Purple

Purple Feminised Cannabis Seeds by Pyramid Seeds

Purple is a 50/50 indica-sativa hybrid from Pyramid Seeds that delivers vibrant purple buds, mouth-watering berry flavours, and a balanced high — all from a compact, low-maintenance plant. With 15% THC, a 60-day flowering period, and yields up to 450g/m² indoors, she's one of the most visually striking strains you can grow without needing expert-level skills.

Why Grow Purple Cannabis Seeds?

Plenty of strains claim purple colouring, but most deliver a few dark streaks at best. Purple by Pyramid Seeds was specifically selected from a photoperiod phenotype that expresses genuinely vibrant purple hues across the buds — not just a tinge, but proper, deep colour that makes your grow room look like something out of a botanical magazine. We've seen a lot of "purple" strains come through over the years, and this one actually delivers on the name.

Beyond the looks, she's a proper grower's plant. The 50/50 indica-sativa genetics keep her compact — 70 to 120cm indoors — so she fits comfortably in a standard tent without training acrobatics. The buds are dense, tight, and absolutely caked once they mature. And because Pyramid Seeds feminised these seeds, you're not wasting weeks identifying and culling males. Every seed you plant is a potential harvest.

The honest limitation? At 15% THC, she's not going to floor anyone. If you're chasing face-melting potency, look at something like the Tutankhamon from the same breeder — that one pushes past 30%. But if you want a strain you can actually enjoy throughout the day without writing off the afternoon, Purple hits a sweet spot that a lot of high-THC varieties simply can't.

Purple Feminised Seeds — Flavour and Effect Profile

The smoke is where Purple really earns her keep. Crack open a cured jar and you get ripe berries and sweet fruit — not synthetic candy sweetness, but that genuine, rounded fruitiness that makes you want to take another pull. The exhale is smooth, with a lingering berry aftertaste that sits on the palate. If you've ever grown a Blueberry or a Frisian Dew and loved the flavour profile, Purple plays in the same league.

The effect is textbook balanced hybrid. The indica side brings a full-body relaxation that loosens you up from the shoulders down, while the sativa genetics keep your head clear and your mood lifted. It's the kind of high that works equally well on a lazy Sunday or a social evening — present enough to notice, gentle enough to function. The 15% THC means the effect builds gradually and holds for a good while without tipping into couch-lock territory.

According to research published in PMC, anthocyanins — the pigments responsible for purple colouration in cannabis — are biosynthesised through specific genetic pathways, with compounds like delphinidin contributing to the deep violet hues (Guillem-Amat et al., 2023). The colour isn't just cosmetic; it's a marker of the plant's unique phytochemical expression.

Growing Purple Feminised Seeds — What to Expect

Purple adapts to most growing setups without drama. She's not fussy about medium — soil, coco, hydro all work. The compact stature (70–120cm indoors) makes her a natural fit for smaller tents like a 60x60 or 80x80, and she responds well to SOG setups where you want uniform canopy height.

The flowering period runs 60 days from the flip to 12/12, which is quick for a strain producing this kind of density and colour. The purple pigmentation tends to show up in the final two to three weeks of flowering, especially if nighttime temperatures drop a few degrees — not essential, but it intensifies the colour expression.

One thing to watch: those compact, dense buds can hold moisture. Good airflow during late flowering is critical. A small oscillating fan aimed at the canopy and proper extraction will keep you safe from mould. We've seen growers lose beautiful purple colas to botrytis in the final week because they skimped on ventilation. Don't be that grower.

Indoor vs Outdoor — Purple Cannabis Seed Yields

Under a 600W light indoors, expect around 450g/m² from Purple. That's solid for a compact plant with a 60-day flower cycle — she's efficient with the space and light she gets. Run her in a 1x1m tent with four plants in 11-litre pots and you'll fill the canopy nicely.

Outdoors is where she really stretches her legs. In a good Mediterranean-style climate with plenty of direct sun, Pyramid Seeds rates her at 500 to 1000g per plant. That's a wide range, and your results will depend heavily on pot size, feeding schedule, and how much direct light she gets. A plant in a 50-litre fabric pot with full sun will massively outperform one tucked in a shady corner. She finishes in mid-September, which is early enough to avoid the worst of the autumn rains in most of northern Europe.

How to Grow Purple Feminised Cannabis Seeds

1. Germinate your Purple seeds using the paper towel method or directly in a starter plug. Keep the environment warm (22–25°C) and moist. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their final containers once the first set of true leaves appears. For indoor grows, 7–11 litre pots work well given her compact stature.
3. Maintain an 18/6 light cycle during vegetative growth. Purple doesn't need a long veg period — 3 to 4 weeks is enough for most setups, given she'll stretch a bit during early flowering.
4. Flip to 12/12 to trigger flowering. Mark your calendar: 60 days from the flip is your target harvest window.
5. During the final 2–3 weeks, allow nighttime temperatures to drop to 15–18°C if possible. This encourages the anthocyanin production that gives Purple her signature colour. It's not required, but the visual difference is noticeable.
6. Monitor humidity closely once buds fatten up. Keep relative humidity below 50% during late flowering to protect those dense colas from mould. Good airflow is non-negotiable.
7. Harvest when trichomes show mostly milky-white with a few amber heads. Dry in a dark, well-ventilated space at 18–20°C for 7–10 days, then cure in glass jars for at least two weeks. The berry flavour intensifies significantly with a proper cure.
