Grandmommy Purple has a long history spanning more than 25 years, albeit one marked by ups and downs and even some tragedy. It is believed that the original version of this 70% Indica was lost in 1998. However, the breeder insists that they have recreated the coveted pre-98 genetics in all its glory.


This Indica-dominant hybrid is a cross between a premium OG Kush phenotype and a landrace Afghani. With a family tree like this, you can be sure of distinct Afghan Kush characteristics that are present in many modern varieties but often diluted too much.

Flowering Time

A fast-flowering cultivar, Grandmommy Purple normally needs no more than 56-63 days from the moment you induce flowering. Outdoors, the buds will be ready for harvest around the first or second week of October (assuming your climate allows you to grow photoperiod strains in the first place, of course).


In experienced hands, Grandmommy Purple is extremely high-yielding, producing harvests of up to 550-600g/m² (1.8-2oz/ft²) indoors. If you’re lucky enough to live in a warm or temperate climate that allows outdoor cultivation, the yields may even reach up to 1kg (2.2lb) per plant.


Expect head-to-toe relaxation and drowsy euphoria as the world and its many problems recede, leaving you with a dreamy buzz for hours. Let the beehive of life hum around you while you remain perfectly motionless, serene, and happy.

Medical Properties

Any physical or mental ailment that cannabis is supposed to cure can be alleviated with this ultimate medical strain. Among other things, patients use Grandmommy Purple for pain, insomnia, and stress, as well as an appetite stimulant.

THC and CBD Levels

While the pre-98 Grandmommy Purple wasn’t particularly potent at 17% THC, all attempts to reboot this genetic, including this one, were accompanied by efforts to raise THC content. In Grandmommy Purple by Barney’s Farm, the THC level can reach an astounding 29%.

Smell and Taste

One of the strain’s highlights, her terpene profile is a blast from the past for those old-timers who came to love the flavor of Afghani hash. Subtly sweet, earthy, and spicy aromas usher in a taste of hashish sweetness with notes of chocolate and mocha.

Grow Tips

The Afghani heritage of Grandmommy Purple has imbued this plant with a compact bush structure in veg and only a modest stretch in flower. This makes the strain invaluable for those who grow in confined spaces. However, you can see this weed grow to gigantic proportions as well if you plant Grandmommy Purple outdoors.

  • Expect an indoor height of 100-120cm (3.5-5ft) and an outdoor height of 150-200cm (5-7ft)
  • Plants are big and dense but have mold-resistant buds
  • Your work will be rewarded by huge bag appeal thanks to the strain’s resinous multicolored nuggets

Through the process of feminization, the breeder made Grandmommy Purple seeds grow into female plants only, freeing you from the nuisance of sexing and the risk of having pollen in your garden. Though feminized, these seeds still come at an affordable price.
