Grape Skunk Cannabis Seeds Feminized

Genetics & strain profile

Grape Skunk is one of our QCS Originals and one of the most-reviewed strains in the catalogue: 31 reviews averaging 4.7 out of 5 and ten public grow diaries. It is a 60% indica, 40% sativa hybrid with 17 to 20% THC, easy to grow, in our beginner-friendly selection and in our Featured Strains. The reviews are about size, colour and ease. A SCROG grower’s plant finished 11 feet tall and 10 feet wide with three dozen 18-inch colas, pistils pink then buds deep purple; a southwestern Ontario grower had a plant 7 feet tall and 7 feet wide in a 10-gallon pot on his deck; another has grown it three years running. The kief, one reviewer notes, comes out purple, and so does the hash. The honest note, and it comes up twice: at 17 to 20% THC it is not the strongest strain — “the strength is average, but also depends on how you grow” — and one grower of a freebie felt little effect. If you want potency first, look at our 25%-plus strains; if you want a big, beautiful, forgiving plant, this is it.

How Grape Skunk grows

It is a vigorous plant — a “green machine during veg” — that grows fast and big outdoors, reaching 7 feet or more in a large pot and far more in the ground, so top it early and net or stake it. It handles a high EC, as one reviewer notes, so it is hard to over-feed; the buds are not too leafy and are easy to trim. Indoors it flowers in 7 to 9 weeks with up to 450 g/m²; outdoors expect to harvest around late September to early October with up to 550 g per plant in optimal conditions, which makes it a solid choice for Canada’s short season. A public diary records a plant over 7 feet tall and 875 g wet that came through heavy July rain and humidity with no mould, and a 2025 Ontario grower reports no insects, powdery mildew or mould in a difficult year. Cool nights late in flower bring out the purple and pink.

Taste, aroma and effect

Berry, skunk, citrus and grape — both fruity and pungent, with a “very sweet grape smell” on the plant and a tasty, smooth smoke after cure. The high is balanced and relaxing, a “nice relaxing high with excellent taste”, suited to an evening without being a knockout. For the strain’s Skunk relatives bred here, see Quebec Super Skunk and Biscotti Skunk; for a purple strain with more punch, Purple Kush; to buy it by the hundred, bulk seeds.
