A Medical Marijuana Patients Guide to Growing Purple Cannabis



Most medical marijuana patients are used to seeing the color ‘green’ when looking at cannabis buds. However, cannabis buds can also be purple. Purple cannabis is becoming more popular among growers and consumers alike. Some possible reasons for its growing popularity could be because of its high levels of THC compared to other strains and the medicinal benefits it has for consumers. Purple cannabis includes high levels of anthocyanin, which is known to improve cardiovascular health, provide pain relief and act as an antioxidant and anti-inflammatory.


Why the color purple?

Cannabis buds change their colors depending on the environment they are grown in. When cannabis is grown in colder temperatures, naturally the buds will change color. Cannabis buds can transition to the color purple when the pH of anthocyanin in the plant is neutral. The most common way for this to happen is when the plant is exposed to freezing temperatures overnight. Although, it is still possible to obtain purple cannabis in warmer temperatures.


Simple Steps For Growing Purple Cannabis

There is a lot of misleading information on the internet about growing purple cannabis. Some of these ‘quick methods’ include: depriving your plant of oxygen, shocking the plant with freezing temperatures, or using food coloring on your plant to obtain a purple hue. These methods do not work, and will affect the quality of the plant.


The first step to growing purple cannabis is having the right seeds. By getting seeds with a high level of anthocyanin, your plant will already have the genetic profile needed to produce a purple plant. The next step is ensuring you time your grow correctly. Winter or fall time are the ideal seasons because the chlorophyll of the plant breaks down much faster than in other seasons. Purple plants will need warm days and cooler nights (about a 30 degree difference is ideal). When your plant starts to flower, the temperature at night time should be around 50 degrees to achieve a purple pigment. Typically, it takes around 15 days before you will start to notice your plant turning purple.


Things to Keep in Mind

If you are considering growing purple cannabis, we recommend starting your grow indoors. Growing indoors can be easier to achieve the desired results because it is easier to control factors such as temperature. Other factors to keep in mind are soil and fertilizer. Having quality soil and fertilizer is imperative to the growth of your plant. In order to achieve purple buds, with a high THC content, be sure to follow the tips we have outlined in this article for optimal results!
