Auto GDP by Aurora Winds Botanical Seeds
Purple Urkle × Big Bud × Ruderalis
Auto GDP by Aurora Winds Botanical Seeds is an autoflowering indica cultivar designed to replicate the classic Granddaddy Purple experience in a compact, fast-cycling plant. It automatically transitions to flowering, making it appealing for growers seeking speed and reliability.
Appearance
This cultivar typically grows into a compact, bushy plant with closely spaced nodes. Its flowers often form dense, rounded clusters that can resemble golf balls, with some developing into spear-like shapes on the upper branches. Pigmentation can intensify in cooler temperatures, resulting in vibrant violet to deep amethyst hues on the bracts, contrasted by lime-green sugar leaves. A prominent layer of trichomes covers the flowers, giving them a frosted appearance, with resin heads often appearing cloudy to amber when mature.
The plant's pistils usually range from sunset orange to burnt copper. Ruderalis-indica autoflowers like Auto GDP commonly reach heights between 60-100 cm. The leaves are typically broad and dark, with distinct serration and a morphology characteristic of indica strains. Its structure is generally robust, capable of supporting dense flowers, though larger colas might benefit from light support.
Aroma & Flavor
The aroma of Auto GDP is characterized by a layered sweetness, featuring prominent notes of grape and berry, often compared to grape candy or Concord grapes. This fruity profile is complemented by earthy and resinous undertones, reminiscent of damp forest floor, wood, and musk. As the flowers cure, spicy and peppery notes may emerge, and a hint of pine can be detected, particularly when the buds are handled.
On the palate, Auto GDP delivers a prominent taste of grape, berry, and candy-like sweetness upon inhalation. The exhale introduces deeper flavors, including earthy cocoa, cedar, and pepper. When vaporized at moderate temperatures, fruit esters and brighter monoterpene notes become more apparent, while combustion tends to emphasize the earthier, hash-like qualities.
Effects
Auto GDP is generally described as producing a deeply relaxing and mood-brightening effect. It is known for inducing a sense of calm and tranquility, often leading to a tranquil euphoria. The cultivar aims to synchronize mind and body, providing physical relaxation without demanding significant mental effort. This profile makes it suitable for unwinding and quieting the mind.
Terpenes & Cannabinoids
The terpene profile of Auto GDP is commonly dominated by Myrcene, Caryophyllene, and Pinene. Minor terpenes such as Linalool and Humulene may also be present, contributing subtle floral and herbal notes. These compounds are associated with the strain's relaxing qualities and its characteristic grape and berry aroma.
THC levels in Auto GDP typically range from 18% to 22%. CBD content is generally less than 1%. The combination of these cannabinoids and terpenes contributes to the strain's overall effect profile, which is often favored for evening use due to its calming and sedative potential.
Growing
As an autoflowering cultivar, Auto GDP transitions to flowering based on plant age rather than changes in light cycles, a trait inherited from its ruderalis genetics. This feature allows it to complete its life cycle from seed to harvest within a single season, even under less-than-ideal light conditions. Ruderalis genetics also often impart cold tolerance and a rapid life cycle.
The plant tends to maintain a compact, bushy stature, making it suitable for smaller cultivation spaces. Its indica heritage contributes to dense, conical flower structures with high calyx-to-leaf ratios. While generally robust, the dense flowers may benefit from light support to prevent top-heaviness. The overall growing process is considered reliable and speedy, characteristic of modern autoflowering strains.
Origins & Lineage
Auto GDP by Aurora Winds Botanical Seeds is an autoflowering adaptation of the classic Granddaddy Purple (GDP). The original GDP is widely credited to breeder Ken Estes and is a cross between Purple Urkle and Big Bud, known for its purple coloration, grape-berry aroma, and tranquil effects.
To create Auto GDP, Aurora Winds Botanical Seeds stabilized GDP-like phenotypes with ruderalis genetics. This introduction of ruderalis allows the plant to flower automatically, independent of photoperiod. The breeding process typically focuses on preserving the flavor, color, and effects of GDP while ensuring reliable autoflowering traits and competitive potency.
