purple weed strains

There’s something about the deep indigo hues of purple bud that stirs up wonder and delight inside every keen marijuana grower. The color transformation is enough to make any of us giddy, but what’s even better are the delicious flavors and mind-bending potency that many of these well-bred purple weed strains exhibit.

Now, despite their dazzling exterior and exciting reputations, are purple marijuana strains some sort of superior weed species – or are they just oxygen-starved cannabis plants begging for better conditions?

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

What Makes Weed Purple?

what makes weed purple

To start off, no, purple weed strains don’t turn purple because of some hidden deficiency or imbalance. The reason why some strains of weed can turn purple and others don’t is simply genetic, due to special components called anthocyanins.

Anthocyanins are grouped in a category of molecules called flavonoids which, despite how they sound, affect the pigment of plants without affecting flavor. This particular flavonoid has the ability to turn plants a range of colors including red, blue, black, and, you guessed it, purple.

Along with some purple marijuana strains, other plants that contain these fascinating flavonoids include raspberries, blueberries, and black rice. Whether the plant or fruit will turn red, blue, purple, or black comes down to the pH in the soil and of the plant in general. More acidic plants will turn red, more alkaline plants will turn blue, and neutral acidity plants turn purple.

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 the anthocyanin levels rise. As this happens, the leaves, stems, and flowers of purple cannabis 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 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 purple cannabis strains, it’s no surprise that their luscious-looking purple bud has 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, purple cannabis 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 often also 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 purple weed strains does take a bit of skill to get the best out of the purple color. Some might argue that allowing your weed plant to mature longer in order to produce a more pronounced hue will, in turn, result in more matured, pungent flavors and smells, making for better bud – but we’ll leave that for you to decide!

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 💜
