What’s the Deal with Purple Weed?

Purple weed has always been a favorite among stoners and growers, known for its eye-catching shades from soft lilac to deep violet. This unique coloration doesn’t just make purple weed look good, but it also raises questions about what makes it special and what causes its color.


Lately, there’s been a lot of talk about the benefits of purple weed, its potency compared to other strains, and the science behind its color. With more stoners gravitating towards these varieties, the demand for purple strains has gone up. This has encouraged growers to get better at creating conditions that bring out those sought-after purple traits.


In this blog, we’re going to take a closer look at why purple weed is so appealing, diving into its genetics, the environmental factors that influence its color, and how it differs from the more common green cannabis in both looks and effects.


What Makes Weed Purple?

The beautiful purple color of a purple weed strain isn’t just visually appealing; it’s actually caused by a mix of genetics and environment.


The key to the purple color lies in anthocyanins, a type of flavonoid found in many plants, including cannabis. Anthocyanins are responsible for the red, purple, and blue colors of fruits and vegetables.


The coloration process of purple weed is largely influenced by the plant’s genetics. Some cannabis strains naturally contain higher levels of anthocyanins. However, the visibility of these pigments is also heavily dependent on external environmental conditions, particularly during the flowering stage.


Cooler temperatures can suppress chlorophyll production (the green pigment) and allow the purple pigments to become more pronounced, leading to the striking coloration that makes these strains so distinctive.


Now, anthocyanins do more than just contribute to the plant’s aesthetic appeal; they also offer protective benefits to the cannabis plant. These compounds help shield the plant from various environmental stressors such as ultraviolet light, cold weather, and pests.


In terms of effects on the user, while anthocyanins themselves don’t necessarily enhance the potency of the weed, they are known for their antioxidant properties, which could contribute to the overall therapeutic effects of purple weed flower strains.

The Genetics of Purple Weed Strains

Exploring why some weed strains have attractive purple colors reveals a mix of genetics and precise cultivation.


Some cannabis strains are genetically predisposed to produce more anthocyanins, which gives them their purple color. In the following sections, we’ll look at some of the most popular purple weed strains and the science behind their genetics.


Common Purple Weed Strains

  • Granddaddy Purple: A classic among purple marijuana strains, known for its potent effects and sweet, berry-like aroma. Granddaddy Purple is a staple in the purple weed category, beloved for its deep violet leaves and relaxing effects.
  • Sour Grape: This strain combines the tangy, sour flavor of grape with a visually striking purple hue. Sour Grape is favored for its balanced effects that cater to both relaxation and a gentle euphoric high.
  • Purple Punch: Bearing a dessert-like name, Purple Punch lives up to its moniker with a sweet, fruity taste and a beautiful purple appearance. It’s often sought after for its ability to soothe and relax.
  • Purple Thai: A more vibrant strain that showcases vivid purple streaks against a backdrop of green. Known for its uplifting and energizing effects, Purple Thai is a great choice for daytime use.

Genetic Manipulation vs. Natural Occurrences

The appearance of purple in weed can occur naturally, due to the genetic predisposition of certain strains to produce high levels of anthocyanins.


However, with the growing demand for purple cannabis, some cultivators have turned to genetic manipulation to enhance or introduce purple hues in strains that might not naturally express them. This can involve selective breeding techniques, where strains known for their purple coloration are bred together to reinforce the trait in future generations.


While some purists prefer the natural occurrence of purple weed, advancements in genetic manipulation offer a way to experiment with coloration while potentially enhancing other desirable traits, such as flavor profiles or potency levels.


Growing Purple Weed

To successfully grow purple cannabis, understanding the ideal conditions that bring out its vibrant colors is crucial.


While genetics play a significant role in determining whether a strain can turn purple, specific environmental factors during the growing stage can significantly influence the expression of these colors.


Ideal Growing Conditions

The key to achieving that sought-after purple hue lies in controlling the growing conditions to favor the expression of anthocyanins.


Generally, a stable environment with a careful balance of nutrients, pH level, and moisture is essential for the healthy growth of cannabis plants, including purple strains.


Ideal Temperature

Temperature plays a pivotal role in the development of purple colors in cannabis. During the flowering stage, cooler nighttime temperatures are critical for decreasing chlorophyll production, the pigment responsible for the plant’s green color.


Lower temperatures help to reveal and accentuate the purple pigments by allowing the anthocyanins to become more prominent.


It’s suggested to slightly lower temperatures during the night cycle in the flowering phase but be mindful to avoid extreme cold, as it can stress the plant and affect its growth.


Ideal Lighting

While the type of light doesn’t directly influence color change, the intensity and spectrum can impact the plant’s overall health and its ability to express purple hues.


Full-spectrum LEDs are often recommended for indoor growing as they can be more easily controlled to mimic natural sunlight conditions, which is beneficial for the development of purple colors.


However, it’s the temperature rather than the light that plays a more direct role in color expression.

Harvesting Purple Weed

After carefully nurturing the purple cannabis through its growing cycle, ensuring a timely and proper harvest is paramount to preserve its unique coloration and potent qualities.


Identifying the right time to harvest purple weed involves observing the trichomes, which are the tiny, crystal-like structures on the buds. When most trichomes shift from clear to a milky white color, it’s a strong indicator that the cannabis has reached its peak potency.


For strains with purple hues, the coloration of leaves and buds will be visibly richer and more pronounced, showcasing various shades of purple that signal readiness for harvest.


How to Preserve Purple Strains While Harvesting

To maintain the vibrant purple coloration and quality of the buds during harvest, it’s important to handle the plants gently and to dry and cure them properly.


Careful trimming should be practiced to keep as much of the purple leaves intact as possible.


Slow and controlled drying, followed by a thorough curing process in air-tight containers, will not only preserve the purple hues but also enhance the overall aroma, flavor, and potency of the purple buds.


Avoid rushing the drying process as rapid moisture loss can diminish the visual appeal and quality of the final product.


Cultivating Purple Weed: Tips and Tricks

For succthe ssful growth of purple weed, it’s crucial to carefully manage soil nutrients and the pH levels of the growing medium. These factors significantly affect the plant’s natural purple colors, resulting in a more vibrant harvest.


Soil Nutrients and Additives That Enhance Purple Hues

Adding specific nutrients and supplements to the soil can really bring out purple colors in cannabis plants.


Key nutrients like potassium, phosphorus, and magnesium are vital for the plant’s health and for making anthocyanins, which give the plant its purple hue.


Using organic supplements like bat guano, bone meal, and Epsom salts is a great way to provide these nutrients. Also, adding sulphur can boost the purple color by mildly stressing the plant, which increases anthocyanin production.


The Importance of pH Levels in Cultivating Vibrant Colors

Keeping the right pH level in soil is crucial for getting the best nutrient absorption, which affects the color of purple marijuana strains.


Cannabis plants do best in a slightly acidic to neutral pH range, about 6.0 to 7.0. If the pH level goes too far off this mark, the plant might not be able to get the nutrients it needs from the soil, which could mess with its color.


To keep those vibrant purple colors consistent, it’s important to regularly check the soil’s pH and adjust it using natural solutions if needed.
