Self-cultivation of purple cannabis has become very popular because more and more gardeners are looking for varieties of exotic colors that produce buds that attract consumers’ eyes and attention. You might have questions about how to grow purple marijuana plants. Blimburn Seeds Bank will teach you how to grow and optimize your purple weed plants!
Why does the violet cannabis plant exist?
Purple cannabis is a type of cannabis that has deep purple buds and leaves. There are also some varieties of cannabis with purple buds and green leaves. There are other purple genetics that show their color during the flowering phase, specifically in the ripening stage. In pot plants, this type of coloration is determined by flavonoids called anthocyanin which are a group of around 400 water-soluble pigments that can appear red, blue, or purple depending on the pH. So, if the pH is near neutral, as it should be, cannabis strains with an abundance of this pigment will likely end up with purple buds at the end of flowering.
When there are low levels of chlorophyll in cannabis plants, anthocyanins are produced which are manifested in color in the flowers of weed plants during the last weeks of life. A trick widely used by breeders to stimulate the production of anthocyanins and reduce chlorophyll levels is the reduction of the hours of light in flowering, especially during the last 3 weeks. This causes the plants to highlight their purple colors. In those Cannabis plants that are not purple, the flowers and leaves take on more orange and gold colors. It should be made clear that all cannabis plants can change color during cultivation.
Variations in the colors of weed plants can be the result of several factors such as the genetics of the cannabis strain or environmental factors such as temperature decreases and diseases including mold that turns the buds brown, causing gardeners to lose their crops completely as these types of flowers cannot be consumed and are bad for users’ health.
What about the leaves?
In general, the leaves are green because they concentrate a large amount of chlorophyll which is the pigment that gives them that color. However, they can change color as they mature in flowering. When the hours of daylight decrease naturally outdoors or when the farmer decreases the hours in the indoor crop, they tend to turn purple. If the temperatures drop, the production of chlorophyll is inhibited, increasing the production of anthocyanins and promoting the Purple color. In turn, anthocyanins can change color, so there are cases in which they mutate from a blue color to violet. There are also other pigments that can vary their color, for example: Lycopene is red, Carotenoids are yellow, and Anthoxanthin is white.
You must be careful because there are healthy processes that allow the leaves to change color, but these are not the only ones. Excess water and overfeeding cause symptoms such as yellowing, followed by wilting. Yellowish leaves can indicate natural and healthy processes towards the end of the life cycle of the weed plant or that something is wrong, either in its diet, ventilation of the place, cultivation, high temperatures, over fertilization, or other factors.
Trichomes and pistils in purple cannabis plants
Trichomes are very important for every cannabis grower because they show which process the plant is in. The color change of the trichomes is a super important part of the whole process because it teaches us that harvest time is approaching. When the trichomes go from a transparent white to a cloudy color, it means that the plant is ready to be harvested. Despite that, gardeners who prefer buds with a more relaxing effect will begin to harvest when the trichomes turn dark brown.
The content of cannabinoids and the proportion they contain is determined by the color of the trichomes. When they are still clear it is because they are developing and have not reached maximum power. It is also necessary to say that a cloudy or milky trichome contains its maximum amount of THCA, whereas in an amber or brown trichome, THCA has been degraded to CBNA. CBNA decarboxylates into CBN which creates a less psychotropic high, meaning it relaxes you, as we said earlier.
The pistils are the female sexual organ of the plant. In most flowers, they are called stigmata. Their purpose is to catch the pollen of the males while it moves with the breeze. They start with a white color and as they mature, they change color until they turn brown. If you want to have a good harvest, we do not recommend that you follow the pattern of the pistils and their color. On the contrary, it is better that you carefully analyze the trichomes and their tones.
Is purple marijuana more potent?
First of all, we will say that a marijuana plant being purple does not mean that it is more powerful than non-violet weed. However, we cannot deny that purple cannabis has a lot of potential and concentrates high levels of anthocyanin, giving it great analgesic, anti-inflammatory, and neuroprotective values.
There are other factors that make growing purple marijuana attractive despite not being more potent. These factors may include how exotic it is to grow purple cannabis, both for its colors as well as for having a different experience in your garden.
Now that you know more about purple varieties, we will give you some tips so that you can grow the best purple cannabis in your garden, whether indoors, outdoors, or in a greenhouse.
Tips to grow the best purple marijuana
1 – Control and lower the temperature of the garden
Experienced gardeners comment that for some purple strains, fluctuations in daytime and nighttime temperatures can help bring out those violet hues, thus stimulating the cycle change from summer to fall.
