What Makes Cannabis Purple Sometimes? 🟣

When Kentucky medical cannabis patients visit a dispensary, they’re often drawn to purple marijuana. Its striking color makes it stand out in a lineup of green buds, and many wonder: What causes weed to turn purple, and does it make a difference?

I’ll walk you through the science, common myths, and how to find the right purple strains for your therapeutic needs.

Why Cannabis Turns Purple

Cannabis color is influenced by anthocyanins, natural pigments also found in blueberries and eggplants. These pigments can become more prominent when chlorophyll — the green pigment in plants — breaks down, often due to cooler nighttime temperatures.

While temperature is a key environmental factor, genetics play an even bigger role. Certain strains are bred with a higher likelihood of expressing purple hues, especially under the right growing conditions.

Is Purple Marijuana Better?

The short answer: not necessarily.
Quality depends on genetics, cultivation practices, cannabinoid content, and terpene profile — not just color. While purple cannabis can be beautiful and enjoyable, its potency and medical benefits depend on the same factors as any other strain.

Some popular purple strains, like Granddaddy Purple and Purple Kush, are well-known for relaxation and pain relief. Others, like Purple Haze, provide uplifting and creative effects. But plenty of green strains offer equal or greater therapeutic value.

Factors That Influence Color and Quality

Several elements determine both the hue and the quality of cannabis:

• Genetics – Certain cultivars naturally produce anthocyanins.

• Temperature – Cooler nights (50–60°F) can enhance purple tones.

• Nutrients – Balanced phosphorus and potassium levels help maintain plant health while supporting coloration.

• Light Exposure – Full-spectrum lighting, especially with some UVB, can intensify colors.

• pH Balance – Proper soil or hydroponic pH ensures optimal nutrient uptake.

Terpenes and Flavors in Purple Strains

Purple cannabis often has unique terpene profiles, giving it grape-like, berry, or earthy aromas. These compounds influence more than just flavor — they can also shape the strain’s therapeutic effects. For example:

• Myrcene – Relaxing, sedative qualities.

• Pinene – Alertness and respiratory support.

• Limonene – Mood elevation and stress relief.

This is why two purple strains can look similar but feel very different in their effects.

Notable Purple Strains Found in Dispensaries

Here are a few dispensary favorites that combine color with well-documented effects:

1. Granddaddy Purple (GDP) – Sedating, grape-flavored, ideal for insomnia and pain.

2. Purple Haze – Uplifting, creative, with berry sweetness.

3. Purple Kush – Deep relaxation and sleep support.

4. Purple Punch – Balanced relaxation and euphoria with candy-like notes.

5. Mendo Purps – Mood-lifting, mildly euphoric, with earthy berry flavor.

These strains are widely available in licensed dispensaries and can be delivered to Kentucky patients through approved services.
