Grandaddy Black Feminized Seeds

Grandaddy Black Feminized Seeds by Captain Seeds - Indica-dominant, grape-scented strain. Heavy body effect with sedative finish. Suited to intermediate growers.

  • Grape-forward aroma
  • Heavy night-time relief
  • Reliable resin production

Grandaddy Black blends grape-scented Granddaddy Purple traits with darker resin and structure from Black Domina. You will get dense, resinous buds with a grape and dark berry profile and an earthy spice finish. Expect 8 to 10 weeks of flowering and medium-high yields when you control stretch and feed steadily. Train early with topping and LST, maintain stable pH and EC, and keep late-flower humidity low to avoid rot. Use slow drying and a careful cure to bring out the terpene profile and smooth harshness.
