Red marijuana

In marijuana, red flowers are not that rare, but buds and leaves of this color are decidedly less common.

Red cannabis is a genetically selected plant and is born from the combination of three types of varieties: ruderalis, indica and sativa . Red Critical , in particular, is best known for its hybrid effects, which simultaneously offer great relief to the body and mind, and is known for its intoxicating aroma.

There are also some varieties with beautiful shades of pink, such as Predator Pink, or Pink Kush with reflections almost tending towards fuchsia. These are Indica-dominant hybrids with powerful effects on the body, known for their ability to counteract the sensation of pain , insomnia and loss of appetite.

Orange and yellow marijuana

Carotenoids produce the warm hues found in many vegetables, such as carrots, pumpkins, sweet potatoes, pumpkins and tomatoes. and, when present in cannabis, they can give the plant interesting yellow, gold and orange citrus shades . To obtain these colors more alkaline conditions are needed, i.e. a pH tending towards basic, and the shades mentioned above tend to emerge naturally at the end of the flowering phase.

Orange, as a rule, mainly affects the flowers and buds, as in the case of the Agent Orange, Orange Blossom or Tangerine Dream varieties. These are known for their fresh-cut citrus aromas and are considered excellent mood boosters.

Moving on, however, to the varieties tending towards yellow, these can take on this color following the presence of molecules such as beta-carotene, lycopene, lutein and zeaxanthin, among the over 750 carotenoids identified to date that the body can convert into vitamin A. Many flavonoids are also yellow and can affect the colors of cannabis.

Yellow varieties include Lemon Haze , Golden Lemon and Strawberry Banana. Known for their sweet, citrusy aromas and high THC content, they are said to stimulate a calm, positive mood and sharpen creativity and sensory awareness.

Green marijuana

Green is the predominant color of most flowering plants, including cannabis, thanks to the presence of chlorophyll . Plant tissues often have so much of it that their green color masks the presence of other pigments.

Blue marijuana

Blue-tinged cannabis flowers have a high anthocyanin content and are among the most visually beautiful.

All types of marijuana of this color descend from Blueberry (a term chosen to recall the blueberry fruit), selected in Amsterdam in the seventies. The most popular strains among these are Blue Haze, Blue Mystic and Blue Cheese.

These Indica-dominant strains are known for their stoned effects and are sought after for relaxation and relief from muscle spasms, pain or stress.

Indigo marijuana

There are some rare varieties that are such a dark indigo that they appear almost black. The origin of these genetics can be traced back to Vietnamese strains, such as Vietnamese Black . Other hybrid strains, such as Black Willy and Black Tuna, share both distinctive buds and ebony leaves.

Purple marijuana

Purple cannabis strains are probably the most popular, such as Granddaddy Purple, Purple Haze and Purple Urkle. These types of marijuana, unlike traditional green cannabis, tend to be fruitier, due to the high number of anthocyanins.

The Purple Orangutan (or Gorilla) has some of the strongest purple hues in the world. This predominantly indica hybrid produces lush, thick buds, covered in trichomes and purple hues.

Red Critical, the red marijuana par excellence

As we have seen, there are different varieties of cannabis, relating to color differences, each with specific characteristics and effects that make it unique compared to the others.

A clear example is red marijuana, a plant compound famous for its sedative effects , well represented by the red par excellence: the cannabis Red Critical .

This is, as we have already seen at the beginning, a plant specially selected through the crossing of different types of marijuana , that is, it was created from the union of three genera of cannabis: ruderalis, indica and sativa.

During maturation, the plants take on a purplish or reddish color with very dark tones, a phenomenon that mainly affects the buds and, in part, also the leaves. This dynamic manifests itself in approximately 4 out of 5 plants .

After harvesting and after being dried, the inflorescences take on an even darker shade, even turning towards purple , with blackish tones.

In addition, the influence of the genetic heritage of ruderalis which ensures that Red Critical cannabis has a flowering phase independent of the day-night cycle , remaining stable during all growth phases, a characteristic that makes it rightfully included in the list of autoflowering.

Another well-known and loved aspect of Red is its scent, one of the most typical factors and therefore useful for recognizing it from other similar varieties that try to imitate its olfactory impact. The smell of the Red Critical marijuana is absolutely inimitable, the hint of fruit combines perfectly with that of musk and its relaxing effects make it extremely difficult to confuse it with other types of cannabis for those who know this fragrance well.
