What is the Double OG Kush strain?
Double OG Kush is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and these are our own genetics bred in Quebec.
Double OG Kush Autoflower is QCS’s take on a classic: the fuel-and-citrus Kush experience in a plant that finishes fast and needs no light schedule. We bred it from Big Bud and SFV OG Kush and crossed it with Ruderalis. It is feminized, compact and aimed at tents, closets and balconies.
SFV OG is generally described as a California OG Kush cut from the San Fernando Valley, known for fuel, lemon and pine. Big Bud is an old, productive indica often credited with heavy, chunky flowers. Together they point to a plant that is both flavourful and generous. Many seed companies sell something called OG Kush or Double OG, and their crosses differ, so the numbers here are for the QCS version only.
Is Double OG Kush indica or sativa?
QCS lists Double OG Kush as an indica autoflower and does not give a percentage split, so we will not make one up. Both named parents are generally treated as indica-leaning, and the product page describes a compact, forgiving plant, which fits.
If you are wondering what the indica label tends to mean for the feel of a strain, our guide to what indica does to you is a good starting point. Keep in mind that the effect still depends on the full chemical profile and on you.
Smell and flavour: citrus, skunk, diesel and floral
The QCS taste profile is citrus, skunk, diesel and floral, and the description adds OG fuel on top of the citrus and skunk. That is the signature of the OG family: a sharp, gassy nose with a bright lemony lift and a floral finish.
Growers commonly report that OG-type plants turn loud in late flowering, so plan odour control if you grow in a small space. A careful dry and a few weeks of curing usually bring out the lemon and fuel more clearly than a fast dry.
Double OG Kush effects
QCS describes an effect that starts uplifting and settles into relaxation. Consumers describing OG Kush-style flower often report a bright, happy opening followed by a heavier, calmer body feel, and an indica-leaning autoflower tends to follow the same arc. Many people like it in the late afternoon or evening.
The product page specifically advises starting small, because the potency is real. Effects vary with dose, tolerance and setting, and dry mouth and dry eyes are commonly reported with high-THC flower. Start low and go slow.
How strong is Double OG Kush? THC content
QCS lists Double OG Kush at 20 to 24% THC. That is a solid, mid-to-upper range, stronger than light flower but below the extremes in our THC over 25% seeds category. The product page does not list a CBD figure.
Where you land in that range depends on light, feeding, drying and curing. A well-run grow with a patient cure gives you the best chance of reaching the upper end.
Growing Double OG Kush: flowering time and yield
Being an autoflower, Double OG Kush needs no change in light hours. Indoors it finishes in 55 to 65 days of flowering, which QCS puts at about 10 to 12 weeks from seed, with a yield of 300 to 500 g/m². The page gives no outdoor per-plant yield, so we do not show an outdoor chart, but it does say a May start finishes in late July or August.
Growing tips
QCS calls it a compact, forgiving plant that tolerates temperature swings, which is why it works outdoors as well as in a tent. The dense buds benefit from good airflow in the final weeks, so keep a fan running and avoid overcrowding. Sow directly in the final pot, train gently and avoid heavy pruning.
Harvest by trichomes, not by calendar. Our autoflower seeds guide covers the basics for first-timers.
