Grand Double Purple
Granddaddy Purple × Purple Punch
Grand Double Purple is a boutique indica cultivar bred to enhance the classic Granddaddy Purple experience. It typically combines Granddaddy Purple with another purple-hued parent, aiming to intensify its color, grape-like aromas, and deeply relaxing effects. Expect dense, trichome-rich buds with striking violet to near-black hues.
Appearance
Grand Double Purple plants are characterized by broad, dark green leaves that can deepen to plum or black shades during the late flowering stage. The plants maintain a stout, bushy structure with tight to medium internode spacing, making them responsive to training techniques. Buds are typically dense and rounded or club-shaped, often featuring a high calyx-to-leaf ratio that simplifies trimming. Mature flowers are heavily frosted with trichomes, resembling powdered sugar, and are contrasted by fiery orange pistils.
Aroma & Flavor
The aroma of Grand Double Purple is dominated by grape and berry notes, often compared to grape soda or jam. Expressions influenced by Purple Punch may introduce confectionary sweetness, reminiscent of baked blueberry pie or powdered sugar, with subtle vanilla undertones. Secondary aromas include earthy musk and soft floral notes, frequently linked to myrcene and linalool. Some phenotypes might also present a faint creamy citrus or spicy OG-like scent.
Flavors mirror the aroma, with prominent grape, blueberry, and blackcurrant notes. The exhale often reveals a creamy, pastry-like finish with hints of vanilla or marshmallow sweetness, balanced by underlying earthy and spicy undertones. When vaporized, fruit flavors tend to be cleaner, while combustion can bring forward peppery notes from caryophyllene and a nutty finish.
Effects
Consumers often report a combination of uplifting mood elevation and profound physical relaxation, characteristic of its Granddaddy Purple heritage. The initial experience can be mentally buoyant and content, gradually transitioning into a deep unwinding of bodily tension. At moderate doses, a cozy calm is prevalent, while higher doses can lead to significant sedation and heaviness. Effects typically begin within minutes and can last for several hours.
Terpenes & Cannabinoids
Grand Double Purple generally exhibits THC levels ranging from 17-23%, with some phenotypes potentially testing higher. CBD content is typically less than 1%. Minor cannabinoids like CBG may be present in small amounts. The terpene profile is frequently dominated by myrcene, contributing to ripe fruit aromas and potentially sedative effects. Beta-caryophyllene adds peppery notes and may offer anti-inflammatory properties, while linalool provides floral, lavender-like scents often associated with calming effects. Pinene can add a crisp, forest-like edge.
Origins & Lineage
Grand Double Purple is a cultivar name used by various craft breeders to describe crosses that intensify the Granddaddy Purple (GDP) experience. The backbone of this strain is the legendary West Coast indica, Granddaddy Purple. Common pairings include Purple Punch (itself a cross of Larry OG x Granddaddy Purple) or other elite purple varietals. These crosses aim to amplify color, grape-forward terpenes, and sedative indica characteristics. Some variants may carry a subtle OG influence from Larry OG.
Growing
Grand Double Purple typically displays indica-dominant morphology, characterized by medium vigor and a stout, bushy frame. Indoor flowering times generally range from 8 to 9 weeks, with some phenos finishing between 56-63 days and others preferring up to 70 days. The plants respond well to training techniques like topping. Achieving optimal color development often requires cooler temperatures during the late flowering stage.
