The shortest version: Blimburn Seeds's take on indica genetics, 20-25% THC, 8-10 weeks flowering, moderate grow.

Lineage: Grandaddy Purple × Bruce Banner, bred by Blimburn Seeds. GDP contributes the unmistakable grape-and-berry nose while Bruce Banner pushes THC into the 20–25% range — a combination that produces something heavier than either parent suggests on paper. The smell leans fruity upfront, then shifts into a citrus-diesel finish that catches growers off guard the first time they crack a jar.

Flowering wraps in 8–10 weeks, and indoor runs regularly hit 400–500 g/m² under reasonable light. The plant handles both indoor and outdoor environments without much complaint, though outdoor growers in shorter Canadian seasons should start seedlings early under supplemental light to protect that finishing window. Difficulty sits at moderate — topping and basic canopy management will get more out of her than neglect will. Best suited to growers who have a run or two behind them and want a high-THC indica-dominant strain that doesn't require boutique-level dialling to perform.
