Granddaddy Purple Strain

Granddaddy Purple, also known as GDP, is one of the most iconic purple cannabis strains in the cannabis scene. This Indica-dominant hybrid of Big Bud and Purple Urkle has been a favorite of medical and recreational marijuana users since the early 2000s. Its sweet fragrance and soothing effects make this strain an excellent choice for consumers looking to wind down after a long day.

Granddaddy Purple Strain History

More than twenty years ago, Ken Estes, a prominent marijuana activist and breeder, set out to develop a cultivar that might help with sleeplessness and pain. He had grown to like a strain known as Purple Urkle, but was frustrated by its lack of yield. To enhance its bud production, Ken crossed his cut of Purple Urkle with a high-yielding cultivar known as Big Bud. He dubbed the new strain “Granddaddy Purple” to underscore the striking violet hues of its leaves and buds.

Ken’s new strain gained much appeal among growers and users after it was released in 2003. This strain went on to win several awards since its debut, earning a reputation as one of the most potent, fragrant, and high-yielding purple cultivars on the market.

Granddaddy Purple Strain Info

According to Ken Estes, Granddaddy Purple is an Indica-dominant hybrid of Purple Urkle and Big Bud. This hybrid exemplifies the qualities of both parent strains, offering the large yield and robust growth of Big Bud, and the sweet flavor and snazzy coloration of Purple Urkle.

Big Bud, the parent of Granddaddy Purple, is believed to be a three-way hybrid of Northern Lights, Haze, and Afghani cannabis strains. Purple Urkle, the other parent of Granddaddy Purple, is a renowned strain with an unknown pedigree. Some growers claim this strain is a select phenotype of Mendo Purps; however, its true origin remains a mystery.

Granddaddy Purple Strain Review

Granddaddy Purple is known for its distinct grape and berry flavors. Its aroma is also delightfully sweet, with notes of ripe citrus and grape soda that become more pronounced as this strain matures.

As an Indica-dominant strain, this cultivar delivers a profoundly calming stone that soothes the body. This cultivar has a reputation for delivering couch-lock effects accompanied by mild euphoria or stress relief depending on the user’s tolerance level.

Although it is a member of the Indica family, this strain does offer some subtle cerebral effects. This can be attributed to its hefty THC level, which typically ranges from 16 percent to 24 percent on average. Its high THC content makes this strain well-suited to consumers looking for fast-acting relief from stress and tension in the body and mind.

Granddaddy Purple Strain Yield

Like its Big Bud parent, the Granddaddy Purple weed strain is known to produce a sizeable yield. Under optimal indoor conditions, this strain can yield up to 19 ounces per square meter. Outdoors, it can produce as much as 17 ounces per plant.

Growing Granddaddy Purple

Granddaddy Purple is a relatively easy strain to grow. Its plants tend to lean toward the shorter side and can become quite bushy when cultivated indoors. It will typically flower within 8 to 9 weeks when provided with the right growing conditions.

Although not particularly picky when it comes to feeding practices, Granddaddy Purple is partial to organic soil mediums that are rich in nutrients. Fertilizers that are high in nitrogen should be used during vegetative growth, and plenty of phosphorous and potassium should be provided to the plants during the flowering period.
