Aromatic chemistry
Yes — Bruce Banner pushes the THC higher than GDP alone. Same sweet-grape aroma, more body weight and more cerebral start.
Granddaddy Bruce is a hybrid — a cross that pulls from both sides of the family tree. The lineage is Granddaddy Purple × Bruce Banner. The balance leans on phenotype and the day-of harvest.
Granddaddy Bruce hits sweet grape up front, berry through the middle, and earth on the exhale. The smell out of the jar reads the same way — distinctive once you've had it once or twice.
Granddaddy Bruce tests in the 22–28% THC range, which puts it on the higher end of the shelf. Customers with a built tolerance handle it fine; lower-tolerance customers should go a half-dose or less the first time.
Granddaddy Bruce reads as an evening strain — body-heavy enough that customers commonly reach for it after dinner or at the end of the day, not before they need to be productive.
