About Granddaddy Black
Genetics & strain profile
Granddaddy Black is a feminized, indica-dominant strain that combines Grandaddy Purple and Black Domina. It has 22% THC and 0.5% CBD, and the page describes it as easy to grow. It is listed under our October harvest category, so it is a plant for outdoor growers who can wait for the autumn. It has no reviews yet, so everything here comes from the breeder’s description and not from customer grows, and we will not claim results beyond that. A single THC figure is a guide and not a promise, since the final level depends on the plant and on how it is grown. Easy to grow still means paying attention to watering and airflow, especially on a first grow. Our seeds are guaranteed, so if a seed does not come up, contact us.
How Granddaddy Black grows
This is a photoperiod strain, so it flowers when you move to 12/12 indoors or as the days shorten outdoors. It flowers in 8 to 10 weeks and gives up to 450 g/m² indoors, and the page describes the plants as resilient. Outdoors, expect to harvest around October with up to 600 g per plant, depending on growing conditions. Treat the top of both figures as best cases. In Quebec and Ontario that means starting indoors in April, planting out after the last frost and using a cover or greenhouse for the last weeks of autumn rain. An indica-dominant plant makes dense flowers that hold moisture, so thin the inside of the plant, keep air moving and harvest on a dry day. Resilient does not mean immune, so check the undersides of the leaves regularly. Check your local rules before you plant.
Taste, aroma and effect
Sweet and fruity, with earthy undertones and hints of citrus and skunk. The effect is described as deeply relaxing. At 22% THC it is strong, so newer consumers should start with a small amount and wait before taking more, and effects vary from person to person. The skunk note means the smell carries, so plan for odour control indoors. Reviews are the best guide to how a strain behaves in real grow rooms, so check back as customers add theirs.
