Seb's take
Grandaddy Purple and Black Domina, two indica powerhouses, combine in Grandaddy Black for heavy yields of dense, sticky flowers. Sweet, fruity and earthy on the nose; the high is happy before it turns relaxed and properly sleepy at 23% THC — the sitting-down sort, and no mistake.
Where it comes from
Original Sensible Seeds paired two indica powerhouses for this one: Grandaddy Purple and Black Domina. The Grandaddy side brings the purple colour and sweet fruit; Black Domina, a famously dark and resinous creation, brings density and depth. At 95/5 there is barely a trace of sativa in it. The result, by the record's account, is heavy yields of dense, sticky flower — an indica bred from indica, with little diluting the lineage.
Nose & flavour
Sweet and fruity up top, with an earthy base underneath — the Grandaddy parent's dessert character grounded by Black Domina's darker, heavier profile. A dense, resinous smoke, and one that carries the sweetness the purple lines are known for without turning cloying.
The high
Happy to begin, a brief brightness, before the near-pure indica takes hold and turns things relaxed and then properly sleepy. At 23% THC and 95% indica there is only ever one destination here — the sitting-down sort, and no mistake. An evening plant, best kept for when nothing further is required of you.
Growing it
Feminised, medium at 90 to 140cm. Flowering runs 60 to 65 days, with heavy yields around 600 g/m² of the dense, sticky flower the record promises. THC sits at 23%. A generous, well-behaved grow — the resin will test your scissors, so keep them clean, but the plant itself asks little beyond that.
