting, while photoperiod Purple Kush only blooms once nights reach about 12 hours. The autoflower stays smaller, around 60–100 cm indoors, and runs from seed to harvest in roughly 8 to 11 weeks, close to the 8 to 9 weeks the photoperiod plant spends in bloom alone after its separate vegetative stage.
Expect smaller harvests per plant. Purple Kush Auto trades some yield for speed and a compact frame, so growers often run several plants side by side instead of one large one.
What do Purple Kush buds smell like, and what is the high like?
Aroma and flavor
Purple Kush smells of sweet grape and dark berries over an earthy, hashy kush base, with spicy, woody and floral notes on some plants.
- Grape
- Berry
- Earthy
- Sweet
- Spice
- Pine
Terpenes
- Myrcene
- Earthy and fruity; first on most listings
- Caryophyllene
- Peppery spice under the grape
- Pinene
- A faint pine and resin note
- Linalool
- Floral, lavender-like; named on auto listings
Published Purple Kush terpene lists come from the photoperiod strain and seller descriptions; an auto line may rank them differently.
Reported effects
Purple Kush is usually described as deeply relaxing and sleepy, with a happy, euphoric mood that settles into the body. Leafly rates it mostly calming, and Weedmaps users most often pick happy, relaxed and sleepy.
- Relaxed
- Sleepy
- Happy
- Euphoric
- Hungry
Purple Kush reviewers mention heavy drowsiness and the munchies most often, along with dry mouth; one AllBud reviewer noted a little anxiety.
Purple Kush effect reports here come from reviews of the photoperiod strain on Leafly, AllBud and Weedmaps, and the auto is expected to feel similar. Each person reacts in their own way; nothing here is medical advice.
How do you grow Purple Kush seeds?
Purple Kush autoflower seeds reward a simple plan: sow each seed where it will finish, give it 18 to 20 hours of light every day until harvest, bend rather than cut branches during the first month, and expect ripe buds 8 to 11 weeks after the sprout appears.
- GerminateDays 1–7
Plant Purple Kush Auto seeds in the container they will finish in, around 11–19 L (3–5 gal), so the roots are never disturbed.
- Early growthWeeks 2–4
Bend the main stem sideways with soft ties; Purple Kush grows short and bushy, so a little LST is enough to open the center.
- FlowerWeeks 4–9
Buds form without any change to the light. Keep humidity down, because Purple Kush packs tight, dense flowers.
- HarvestWeeks 8–11 from seed
Check the trichomes before cutting; purple color can appear before the buds are ripe, so judge by resin rather than color.
Grow tips for Purple Kush
- Don't judge the plant by its color. Some Purple Kush Auto plants stay mostly green; Weedmaps notes that violet color depends on genetics and conditions, so a green plant is not necessarily the wrong strain.
- Open up the dense foliage. Purple Kush has thick indica leaves and tight buds, so remove a few large fan leaves that shade bud sites and keep a fan moving air across the canopy.
- Avoid late high-stress training. Purple Kush Auto has only a few weeks before it flowers, and heavy cuts after week 3 can stall it; bend branches with LST instead.
- Plan for a strong grape smell. Growers of Buddha Seeds' Purple Kush Auto report a strong grape scent by harvest, so run a carbon filter if odor matters.
- Fill small spaces with several plants. At about 60–100 cm, Purple Kush Auto fits closets and small tents; a Sea of Green with several plants fills the floor faster than one big plant.
- Stagger outdoor sowings. With a life cycle under three months, Purple Kush Auto can be sown from late spring for a summer harvest, with a second batch started afterward in warm climates.
Is Purple Kush the right strain for you?

- Prefer an energetic daytime high
- Plan to keep mother plants and take clones
- Want the photoperiod Oakland cut exactly as it was
Purple Kush strain FAQ
Is Purple Kush Auto indica or sativa?
Purple Kush Auto is an indica autoflower. Its photoperiod parent, Purple Kush, is classed as pure indica by AllBud and Leafly, and the auto version adds ruderalis genetics so it flowers on its own. Leafly notes that some Purple Kush phenotypes show a little sativa influence.
How many weeks does Purple Kush Auto need from seed?
Most Purple Kush Auto listings say 8 to 10 weeks from seed, and Buddha Seeds lists 10 to 11 weeks for its version. Plan on about 8 to 11 weeks in total, depending on the line, your light and your growing conditions.
Does Purple Kush Auto need a 12/12 schedule?
No. Thanks to its ruderalis genetics, Purple Kush Auto blooms once it reaches a certain age, not when the nights get longer. An 18/6 or 20/4 schedule for the whole grow is the usual choice for this strain.
How tall does Purple Kush Auto grow?
Purple Kush Auto stays short: seed banks list about 60–100 cm (2–3.3 ft) indoors and up to about 1.5 m (5 ft) outdoors. Its bushy indica shape makes it easy to fit under a small grow light or in a balcony pot.
What are Purple Kush's parents?
Purple Kush is a cross of Hindu Kush and Purple Afghani, both indica lines, made in the Oakland area of California by a breeder who has never been identified. The autoflower version crosses Purple Kush with ruderalis.
How much THC does Purple Kush Auto have?
Photoperiod Purple Kush is listed at about 19% THC on Leafly and 22% on AllBud. Seed banks claim up to about 20–22% for their auto versions, but no independent test of the auto is published, so read those figures as upper estimates.
Will Purple Kush Auto turn purple?
Often, but not always. Purple Kush gets its color from its Purple Afghani parent, and many plants turn violet late in flower. Color depends on the individual plant and on conditions such as night temperature, so some stay mostly green.
What does Purple Kush taste like?
Purple Kush tastes of sweet grape and berry over an earthy kush base, with a touch of spice and pine. Myrcene and caryophyllene lead its published terpene profiles.
How much does Purple Kush Auto yield?
Buddha Seeds lists up to 400 g/m² indoors and up to 100 g per plant outdoors for its Purple Kush Auto under ideal conditions, while another seller gives about 300 g/m². Compact autoflowers like this yield less per plant than photoperiod Purple Kush.
