Lineage: Grandaddy Purple × Bruce Banner — two strains that rarely agree on anything. GDP pulls this cross toward the couch with its heavy grape-and-berry body, while Bruce Banner keeps pushing THC into that 20–25% range and adding a sharp diesel edge that cuts right through the fruit. The result smells like a citrus grove parked next to a gas station, which sounds odd until you're actually growing it and realize the contrast is what makes the jar interesting.

Blimburn built this as a feminized indica for both indoor and outdoor runs, and the 8–10 week flower time sits comfortably in that range without much variance if you keep conditions stable. Indoor growers pulling 400–500g/m² should plan canopy management early — the structure can get dense. Moderate difficulty means beginners will need a few runs under their belt before this one rewards them fully; intermediate growers who already have a trained eye for humidity control will get the most out of it.

Growing Grandaddy Purple x Bruce Banner

Grandaddy Purple x Bruce Banner is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 40-50% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.
