Best Purple Strains of Weed

Purple strains

The color purple is the most dynamic in the rainbow and is often associated with power, creativity, mystery, and magic. Purple strains boast a supernatural vibe of psychedelic hues that are pleasing to the eye.

Crops cultivated from purple marijuana strain seeds are typically indica dominant. The effects associated with these cultivars tend to be relaxing and sedating. Modern growing techniques have allowed sativa genetics to join the purple craze in the cannabis world.

The pigmentation of purple weed strains doesn’t affect their cannabinoid quantity or flavor profile. Anthocyanins are predominantly responsible for the violet color in cannabis, and genetics contribute to their effects and flavors.

Why some weed is purple

Before cross-breeding seeds hit the cannabis cultivation scene, growers were only spoiled with purple strains if growing environments allowed it. Cold temperatures activated anthocyanin molecules in plants that made way for purple tinctures to appear visibly.

Anthocyanins are water-soluble color particles found in plants that give them their color. Cannabis crops mostly receive their violet inheritance because of their genetic footprint; anthocyanin content is only a contributor alongside cold temperatures.

For example, some purple weed strains, like Purple Starkiller feminized, are produced from the genetics of two superior purple cultivars: Purple Kush x Starkiller. This lineage largely contributes to the color profile of this weed.

Apart from the genetic contribution and availability of anthocyanins, neutralized pH levels also affect the visibility of violet in cannabis crops. Some herbs are entirely purple from stem to cola, while others only present it in their buds and foliage.

Purple strains of weed show off their color on these parts of the plant:

  • Pistils: The tiny hairs remain purple after curing.
  • Calyxes: Resin glands and buds change to a strong violet color.
  • Foliage: Certain leaves are solidly purple and others are only at the base, tip, or edges.
  • Trichomes: Purple pigments appear on the ends of trichomes.

Beware of purple strains myths

Every grower wants to experiment, but there are many incorrect facts surrounding purple weed across the internet. Here are five myths about these cultivars:

  1. Don’t deprive your weed plants of oxygen; it only stunts their growth. 
  1. Don’t deprive crops of carbon dioxide; nutrients lost lead to an unhealthy plant.
  1. Don’t overload them with nitrogen; too many nutes can kill your crops.
  1. Don’t alter their light cycle; no sunlight, no big yield.
  2. Don’t adjust water amounts; changing cycles has negative effects on their life cycle.
