Purple cannabis seeds are a family of strains — indica, sativa, and hybrid — that throw violet, lilac or deep-grape hues in the flower when night temperatures drop. Azarius has been shipping seeds since 1999, and this corner of the catalogue covers five purple-tinged feminized and autoflower options, from berry-heavy GDP to daytime Purple Haze. Buy purple cannabis seeds with genetics you can actually trust.

Purple cannabis seeds produce plants with anthocyanin-rich flowers that turn purple, lilac or near-black as they mature. The colour comes from pigment expression triggered by cooler nights in late flower — it's genetics meeting environment, not a marketing gimmick. Our five-strain range covers feminized photoperiods and autoflowers, indica-leaning knockouts and sativa-forward daytime strains.
Quick honest note before you shop: purple does not mean stronger. It means the plant carries the genes to express anthocyanins. Flavour, potency and effect depend on the full terpene and cannabinoid profile, not the colour. Pick the strain by how you want to feel, not by how pretty the buds look on Instagram.
| Strain | Type | Flowering | Effect profile | Good for |
|---|---|---|---|---|
| Granddaddy Purple | Feminized, indica-dominant | 8–10 weeks | Heavy, relaxed, evening | Growers who want classic purple indica with berry-grape notes |
| Purple Haze | Feminized, sativa-dominant | 8–10 weeks | Creative, energetic, daytime | Sativa fans who want purple hues without couch-lock |
| Purple Haze Auto | Autoflower, sativa-dominant | 8–10 weeks seed to harvest | Uplifting, moderate (14–16% THC) | First-time growers wanting a fast sativa |
| Purple Punch Auto | Autoflower, indica-dominant | ~11 weeks seed to harvest | Knockout relaxation, dessert flavour | Forgiving autoflower with grape-candy terps |
| Cherry Pie OG | Feminized, 50/50 hybrid | Standard photoperiod | Balanced, 18–25% THC | Growers who want hybrid balance with cherry-diesel flavour |
Read the table by effect first, format second. If you've never grown before, an autoflower is the simpler path — no light schedule to manage, seed to harvest in roughly 8–11 weeks. Photoperiod feminized seeds give you bigger plants and more control, but you'll need to switch the light cycle to trigger flowering.
Start with the effect you actually want. Evening wind-down and sleep? Order Granddaddy Purple or Purple Punch Auto — both indica-heavy, both lean into the grape and berry side of the terpene spectrum. Want something you can smoke at 2pm and still get things done? Purple Haze or Purple Haze Auto keep the colour without the sedation.
Cherry Pie OG sits in the middle — a true 50/50 hybrid for growers who don't want to commit to one end of the spectrum. THC sits between 18% and 25%, and the Cherry Pie × OG Kush cross gives you sweet cherry on the inhale and a diesel backbone you'd expect from OG genetics.
Warm indoor tents with no temperature drop will still grow fine buds, but the colour stays green. If you want the purple to show, you need the genetics and the environment.
Feminized photoperiod seeds (Granddaddy Purple, Purple Haze, Cherry Pie OG) produce only female plants and flower when you switch the light cycle to 12/12. You get more control, bigger yields, and the option to take clones. Autoflowers (Purple Haze Auto, Purple Punch Auto) flower automatically based on age, usually 3–4 weeks from germination, and finish the whole cycle in around 8–11 weeks. Smaller plants, faster turnaround, no light-schedule juggling. For a first grow, we'd pick an autoflower every time.
Anthocyanin pigments — the same compounds that colour blueberries and red cabbage. The genes have to be in the strain, and the plant usually needs cool night temperatures in late flower to express the colour. Green buds from a purple strain still carry the same cannabinoid and terpene profile.
No. Colour and potency are unrelated. Granddaddy Purple and Cherry Pie OG can both push 20%+ THC, but plenty of green strains match or beat that. Buy based on the cannabinoid profile, terpenes and effect you want — not the colour.
Purple Haze Auto or Purple Punch Auto. Both are autoflowers, so you skip the light-schedule switch, and both are forgiving if your environment isn't dialled in. Purple Punch Auto leans relaxing; Purple Haze Auto leans energetic. Pick by the effect you want.
Pretty much, yes. Most purple strains need a 10°C drop between day and night in the final 2–3 weeks of flower to fully express the colour. Warm, stable tents will still produce healthy plants — they'll just stay green. The genetics are there either way.
Most of our purple feminized photoperiod seeds flower in 8–10 weeks after you switch the lights to 12/12. Granddaddy Purple and Purple Haze both fall in that window. Autoflowers run on their own clock and finish the full cycle in roughly 8–11 weeks from germination.
