Have you ever wondered why some cannabis plants are black in color? You might have come across such strains on the street or in stores. You might even be a grower yourself who suddenly noticed a change in color of your once vibrant green plant that has turned dark. You might be wondering why this happens and what it means. Don’t panic whenever you encounter this scenario; it is perfectly normal. Although this cannabis state is comparatively rare, it is a fact that black cannabis strains actually exist. It is however noteworthy that certain conditions cause the black, purple and blue coloring of some cannabis strains.
One most important factor in color changes in plants is a climatic condition. Marijuana plants that are cultivated in Mediterranean, warm climates have a propensity of being bright green in color, but cannabis plants that are cultivated in cool climates tend to produce compounds that turn them purple.
The compound responsible for this change in color is known as anthocyanins, and it acts as innate antifreeze of the herb. The antifreeze enables the plant to retain water that might escape the leaves as it develops into ice crystals between the leaf cells. Therefore, the cooler the climate, the more the anthocyanin that is going to be produced.
Anthocyanin has also been proposed by some researchers as a form of sunscreen for cannabis, protecting it leaves from certain dilution of light and enables it to absorb other types of light. One may then be wondering where the black strains come from if anthocyanin only explains why cannabis is purple. Well, the same anthocyanin found in plants such as black currants, black or blue tomatoes, black rice, etc. is the same found in cannabis. Therefore, the more the anthocyanins in a plant, the deeper its color.
This basis of the black color variant in cannabis is explained by the theory that this strain possesses a recessive phenotype which enables it to convert glucose to anthocyanin effectively. Hybrids from black strains can produce a range of colors from red to purple and at times, white. Therefore, the inheritance of a recessive gene from parent plant is an important precondition for cannabis offspring to remain black.
In addition to the effect of genetic and climatic factors on the coloration of cannabis plants, pH level also plays an important role. All cannabis plants naturally like a slightly acidic soil for their optimum growth. More interesting is the fact that increasing the pH can lead to a greater amount of reddish colors. The more neutral the soil pH, the more blue and purple coloration will be expressed. Isn’t it interesting that one could even create a rainbow of buds by slightly altering the soil pH level?
To conclude, black cannabis is still rare and largely untapped as a selling point in the marketing of cannabis as a whole. This unexplored unique selling point is as result of cannabis being banned in several countries across the world. However, there is a growing market for this variety of cannabis since countries legalizing cannabis are increasing daily.
Cannabis is a plant with an enormous potential as a health supplement and healing aid, and of all its varieties, no variety possesses higher potential than black cannabis.
