Grand Daddy Purp | Indica: Analytical Profile, Industrial Applications & Research Compliance
Informational Section: Overview & Scientific Context
Grand Daddy Purple (GDP) is a hemp-compliant indica cultivar known for its deep purple pigmentation, complex terpene expression, and stable cannabinoid profile.
Developed for industrial and research applications, GDP’s genetic consistency and resin density make it an ideal sample for analytical chemistry, extraction yield optimization, and terpene mapping under ISO/IEC 17025 laboratory conditions.
Originating from Purple Urkle and Big Bud lineages, Grand Daddy Purp is often used as a reference cultivar in studies examining anthocyanin concentration, cannabinoid expression, and VOC (volatile organic compound) production in hemp.
