Some cannabis strains are especially known for acquiring beautiful colours, normally at the end of the bloom stage.
Unlike others, which develop yellow-brown colours when chlorophyll degrades, some genetics acquire purple, bluish, reddish and even black hues.
Despite colour is a genetic trait, it can also be subject to environmental factors like cold temperatures at the end of the flowering period. Low temperatures promote the production of anthocyanins, the family of vegetable pigments responsible for the colour of blueberries, blackberries, cherries, black grapes, eggplants, etc.
Proper flushing of nutrients at the end of bloom also allows the plant to show its most beautiful colours while improving the quality of the harvest.
Except in specific cases, these beautiful colors are only shown at the end of bloom, so plants remain green during growth and early stages of the flowering period.
Each seed produces a unique individual - phenotype - so it should be noted that it is possible to find purple plants and green plants among seeds from the same strain.
Sometimes, only leafs turn purple, while other times perhaps we only find purple pistils or buds. Of course, we can also find completely purple phenotypes, both leafs and buds.
In this category you'll find all the purple strains of our catalog, so you can enjoy beautiful and coloured crops in your garden.
