Product Details
Genetics & Lineage
GDP THCA, short for Granddaddy Purple, was created in the early 2000s by breeder Ken Estes through crossing Big Bud with Purple Urkle. Big Bud contributes massive yields and dense bud structure, while Purple Urkle adds the signature grape flavor and deep purple coloration. The result became one of the most celebrated indica strains in California, winning multiple Cannabis Cup awards and defining the West Coast purple flower movement. This THCA version preserves the legendary genetics while delivering full psychoactive potency and the visual appeal of deep violet hues.
Terpene Profile
Myrcene dominates with earthy, musky notes and sweet grape undertones that deliver profound sedation and body-melting relaxation. Caryophyllene adds spicy, peppery accents with anti-inflammatory properties that enhance physical relief. Pinene contributes subtle pine notes that add complexity without overwhelming the sweet berry character. Together, these terpenes create the iconic GDP aroma: sweet grapes, fresh berries, earthy undertones, and a hint of spice.
Growing Process
GDP THCA is cultivated indoors under full-spectrum LED lighting in small batches with careful temperature control to encourage purple pigmentation. Each plant is hand-tended throughout its lifecycle and hand-trimmed after harvest to showcase the stunning purple coloration and preserve trichomes. Buds undergo cold-curing at 60°F for 14+ days to develop full grape-berry flavor and potency, then nitrogen-flushed packaging locks in freshness. Zero synthetic pesticides or plant growth regulators are used at any stage.
What to Expect
Effects onset within 5-10 minutes with a wave of cerebral calm followed quickly by heavy physical relaxation that spreads throughout the body. Within 20-30 minutes, expect profound sedation, reduced stress, and potential couch-lock that makes this ideal for bedtime or lazy evenings at home. Peak effects last 3-4 hours with substantial potency. This is a powerful indica best suited for evening use when you have no obligations. New users should start with a smaller dose and wait to assess tolerance before consuming more.
Storage & Handling
Store GDP THCA in a cool, dark space between 60-70°F with the bag sealed to preserve the purple coloration, terpenes, and potency. Properly stored, your flower maintains peak quality for 6-8 months.

Recommended Use For This Product
Roll Your Own — Grind to a medium consistency and roll in your preferred paper or wrap. This method delivers the full aroma and flavor of the terpene profile with each draw. Best for experienced users who enjoy the ritual of rolling and want maximum flavor expression.
Bowl or Bong — Pack loosely for better airflow and light the corner of the bowl for controlled hits. Water filtration in a bong cools the smoke and reduces harshness, making it ideal for larger hits. Onset is fast, typically within 2-5 minutes, with peak effects around 15-20 minutes.
Dry Herb Vaporizer (Recommended) — Set temperature between 350-400°F for the best balance of flavor and potency. Lower temps (350-370°F) emphasize terpene flavor and produce a smoother, more cerebral effect. Higher temps (380-400°F) extract more cannabinoids for a stronger body high. Vaporizing preserves more terpenes than combustion, is easier on the lungs, and delivers a cleaner, more nuanced experience overall.
Duration & Effects
0-5 minutes: Rapid onset after inhalation. Initial effects include a cerebral rush, heightened sensory awareness, and a shift in mood and headspace. The strain's unique terpene character is most noticeable during this phase.
5-20 minutes: Effects intensify and settle into the body. Depending on the strain, you may feel uplifted, creative, and social (sativa-leaning strains) or deeply relaxed with muscle tension dissolving (indica-leaning strains). Euphoria typically peaks during this window.
20-60 minutes: Steady plateau. The psychoactive high levels into a consistent, sustained experience. Body effects deepen — indica-dominant strains bring heavier physical relaxation while sativa-dominant strains maintain cerebral energy and creative flow.
1-3 hours: Gradual comedown. Effects slowly taper into a pleasant, mellow ease. Appetite typically increases. Some users experience mild drowsiness, especially with indica-dominant strains. The comedown from smoked or vaporized flower is generally smooth and comfortable.
