Sometimes, only leafs turn purple, while other times perhaps we only find purple pistils or buds. Of course, we can also find completely purple phenotypes, both leafs and buds.
Except in specific cases, these beautiful colors are only shown at the end of bloom, so plants remain green during growth and early stages of the flowering period.
Some cannabis strains are especially known for acquiring beautiful colours, normally at the end of the bloom stage.
Proper flushing of nutrients at the end of bloom also allows the plant to show its most beautiful colours while improving the quality of the harvest.
Purple marijuana strains
Each seed produces a unique individual – phenotype – so it should be noted that it is possible to find purple plants and green plants among seeds from the same strain.
Despite colour is a genetic trait, it can also be subject to environmental factors like cold temperatures at the end of the flowering period. Low temperatures promote the production of anthocyanins, the family of vegetable pigments responsible for the colour of blueberries, blackberries, cherries, black grapes, eggplants, etc.
Unlike others, which develop yellow-brown colours when chlorophyll degrades, some genetics acquire purple, bluish, reddish and even black hues.

During the fall months, the green pigments tend to break down and this is when anthocyanin begins to take its effect. This is when getting the right DIF (Differential temperature) enables the plant to turn purple. Ideally, the difference between day and night temperatures should be 30 degrees. This means that if your daytime temperature is 80, the night temperature should be set to 50. The ideal night cycle temperature during the flowering period is believed to be below 10 degrees Celsius or 50 degrees Fahrenheit.

STEP 1: Choosing the Right Cannabis Seeds
Some growers, knowingly or unknowingly, make the mistake of inducing purple color by depriving the plant of oxygen, carbon dioxide or increasing the nitrogen levels. This rarely works and you are more likely to lose your crop instead of getting a purple color. Some people also try artificial methods such as food coloring to dye the plant and hoping for the best. Needless to say, this is not a good reliable or long term approach. Changing the light levels or the amount of water for the plants is also not a great way to achieve purple strains.
When the days become shorter during the winters, the natural process of photosynthesis is slowed down as light-dependent plants are signaled to stop producing chlorophyll. If the timing is right, the flowering period coincides with the dissipation of chlorophyll from the plant which allows the anthocyanins to kick in and impose their color on the cannabis strains.
The first and, without a doubt, the most important part of growing purple cannabis strains is selecting the correct seed. To achieve purple hue, the seeds must have the genetic ability to produce anthocyanin, the pigment that gives the purple color to plants in the later stages of cultivation.
The Science Behind The Purple Color
Whether you are trying to grow purple cannabis for personal reasons such as to impress your friends or simply to enjoy its distinct taste, or doing it for business reasons and serving the needs of your customers, it is essential to know the right way to grow it. When growing purple strains, you do not only want to achieve the purple color but also want the distinct taste that only a perfectly grown strain can give.
