Blackstar Kush Auto is a knockout indica-leaning hybrid bred by pairing Black Toffee Auto with the powerhouse Rockstar Kush Auto.

Designed for fans of deep, couch-locking effects and rich, fuel-heavy aromas, this strain delivers on every front—yield, flavor, and strength.

Expect jet-black sugar leaves, trichome-soaked buds, and a knockout stone that sets in hard and fast.

With a longer flowering time of 85–90 days, Blackstar Kush rewards the patient with top-shelf results that rival photoperiods.

It’s the kind of plant that makes its presence known before you even light it up.

Genetics & Origins
Blackstar Kush Auto was created through a small-batch selection of Black Toffee Auto from Green House Seed Co., hit twice with Rockstar Kush Auto pollen.

After a 30-seed test grow, only one plant was chosen to carry the torch—and the result is this dark, dense, diesel-drenched hybrid that shines with indica dominance.

Her dense buds, dark foliage, and sticky trichome coverage scream potency.

She’s a heavy yielder with serious bag appeal, bred for lovers of old-school gas strains with modern autoflower performance.

Effects & Experience
This one hits low and slow—until it doesn’t. Blackstar Kush creeps in with a relaxing wave of calm that quickly becomes a full-body melt.

Your eyelids get heavy, your limbs relax, and the day’s stress disappears. Best saved for evenings, post-dinner wind-downs, or anytime you want to truly shut it down.

Flavor & Aroma
• Loud diesel and raw gas dominate the profile
• Earthy kush and toasted sugar backend
• Aroma fills the room on grind and only gets stronger when smoked
• Not subtle—this one announces itself

Why Choose This Strain?
Blackstar Kush Auto is for the heavy hitters—growers and smokers who love rich fuel terps, knockout potency, and photoperiod-tier bud quality.

It’s a true heavy indica in autoflower form, ready to sink your battleship and keep you coming back for more.
