Killer Kush F1 Fast Version by Sweet Seeds

Killer Kush F1 Fast Version brings the West Coast’s most famous Kush into a faster photoperiod format. This feminized F1 hybrid, variety SWS52, is built on OG Kush, the Ocean Grown Kush that Sweet Seeds dates to around 1994 in Sunset Beach, Southern California, and it finishes in about 7 weeks of flowering.

Expect an extremely potent, 80% Indica plant with 18–25% THC, about 0.9% CBD and large, aromatic buds under a thick layer of resin. Its sweet, sour citrus bouquet carries exotic tones reminiscent of the Chemdawg-Diesel family, and the breeder lists three awards, including 1st Prize in the Indica category at the 1st St. Vincent and the Grenadines Cannabis Cup in 2023.

Lineage: OG Kush on a Faster Clock

Sweet Seeds crossed an elite clone of OG Kush with a selected third-generation autoflowering line that leans to the Indica side. This is the core of the F1 Fast Version line: a photoperiod clone combined with an autoflowering line to produce an early-flowering F1 hybrid that still depends on the light cycle.

So Killer Kush F1 Fast Version is not an autoflower. It needs 12/12 lighting indoors to begin flowering, and outdoors it responds to the shortening days. Besides the 2023 win, Sweet Seeds lists a 2nd Prize in the Outdoor category at the III Biomenorcannabis in Menorca (2017) and a 3rd Prize in the Indica category at the VI Copa Cannábica Expogrow in Irún (2017).

Aroma, Flavor and Effect

The nose opens sweet and citric with a sharp, sour bite, then deepens into floral, musky and hashish layers. Exotic fuel-like tones in the Chemdawg-Diesel style give the profile its West Coast edge. It is like squeezing a lemon over a block of old-school hash in a room that still smells faintly of gasoline.

The effect follows the Indica-heavy genetics: deeply relaxing and happy, with the body settling first and the mood lifting alongside. It is potent, so it fits slow evenings and quiet weekends better than busy afternoons.

Growing Indoors and Outdoors

Indoors, give it a short veg, switch to 12/12 and plan on roughly 7 weeks of bloom. Under good conditions, the breeder reports 400–600 g/m² (1.31–1.97 oz/ft²). The Indica structure stays fairly compact, so a Sea of Green with many small plants or a light topping and LST setup both work well. Keep humidity in check late in flower, since the large, dense buds pack in tight.

Outdoors, choose a sunny site, a quality soil mix and steady feeding. Sweet Seeds puts outdoor production at 350–600 g/plant (12.3–21.2 oz/plant) per plant. The short flowering phase helps the crop finish earlier than a standard OG Kush, and the breeder’s Menorca outdoor award shows it can perform in the open.
