Description
This cross is a velvet fist. White Truffle brings the glue — Gorilla Glue grit and Peanut Butter breath — and GDP brings the purple fanfare. the plants stand medium, squat to four feet, shoulders squared, internodes polite but packed. branches hold weight like old men hold grudges; colas stack dense and spade-shaped, each bud a sugar-coated knuckle.
🌱 Genetics: White Truffle × Grand Daddy Purple
⏱️ Flowering: 8-9 weeks
🟣 Purple Expression: Low to Medium
📊 THC: Medium to High
🎯 Difficulty: Moderate
🌱 Growing Behaviour: steady, honest. responds well to moderate feeds, enjoys slightly cooler nights to coax color, hates humidity in the final weeks — keep airflow and vigilance. indoor yields sit in the 400–500 g/m² range when treated kindly; outdoors, well-tended plants can flirt with 400–600 g. trim-to-bud ratio is generous; manicuring is quick and satisfying.
🌳 Flowering:here runs like a loaded clock — 8–9 weeks to finish, with the mid-season stretch giving way to heavy colas that swell like bruised fruit. By week 6 the trichomes riot, a sugar storm coating every calyx. Drop the temps late if you want the purples to scream. Keep air moving, keep humidity low, or the density will betray you.
Phenotype Variations: Expect 3-4 distinct phenotypes ranging from GDP-leaning purple expressions to White Truffle-influenced trichome monsters.
🫀 Breeder: Grand Daddy Purple
🏁 Country: USA 🇺🇸
🎱 Line: A Plum Pandemonium
💥 True, brutally honest findings: Phenotypes break into 3–4 tribes. You’ll meet the GDP purples—short, bushy, grape-candy reek. Then the Truffle fiends—thick resin armor, earthy-nut funk, maybe less purple but oozing frost. Hybrids that marry both into purple-frost monsters, and the greener oddballs with wild terp twists. The keepers hide in how they smell and how sticky your scissors get.
🥦 Yield rewards patience: run 400–500g/m² indoors, 400–600g a plant outdoors if you give them sun and room. The purple GDP types finish a hair earlier, the Truffle frost-beasts pack on late. Resin is the real jackpot—sticky enough that hash bags and presses sing when you feed them these flowers. Every phenotype pays, but some will make you swear allegiance.
😮💨Concentrates: gold or gasoline, depending on which child you coaxed into existing. rosin that smells like a cheap jukebox and tastes like grape cola with a diesel afterburn; hash that melts into stories. some phenos make trophy-grade extracts — keep them.
How deep can you stare into purple before it stares back?

🟣 Color: reads like a funeral for light. deep purple to near-black, often dusted with diamond frost. cool nights push the pigment further — the plants bruise into majesty. about seventy percent dress in purple robes; the others wear green with a sugar crust so thick they look glazed. trichome production is obscene: under a loupe the buds are moonscapes, micro-ice catching every angle.
🫦 Aroma & terpene circus: a civilized riot. GDP’s grape candy rolls in first, laced with White Truffle’s nutty, earthy backbone and a skunky whisper that smells like a mechanic in a fruit shop. imagine grape syrup poured over warm peanut brittle with a diesel aftertaste — myrcene’s pull, limonene’s rare smile, caryophyllene’s peppered handshake. the nose deepens with cure: the peanut notes become dessert-slow, the grape waxes regal.
🤯 Effect: lean into evening but not into sedation’s grave. you get a polite head-raise — a soft lens that sharpens thought just enough — then the body melts into a slow, useful calm. pain eases like traffic at midnight; sleep follows, not forced but invited. THC often rides high (low twenties into mid-twenties), potency that carries weight without becoming cruel.
