Many people mistakenly believe that the best way to turn cannabis purple is to deprive their plants of oxygen. However, depriving your plants of oxygen, carbon dioxide, or any other gas will not improve your chances of harvesting purple buds. Feeding your plants more nitrogen also won’t change the colour of your plants, at least not unless you overdo it and end up burning them to a crispy shade of brown.
Purple weed is real eye candy. And while there are many rumours circulating the internet about how to grow purple cannabis at home, there are really only two variables that you can play with to manipulate the colour of your weed. Keep reading to find out what they are.
Genetics are going to have the biggest impact on the final colour of your plants. So, if you’re set on growing purple weed, shop around for purple strains, as they’ll have been specifically bred for their unique colour. Remember that your buds are going to lose some colour after trimming, so opt for strains with the most vibrant purple pigmentation you can find.
Remember, the two main factors affecting the colour of your cannabis plants are genetics and temperature. If you’re really set on growing purple weed, make sure to invest in the right genetics from the get-go.
• Calyxes: Calyxes are the small pods that make up your buds. Cannabis flowers are actually made up of hundreds of these small calyxes stacked on top of one another. As the flowers mature, the calyxes open and reveal their pistils, which are designed to catch pollen from male cannabis plants.
There are four main parts of your cannabis plant that can turn purple:
Purple Queen is an almost pure indica variety bred from Hindu Kush and Purple Afghani genetics. She flowers over 9–11 weeks and produces big, purple buds with a uniquely pungent aroma that combines hints of both pine and fuel. Purple Queen also boasts a THC concentration of up to 22% and produces a nice, relaxing body stone that’s perfect for whenever you need to unwind and relax.
However, plants also have many other active pigments, including carotenoids and anthocyanins. In the absence of chlorophyll, plants may use pigments like anthocyanins to absorb sunlight and photosynthesise. Unlike chlorophyll, anthocyanins naturally absorb all wavelengths from the sun except those in the indigo spectrum, which is what gives plants their purple colour.
All plants have naturally occurring pigments. The most dominant pigment in most plants (including cannabis) is chlorophyll, which, apart from helping plants photosynthesise, also gives them their green colour.
Perhaps you've seen brilliant purple bud. Perhaps you've even accidentally grown it. Now, you'd like to do it on purpose. Here is the ultimate guide to making your bud glow with that unique purple hue.
Anthocyanins are part of a larger class of substances known as flavonoids, which aside from how the name sounds, have very little to do with flavor (and are astringent to the taste). In fact, the “flav” in flavonoids comes the Greek word for yellow, flavus.
According to the European Food Safety Authority, there is no substantive evidence anthocyanins have any effect on human biology or diseases – though they contain a higher concentration of anti-oxidants, which would theoretically only be beneficial if one were eating buds. There is some minor proven correlation to anthocyanins as an anti-inflammatory, but again, would probably be more active if ingested. Seeking a strain with higher CBD content would be a better source for anti-inflammatory effects than purple hue.

Anything beyond breeding could detriment the plant. “Any energy the plant spends pushing out that purple pigment is going to be drawn from somewhere else and is going to hurt overall. It’s just not worth risking the quality for a chance a slightly better bag appeal.”
Furthermore, no one is wrong to feel that the visual appeal of a flower can enhance the smoking experience. However, ultimately, the mere presence of the pigment is unrelated to the resulting effects. If the flower is good, by all means smoke it, in any spectrum of the rainbow.
This can be a bit linguistically confusing; a blue-named class of molecules that presents as red or purple is a subset of a class of yellow-named molecules. It begins to make sense when we consider that a complex interaction of anthocyanins and other flavonoids is what causes leaves to change their color among such a brilliant spectrum in the fall.
When cannabis presents as purple, we are seeing a similar phenomenon as fall leaves, allowing purple bud to have a wide spectrum as well. Like other plants for cannabis, colors, and changes in color, have purpose. The stressed plant is changing pigment in order to achieve a goal before wilting in the cold, such as conserving energy or increasing chances for pollination.
Consider that what we call a blueberry is also usually quite purple. This is because the very thing that makes blueberries “blue” is the same as what makes purple nugs “purple,” anthocyanins. Anthocyanins are water-soluble pigments present in many plants. Despite the “cyan” in “Anthocyanins” referring to their blue nature, these molecules occur in a range of colors from red to purple to dark blue, or black, depending on pH level.
Purple cannabis can be a tricky concept. Just stop for a moment and contemplate the timeless line, “roses are red, violets are blue.” A modern sensibility would correct that the color of violets is none other than violet. Similarly, purple weed is not always “purple.” It can have a wide range of presentation, from dark green to even black.
