Purple Dank. Granddaddy Purps. Grape Ape. Purple Urkle. Pur, you get the point. Whatever it is you call your pretty purple pot (say that 5 times fast), we have the answer as to why it is actually purple. Just like blueberries are blue and for the same reason blood oranges are so red, your dank can actually turn purple due to an occurrence called anthocyanin accumulation.
Yes, we looked at that word for five minutes to figure out how to pronounce it, too. Anthocyanin accumulation is indeed the reason for the color change in your bud. First and foremost, for each marijuana plant to produce anthocyanin pigments, it needs to have the proper genetic potential, and certain strains of cannabis just don’t have that.
Question: I heard all I would have to do is grow my marijuana plant outside, then it will turn purple.
Answer: Firstly, don’t disclose that you’re growing your own marijuana to anyone else. Secondly, this is somewhat true. Let us explain.
Many different strains of marijuana can absolutely turn purple due to their exposure of cold temperatures when being grown outside; here is the breakdown:
The coloring effect depends on the genotype of the plant and the growth timeline. You won’t begin to see the coloring change until the last few weeks of flowering. The key to growing beautiful purple marijuana is the time of year; the fall months are of the utmost importance as it’s just typically colder outside. Another fancy word, chlorophyll, comes into play during the final stages of growth and the lack of this guy allows the purple color of the plant to intensify. With the help of the coldness of the night, the ‘OK’ is given to slow production of chlorophyll, it then breaks down from the plant structure, one thing leads to another and anthocyanins increase in production and voila. The end result is vivid blue, red (in some strains, even gold) and of course magnificent PURPLE hues. Thus, dat purple dank.
Question: Can’t I just add food coloring to my water when watering my plant?
Answer: Please stop.
Not only will food coloring do nothing to the taste or smoke of your weed, but we highly recommend not participating in such antics. Ever. Color changes in marijuana plants happen naturally. Some growers who try to turn their marijuana different colors manually have found that depriving their plants of oxygen (or any other natural gasses for that matter), just to get purple weed isn’t the greatest of ideas.
Conclusion? Leave it to the pros, don’t stick your bud in the freezer and don’t even THINK about purchasing food dye.
