SSKUSH Strain Review: THC, Effects, Flowering Time & Yield

SSKUSH is an original QCS strain: a feminized Sour Diesel × OG Kush balanced hybrid with 26% THC, about 60 days of flowering and 475 to 550 g/m² indoors. This review pulls together our specs, the nine customer reviews on our site (the good and the less good) and what growers commonly report about its famous parents.

SSKUSH strain at a glance

What is the SSKUSH strain?

SSKUSH is an original QCS strain: Quebec Cannabis Seeds is its original breeder, and these are our own genetics, bred in Quebec since 2015 by a grower with more than 35 years of experience.

SSKUSH (pronounced "S-S-Kush") is one of our own QCS crosses, built from two heavyweights of the diesel and OG world: Sour Diesel and OG Kush. Sour Diesel is famous for its sharp, gassy aroma and energetic reputation, while OG Kush is known for its pungent, earthy fuel and heavy resin. Crossing them is a long-standing idea among breeders, and the QCS version is a balanced hybrid that stays medium in height and finishes in about 60 days indoors.

Both parents are used by many seed companies in their own crosses, so published numbers for similarly named strains can differ. The figures in this review are for the QCS version only.

Is SSKUSH indica or sativa?

QCS calls SSKUSH a balanced hybrid, with no exact percentage published. That fits the cross: Sour Diesel is generally considered sativa-leaning and OG Kush indica-leaning to balanced, so the offspring sits in the middle. In the garden, expect medium height in veg followed by a stretch in early flower, then dense, resinous flowers. If you are curious about the heavier indica side of the spectrum, our guide on what indica does to you explains the usual feel.

Smell and flavour: diesel, fuel and sour fruit

The QCS profile is diesel, described as fuel with fruity and sour notes, and the aroma adds citrus and earth. Growers commonly describe Sour Diesel and OG Kush crosses as loud and gassy, so expect a smell that gets strong from the third or fourth week of flowering. Customers reported some different notes: one grower said his plants were smelling like grapefruit, and another said the flavour was special, with a surprising wet-cotton character. That is a reminder that terpene expression varies between plants and cures.

As with any gassy cultivar, a good dry and a slow cure make a big difference to the flavour, and odour control is a must indoors.

SSKUSH effects

QCS describes the high as uplifting in the head and soothing in the body, meditative and relaxing overall. That is what consumers commonly report from Sour Diesel and OG Kush hybrids: an alert, mood-lifting beginning, followed by a calmer physical feel. At 26% THC, it is strong, so start low, wait before taking more and avoid combining it with demanding tasks. Dry mouth and dry eyes are commonly reported with strong hybrids. Effects vary by person, and we make no medical claims.

How strong is SSKUSH? THC content

QCS lists SSKUSH at 26% THC, with no CBD listed. That puts it in the high-potency group. Real numbers depend on your light, feeding, harvest timing and cure. If strength matters most to you, see our seeds over 25% THC, which includes this one.

Growing SSKUSH: flowering time and yield

Indoors, SSKUSH flowers in about 60 days and yields 475 to 550 g/m² at medium height, which suits most tents and rooms. Outdoors it is typically ready in early October with up to 670 g per plant. QCS rates it moderate and says the genetics resist common pests and mould, with the standard note that mould tolerant does not mean mould proof.

A key tip from QCS: it is a hungry plant early on, so provide calcium and magnesium from the start, particularly under LED lighting. Plan for a stretch in early flower, and use topping or training so light reaches the lower sites. Keep humidity in check late in flower, when the colas get dense. One customer saw a rough start, with missing leaflets and some deformities, but the plant recovered by week three or four and grew colas up to about four inches wide, reaching around 450 g wet weight. That is a reminder to be patient with young plants and keep the feeding stable.

What customers report

SSKUSH has nine reviews on our site and averages 4.1 out of 5. Several reviewers received it as a free bonus seed, which makes their feedback interesting but varied.

• Strong outdoor performance: one grower called it the best outdoor strain in northern Ontario, and another expected more than 1 lb per plant, with a grapefruit-like smell.
• Big colas: one grower reported colas that grew into massive four-inch monsters.
• Special flavour: one reviewer found the taste very particular, like wet cotton, and liked it.
• Service praise: several reviews praise fast shipping and good customer service.
• The honest complaints: one grower reported poor germination, with very small and slow seedlings. Another, who grew SSKUSH next to another strain, found his SSKUSH plants much smaller. A third reported a rough start before the plant recovered.

The picture: when it works, it is big and tasty, but results were mixed. Start with healthy seedlings, feed well and be patient.

Is SSKUSH right for you?

SSKUSH suits growers who want a high-THC, gassy hybrid with a balanced effect, medium height and a 60 day flowering time, and who are comfortable with a moderate difficulty level. It is a good match for indoor growers wanting 475 to 550 g/m² and for outdoor growers who can harvest in early October. It is less ideal for absolute beginners or anyone who dislikes a strong diesel smell.
