Buy marijuana strains by its color

Pigments such as carotenoids and flavonoids influence the color of marijuana strains, also do certain external factors such as thermal amplitude, which is the difference between the coldest temperature of a period and the highest. The last one affects mainly purple plants.

Coloured marijuana has been growing all over the world for millennia, and during this time the different strains have been related to each other, giving rise to combinations that did not exist at first.

In our time, breeders began to discover these plants in their expeditions, often only a few specimens showed different colours, although after a selection and stabilization work, these pigmentations could be fixed so that almost all the descendant plants offered the same colours.

Marijuana seeds are sold as a collector's item and can only be germinated in those places and situations where this is legally permitted. Natural Experience declines all responsibility.

The colours of Cannabis what causes them?

More and more cannabis seed collectors are demanding strains with bright colours and a unique appearance. As a rule, people associate crops with the colour green, but the reality is that there are many varieties of seeds that can produce plants with specific colours.

The colours of Cannabis can make a seed strain much more attractive and a big seller. That is why seedbanks are rushing to come up with new strains with purple, reddish, orange, blue tones...

One of the reasons for the colours of Cannabis are phytochemicals, biological compounds present in plants that have the ability to reproduce colours in plant species. The following are some of the most common phytochemicals that can be found in seed strains.

Chlorophyll is the chemical element that most determines the colours of Cannabis. It is the pigment that is most present in indoor and outdoor crops, present in up to 70% and is responsible for the green colourations. This explains why green predominates in most crops.

Chlorophyll plays a fundamental role in the development of plants beyond determining their colour. Thus, this chemical element is essential for absorbing light and carrying out photosynthesis, the process by which the plant exchanges gases. 

Anthocyanins are a group of approximately 400 pigment molecules and can be found in flowers and fruits of various crops. Anthocyanins can modify the colours of Cannabis depending on the pH to which the crop is exposed and have the property to give purple or blue colour to crops.

The use of LED lighting devices can increase the chances of antitocins being present, as they can act as a method of defence against overexposure to sunlight. In other words, increased stress encourages the production of anti-tocins, which can also change the colour of an indoor or outdoor crop. In this sense, it is not advisable to overdo it with overexposure to light, as this can stress the crop too much and affect the crop's development. 

Carotenoids are also responsible for the colours of Cannabis. It is a molecule that is not only available in plants, but is also commonly found in other living organisms such as human beings. All crops synthesize carotenoids responsible for the red Cannabis colours, although these molecules are often masked by the high concentration of chlorophyll.

Other reasons that determine the colour of the strains

The photoperiod to which crops are exposed can also determine the colours of Cannabis, when indoor or outdoor crops begin to receive less exposure to light, the green produced by chlorophyll will fade, and certain strains may develop different colours.

Temperature is another relevant factor for the colour of the crops. Chlorophyll production will be inhibited when crops are exposed to low temperatures, which will cause the Cannabis to change colour. This is the reason why many seed varieties can result in blue or violet coloured plants in certain cases when exposed to low temperatures during flowering. 

The pH of the crop is also a factor that can influence the colours of Cannabis. For example, a pH level below 5.5 is likely to produce reddish colourations in indoor and outdoor crops. On the other hand, pH levels above 7.0 may produce more bluish tones.