For example, changing the temperature from 25 ° C during the day to around 20 ° C at night will help the buds begin to show their purple color. We recommend using this trick when the growth cycle is ending as the plant goes into flowering because it will allow you to notice the change in tonality from pre-flowering.
2- Focus the light directly on the plant
According to some indoor breeders, purple cannabis plants consume a lot of light, so they recommend putting the lighting indoors as directly as possible towards the plant to activate the anthocyanin molecules and stimulate the appearance of the violet color.
Be careful if you use HPS lighting because the heat can damage the buds and reduce the harvest due to excess heat. Farmers who use led lighting can ensure that the plants are close to their lighting panels without damaging the flowers.
in most cases, we suggest using ventilation systems such as fans, extractors, and air inlets to ensure that the plant receives a good dose of fresh air and also has excellent ventilation despite the proximity to the lighting.
3 – Well regulated PH
Advanced growers estimate that acidic conditions (<7) enhance red colorations; neutrals (7), violets; and alkaline (> 7), green-yellow. For your purple cannabis plants to better highlight their colors, you should use PH 7. These are general parameters that marijuana farmers use that can help you get that purple weed you want.
4 – Select purple-dominant cannabis seeds
When selecting your cannabis seeds, make sure they have purple genetics so that you can have a guaranteed violet harvest. Regardless of whether or not you apply the tricks we teach you here, if your plants are not genetically predisposed to turn purple, it is impossible for them to take on this tonality when you cultivate them.
Here, we share some of the Blimburn Seeds varieties with which you can harvest the best purple marijuana of your life that will surely make you smile!
Black Water Purple OG Cheese
This strain is the cross of three different varieties including Black Water OG, Purple OG Kush, and Cheese. These three strains are known for their medicinal properties, but they are also known for their exotic flavors and colors. When ripe, it takes on intense purple tones in the leaves closest to the buds as well as to the entire flower. As you can imagine, Black Water OG Cheese is a mostly indica variety, therefore its growth as a Christmas pine is assured. For this reason, we advise you to do some pruning and cleaning in the lower and middle branches to enhance the growth of the flowering buds. This plant is ready to be harvested after 8 – 10 weeks of flowering indoors and at the beginning or middle of October outdoors.
For crops that are full of purple buds from the second week of flowering, we advise lowering the temperatures of the indoor growing area or waiting for the end of summer for outdoor gardeners. You can harvest 400gr – 600gr / m2 indoors, while outdoors, it rewards you with 350gr / plant.
Not only do the purple buds make this plant an exotic strain, but also its flavor as it produces sweet berry tones, notes and fragrances of cheese, and a refreshing aftertaste of pine combined with wood and humid earth.
Tropicana Cookies Purple
First of all, we want to warn you that this strain is incredible because it comes from a cross between Purple Punch x Tropicana Cookies, two super varieties that give it a mostly Indica character and make its buds a purple that is intensified during the flowering of weed plants. If you are a lover of the hashish, Tropicana Cookies Purple will not only reward you with its incredible purple buds, but also with a delicious flavor of incense and hashish accompanied by sweet fruit notes. All of the above is enhanced with the high power of THC that ranges from 21% – 22%.
It is also necessary to highlight the heavy yields that it delivers. Outdoors, you can harvest 400gr – 550gr / plant, while gardeners who grow indoors will obtain 400gr – 600gr / m2 of resinous, purple, and tasty buds.

Blueberry Baddaz Og
Blueberry Baddaz Og is another strain that takes purple tones in its flowers as it matures. The color is a mixture between purple and reddish that gives it a unique, exotic image. This variety was born when the famous Blueberry x Og Kush were crossed. For this reason, it is mostly indica and surprises novice farmers because it is very easy to grow. The potency of this girl is super strong as she has THC levels ranging from 19% – 24% in her purple buds. It can be harvested after 7 – 9 weeks of flowering indoors and between late September and mid-October for outdoor farmers. We also tell you that this girl’s crops are heavy because outdoors, you can pick 600gr – 700gr/plant and 450gr/m2 indoors.
Now, to stimulate the purple color of the buds, we recommend lowering the temperature of the grow room a bit. Another trick that may work is to water the plant during the second or third week of flowering with a little ice water. The cold water can stimulate the production of purple flavonoids.
The flavors of this variety are berry with notes of wood and sandalwood. It has a sweet aroma that relaxes the palate as well. The effect that Blueberry Baddaz OG produces appears as slightly energetic and very cheerful, but as you smoke more, it gently relaxes you.
