Last updated: 17 November 2023

best purple weed

There's just something about the dark purple shades of weed that gets growers excited. The way it changes color is enough to make anyone feel giddy, but what's even better is the amazing taste and mind-altering strength that a lot of these well-bred purple strains have.

In this article, we uncover why some strains go deep purple and others don’t, get to the truth about purple cannabis strains, and give you our list of the top purple strains you won’t regret adding to your grow schedule.

What Makes Weed Purple?

what makes weed purple

To start with, the reason why these strains turn purple has nothing to do with any sort of hidden problem or imbalance. It's actually just a matter of genetics – more specifically, thanks to special pigments called anthocyanins.

Anthocyanins are part of a group of chemicals called flavonoids. Even though that sounds fancy, they don't affect the taste of plants, just their color. This particular flavonoid has the power to make plants turn all sorts of colors, like red, blue, black, and yes, you got it, purple.

It's not just marijuana that has flavonoids. Other plants like raspberries, blueberries, and black rice have them too. Whether a plant, fruit, or berry becomes red, blue, purple, or black depends on how acidic the soil and the plant itself are. If it's more acidic, it'll turn red, if it's more alkaline, it'll turn blue, and if it's somewhere in between, it'll turn purple.

purple marijuana strains

Cannabis plants that contain anthocyanin only begin to turn purple toward the end of their growth cycle. This is due to the fact that chlorophyll, the dominant component inside the plant up until this point, begins to lessen as anthocyanin levels rise. As this happens, the leaves, stems, and flowers of purple strains start to gradually change from green (chlorophyll) to purple (anthocyanin).

The amount of anthocyanin released inside a cannabis plant will affect how purple the plant can become. Various environmental and genetic factors also determine how much of the flavonoid is released.

Colder weather, soil nutrition, and maturation length can all affect how much anthocyanin a plant releases, but in some cases, it still might not be enough to change the color of the plant at all. This is why cannabis breeders make sure to breed strains that are able to release enough anthocyanin for the plants to turn beautiful hues of purple every time.

Is Purple Weed Better?

With the rarity and mystical beauty of these iconic purple strains, it’s no surprise that they have a reputation for being superior in more than just appearance. However, unless your favorite color is purple or you get uplifted at the sight of glossy purple buds, these strains are not inherently better.

That being said, purple marijuana strains are rarer compared to traditional green strains, making them a lot more fun to grow, and they produce buds that are sure to impress your friends. These strains are also often bred very well, with emphasis on great flavors and potency to really seal the deal on making your purple bud feel out of this world.

Growing these strains requires some skill to bring out the most intense purple color. Some people might say that if you let your marijuana plant mature for a longer time, it will have a stronger hue and a more potent taste and smell, leading to better buds, but we'll let you be the judge of that!

Benefits of Purple Marijuana Strains

purple weed benefits

Even though there's no solid scientific evidence yet, some people believe that using a purple stain instead of a green one has some awesome and long-lasting effects, including:

  • Antidepressant properties: Purple weed helps ease the impact of feeling down and stressed out when used correctly.
  • Pain relief: Purple strains have chemicals that help with pain, and people who use them for chronic pain are less likely to have issues with using too much.
  • Strong relaxing effects: As purple strains are usually Indica-dominant, they have a strong relaxing effect while being high in THC.

Growing Tips

Growing purple varieties can be quite challenging, even for experienced cultivators. However, the key to doing so successfully lies in understanding their growth habits and requirements. Here are a few things to keep in mind.

  • Know your strain: It's important to know the characteristics of the strain you're working with, whether it's a bushy plant or a tall one. This knowledge will help you determine the best approach for its cultivation. For example, if you're short on space, you might want to consider a low-lying strain like Purple Kush.
  • Give plants enough breathing room: It's crucial to space out your cannabis plants, especially if they're bushy. This allows for proper air circulation, which helps prevent issues like mold and foliar diseases.
  • Let the sun work its magic: The sun is a great source of energy for plants, as it helps them produce vital chemicals and carbohydrates through photosynthesis. If you have a bushy strain, make sure to give it plenty of sunlight or provide it with 8-10 hours of artificial light exposure.
  • Help your plants grow better: Training has been shown to increase the amount of buds that marijuana plants produce, including those with a purple color. You can do this by gently bending and shaping the branches so that the leaves can soak up more sunlight and create more places for buds to grow.
  • Stick to the right fertilization plan: When it comes to strains that produce a lot of buds, they usually need more nutrients. Make sure to give your plants a good dose of fertilizer that has nitrogen, phosphorus, and potassium in it, especially during the growing stage.

Purple weed is so tasty!!!! I like it!!!
The most purple weed strain I ever grew was Black Domina cannabis strain from Sensi Seeds. The whole plants were deep purple to black at the end. I harvested them in December at -5°C. While harvesting I thought there was ice on the buds but turned out it was covered with pure crystals and resin. The high was outstanding 💜
