Today we have thousands of different genetics to choose from and we may also want to ask our favorite plant that in addition to high yield, power, flavor and smell, to cheer our sights with unusual colors, leaving behind the green tones to move to different shades gradually, while disappearing the green pigments of chlorophyll, will go from the usual color to purple and even red, or pink.
The origins of the purple genetics are not very clear, different stories are told, such as when Sam the Skunkman was in the 70's in California trying to shorten sativa landraces flowering, a phenotype emerged by mistake and ended up being purple. From there came Purple Haze #1, a strain that is a legend and is still grown today, especially by Sativa lovers. If you are interested in more information about this strain click here.
But let's get back to our business. Why do certain types of cannabis genetics have the ability to change color and the vast majority do not? Well, it has a relatively easy explanation, but we have to get into the field of molecular genetics. If you study the genetic code of cannabis, you will see that it contains a certain volume of flavonoids, here is the key, since these are water-soluble pigmentation molecules, called anthocyanins.
These pigment molecules are mainly found in fruits, but depending on the strain you can even find them distributed throughout the plant, from roots to leaves. Anthocyanins are responsible for color change of the plants for the protection against ultraviolet rays or to avoid predators attracted by the green of the plants.
When we grow a cannabis genetic with this characteristics we need also in most cases low temperatures to influence the plant colors at the end of the flowering. He have to advise that increasing the temperatures range to get cold nights and therefore more purple colors can serve to reduce, in a directly proportional way its yield, which we assume is not an interesting point to any grower.
The nutrients also affect the color of the plant, so with a lack of phosphorus or nitrogen the stems of the leaves will turn purple, just like the veins of the leaves with the lack of sulfur.
Keep in mind that this only serves certain genetics, and depending on the phenotype, it may not have been inherited. Said that, take in account that in the same package of seeds, some plants will change color and others will remain green as we are accustomed.
To taste a very good quality purple sativa we can offer to you Shaman from the Dutch Passion seedbank. This genetics comes from the crossing of a Purple #1 ,well known for being the first Purple seeds on the market, male and a first class Skunk female. This flowering plant of 7 to 8 weeks has a very high production and is designed for outdoor and especially greenhouse because it is incredibly resistant to mites as well as mold and rotten buds.
If you prefer to try an autoflowering, Fast Buds' LSD 25 looks spectacular. This genetics coming directly from the United States has a 20% THC, which as we already know, is a lot for an autoflowering specimen. It is very compact and its production is up to a quarter of a kilo outdoors and half a kilo per square meter indoors ready to harvest between 56 and 63 days. Its flavor is spicy, with diesel notes and its high is quite psychoactive.
