Origin
Granddaddy Purple is a cross of Purple Urkle and Big Bud, bred by Ken Estes in the San Francisco Bay Area around 2003. Purple Urkle supplied the grape and berry and the color, Big Bud the dense, oversized flowers. That account is consistent across sources. It has been used widely as a breeding parent, and a long line of purple and grape strains descends from it. When people say a strain is "a purple", Granddaddy Purple is usually the standard they are measuring against.

Cultivation Notes
Granddaddy Purple is an easy grow and a small one, usually staying under 30 inches, which makes it a practical indoor plant. It finishes in about eight to eleven weeks and yields well for its size, around 19 ounces per square meter indoors, with standard resistance to mold and pests. It wants a warm room with good airflow, and cooler nights late in flowering bring out the purple. Grower and breeder figures.

About
Granddaddy Purple hits you with the nose first: crushed grape and dark berry, sweet and a little musky, with the deep purple color to match. It is the strain most people picture when they picture purple weed. Ken Estes bred it in California around 2003 from Purple Urkle and Big Bud, and it has been the reference point for the type ever since.
A grape-candy smell that loud can read as a light, fun strain. The color is doing something different, and it is worth knowing which before you commit an evening to it.
What to Expect
Granddaddy Purple is a short, pleasant lift that turns into a long night. The front end is a dreamy, slightly floaty head haze, euphoric and calm; within half an hour or so it gives way to a heavy, couch-locking body weight that most reviewers describe as the main event. Across roughly 4,000 aggregated reviews, deep relaxation and sleepiness dominate, along with hunger.
It is an evening strain in the fullest sense: it ends the evening. A modest amount is a comfortable, drifting wind-down; more moves fairly quickly to foggy and then to asleep. Dry mouth is the standout complaint, noticeably higher here than for most strains, with dry eyes behind it. It is a poor choice for daytime, for anything requiring follow-through or for anyone reading the color as a quality or strength signal.
Flavor and Aroma
Granddaddy Purple is grape and berry with a sweet, almost wine-like muskiness and a spicy edge underneath. The comparison people reach for is grape Kool-Aid or grape candy. The smoke is smooth and keeps the grape through the exhale, where the sweetness builds. Broken apart, the buds turn more pungent and earthy.
Terpenes Explained
Granddaddy Purple's measured panel leads with Linalool and Limonene, then Myrcene and Caryophyllene, with everything else minor. The grape and berry impression that defines the strain is not really any single terpene on the panel; it comes from compounds outside the standard nine.
The color is a separate thing from the smell and worth clearing up. The purple comes from anthocyanin pigments, which the plant produces more of when night temperatures drop late in flowering. It is a response to cold, not a marker of potency, terpene content or quality. A greener Granddaddy Purple grown warm can be just as strong as a deep violet one grown cold.
Cannabinoids and Potency
Granddaddy Purple THC runs from about 15 to 27 percent in our records, with a lab-measured sample near 15. That is a moderate range, and several older sources put the average around 20. CBD is a trace, with a little CBN in some samples, consistent with the sleepy reports.
The number is not the story here. The body effect is heavier than the potency figure predicts, so what you are really choosing is how much couch you will accept. The purple is cold weather, not strength; buy it for the sleep.
