Granddaddy Purple Weed Strain Review

The Granddaddy Purple weed strain, also known as Granddaddy Purps or GDP Marijuana strain, is a potent Indica dominant variety. It is a cross between the Purple Urkle and Big Bud strains bred by Ken Estes in 2003. Due to its robust effects and beautiful appearance, it is famous on the West Coast and the U.S.

It has a high THC level ranging from 20%-27%, 1% CBD content, and an Indica to Sativa ratio of 80:20. As a result, it has an instant, long-lasting and heavy-hitting high, which rushes into the head, slowly spreading to the entire body. 

What follows is cerebral and euphoric bliss, which elevates your moods, making you happy. The relaxation effects will induce laziness, putting you to couch-lock. In the long run, you will succumb to deep and profound sleep.

Granddaddy Purps Cannabis strain has a lovely and mouth-watering aroma and flavour. Upon breaking, the buds emit a sweet and citrus smell with grape and earthy tones. Similarly, the taste is exceptional, with sweet, berries, and grape notes.

With dark purple, large and dense buds, GDP is naturally a beautiful and eye-catching strain. The buds are blended in bright green leaves, which sometimes have vibrant purple hues. The buds are also covered in yellow, orange pistils and frosty thick crystalline trichomes.

According to most growers and consumers, the Granddaddy Purple strain is almost identical to the famous Grape Ape strain. The novice will easily confuse them since they have nearly the same effects, appearance, aroma and even flavour.
