Grandaddy Black: Dark, Resinous Buds Made with Indica Genetics

Grandaddy Black by Original Sensible Seeds is a cross between Grandaddy Purple and Black Domina – two Indica powerhouses resulting in a mainly-Indica hybrid that delivers incredibly heavy yields of dense, sticky cannabis flowers.

Fantastic Indoor Strain!

The bar for indoors growers has been set very high over the past few decades and Grandaddy Black dares to push this even higher, with her fantastic package of heavy bud production, fast flowering times, and her lovely display of beautiful color toward the end of flower. This can be boosted further by lowering the temperature of the grow tent at night during the last two weeks of the grow cycle. Indoor yields for this strain are up to 600g/m2 after a 65 day flower while outdoor plants can bring in as much as 800g/plant when harvesting mid-October. Here is some more information to help you grow this strain:

  • Medium height – Grandaddy Black grows to a final height of 90-140 cm.
  • Max EC of water – 1.4 in veg, up to 1.8 in flower.
  • Water pH: 5.8-6.0.
  • Recommended lighting: Veg: 450 W CFL, Flower: 1000 W HPS.
  • Recommended nutrients: General Hydroponics General Organics range.

Excellent for Pain Relief

Grandaddy Black has a beautiful visual appearance: her buds are dark, resinous, and covered in a blanket of trichomes which make her sticky to the touch. Not only does she have fantastic visual appeal, this Indica-dominant hybrid has an intense effect which initially soothes the mind but slowly makes its way to the extremities.
