Reviews and Comparisons of Various Purple Cannabis Seeds


Cannabis is typically associated with deep green colored buds and leaves. But did you know that there are strains that produce grape-like, purple buds? You may have encountered such weed and may be wondering whether these weed types are safe for consumption or how they vary from the typical green buds you’re accustomed to. 

The good news is that purplish cannabis is absolutely safe. Indica buds tend to develop these colored buds, indicating a certain level of terpene content with a potentially relaxing profile. However, this esthetically pleasant purple cannabis flower is surrounded by many misunderstandings and myths concerning its potency, effects, and medical benefits. 

So, if you’re seeking information on why some marijuana varieties have flowers with purple shades ranging from deep plum to violet, you’re in the right place. This article bears the answers to your questions. Let us begin by understanding what the plant is.

What Is Purple Cannabis?

Purple cannabis is quite simply a marijuana plant with flowers that have purple coloration. The purple hue comes from the presence of a category of flavonoid compounds called anthocyanin, which is available in plants such as grapes, plums, and eggplant. While many chemical, genetic, and environmental factors contribute to the plant’s varying hues, it is impossible to induce the purple pigment without a genetic predisposition to purpling. The smell, taste, and color of cannabis also fluctuate as the plant matures. Sometimes the plant may even appear reddish or bluish as it grows and the soil’s pH changes. Other factors that affect pigmentation include changes in temperature and light exposure.

Myths and Facts about Purple Weed Seeds

Several versions of the origin and evolution of the purple cannabis flower circulate on the internet. Most of this information is hinged on what makes the buds purple and how farmers create these hemp strains. For instance, nitrogen is one of the primary macronutrients that cannabis plants require to survive and thrive since it influences plant development and yield quantity and quality. Therefore, some growers believe that applying more nitrogen-rich fertilizers improves the quality of the seed, thus producing better-quality buds. However, research shows that a nitrogen overload results in discoloration of the plant by changing the buds to a brownish color. 

Another skewed belief is that fluctuation of water schedules for the cannabis seeds enhances the purple tone and, consequently, the taste and aroma profile. That myth is disparaged by the fact that the cannabis plant naturally grows in the wild, making it exceptionally resilient and, therefore, unaffected by water availability. 

Other narratives suggest that depriving the cannabis seeds of oxygen or carbon dioxide inhibits the root’s oxygen absorption rate, resulting in purple leaves. However, studies reveal that the deprivation results in a sickly plant with low yields, and the leaves will most likely turn yellow and wither instead of the projected purpling effect. The fact remains that purple flower weed grows from seeds that are genetically predisposed to create such colored plants, and any manipulation is more likely to affect the flower’s health rather than help the grower change the hue.

Now let us take an in-depth look into the various purple weed seeds that are currently dominating the cannabis industry. We will discuss the qualities of the following strains:

  • Purple Urkle 
  • Purple Punch 
  • Purple Haze 
  • Purple Kush 

Purple Urkle Feminized Seeds

This one-of-a-kind Indica-dominant hybrid is a descendant of the award-winning Mendocino Purps cultivar known for clinching the High Times Cannabis Cup. Users love its authentic aroma, a fusion of sweet fruity, tropical, and skunk notes. The buds of this beautiful strain contain high THC levels ranging between 20 – 23%, which bring an energizing and euphoric effect. The feminized Purple Urkle seeds are pretty versatile and thrive in various climatic conditions, although they prefer warm, sunny temperatures. When grown indoors, the ideal temperature to achieve optimum purple hues and the highest bud quality is 72 – 80 degrees Fahrenheit. It is important to note that the strain genetically has high levels of anthocyanin to give it the purple flowers and leaves; therefore, there is no need for temperature manipulation, as is the common myth.

The indoor-grown Purple Urkle feminized seeds start producing flowers within 55 – 60 days of planting, and its crops can grow approximately 12 – 14 oz per square meter compared to the outdoor-grown crop that yields 26 – 35 oz per cultivar. A light cycle of 18/6 enhances the yield capacity, although the seeds are not exactly photosensitive and will still produce in natural light and uncontrolled light cycles when grown indoors. The seeds also grow best in a soilless medium such as rock wool and coco peat.


Purple Punch Feminized Seeds

Like the Purple Urkle seeds, this Indica-dominant hybrid thrives in warm, sunny climates with a preferred indoor temperature range of 70 – 80 degrees Fahrenheit. This crossbreed of Granddaddy Purple and Larry OG gets its name from its stunning purple color and the heavy punch effects on the consumer. Compared to Purple Urkle, it has a lower THC content managing between 15% and 20%. This strain is highly regarded in medical marijuana circles due to its hard-hitting tranquilizing effects, leaving the user couch locked and sedated for approximately 4–5 hours.

The Purple Punch feminized seed is 80% Indica and 20% sativa with photoperiod qualities. This makes it a perfect candidate for indoor and greenhouse farming since it requires keen light cycle monitoring. The seeds also grow well under humidity levels between 40% and 50% to prevent mold and mildew. The seeds are not easy to grow, requiring close observation and constant plant trimming to encourage lateral branching.  


Purple Haze Autoflower Seeds

This legendary strain gained popularity from the Jimi Hendrix song, and it lives up to its hype. The strain’s 60% sativa and 40% Indica genes give a long-lasting high that leaves the user focused and energized, like the previously discussed strains. Like with Purple Urkle, these seeds are easy to cultivate, making them an excellent choice for beginner growers. The seeds produce plants with an incredibly high tolerance to pests, diseases, and mildew owing to their ruderalis gene. The fast-growing, high-yielding seed takes 60–65 days to mature, rising to 70 cm when grown indoors and about 120 cm outdoors.


Purple Kush Autoflower Seeds

This Indica-dominant strain is a highly rated medical-grade marijuana cultivar owing to its power-packing effects. Its properties include a long-lasting, relaxing feeling that keeps the users couch-locked and induces sleep for elongated periods. The seeds are a fusion of Hindu Kush and Purple Afghani, known for producing gorgeous amethyst-colored flowers and buds with a staggering 18–20% THC level and an insignificant CBD content. This feminized autoflowering seed has small nugs with a sweet, herbal scent and flavor, a signature of Kush weed variants. 

The seed is autoflowering, meaning that the plants are not dependent on photoperiod, unlike Purple Punch, and they automatically switch from the vegetative stage to the flowering phase. Purple Kush autoflowering seeds thrive indoors, producing compact-sized cultivars with an estimated 350–400g per square meter yield indoors as compared to the 50–60 g per plant outdoors. 



Apart from producing breathtaking colored buds, purple cannabis seeds come with several unique properties. They are highly resilient, fast-growing seeds that are easy to maintain. From what we have analyzed, they produce valuable crops with incredible effects. It is worth noting that the flavors, aromas, and effects of purple cannabis differ depending on the specific strain, growing conditions, and the mode of their consumption.
