Alien Gas XXL Auto | Silent Seeds

Alien Gas XXL Auto from Silent Seeds is a top-tier autoflowering strain that powerfully proves modern auto-flowering cannabis varieties are no longer living in the shadow of their photoperiod relatives. With a THC content of up to 28 % and massive yields reaching up to 650 g/m² indoors or 1.200 g per plant outdoors, this strain raises the bar. Bred from Face Off OG and MAC Auto, it combines rugged genetics with impressive performance, delivering everything discerning growers expect from a next-gen autoflower: stability, potency, yield, and an intense terpene profile.

Classic Kush flavor with an interstellar twist

Alien Gas XXL Auto stays true to its OG roots while taking them to a whole new level. On the first hit, strong diesel notes burst onto the palate with a bold spiciness. But it doesn’t stop there — pine resin, zesty lemon, and a whisper of exotic spice round out the profile, creating a deeply flavorful, full-bodied, and surprisingly layered experience. This terpene blend hits all the right notes for Kush connoisseurs while bringing a fresh, almost otherworldly edge to the table.

Up to 28% THC: Deep physical relaxation

With a THC level hitting up to 28 % and clear Indica dominance, Alien Gas XXL Auto delivers what real deep-body relaxation means. The effects come on slow but make their intentions known quickly — your mind goes blank, your body feels heavy. Stress, tension, and daily chaos fade away as you sink further into the couch. It’s the perfect strain for evenings when you want to completely unwind and just relax.

Growing Alien Gas XXL Auto: Bushy structure, XXL yields & reliable performance

Alien Gas XXL Auto isn’t lightweight — neither in effect nor in growth. The plants strongly resemble OG Kush: bushy, heavily branched, with tight internodes and sturdy side branches. Indoors, this strain produces generous harvests that rival any photoperiod strain. After only 58 to 63 days from seed, these 70 to 110 cm tall plants can yield up to 650 g/m² under optimal conditions. Outdoors, they can reach heights of up to 180 cm and deliver an incredible 1.200 grams per plant under ideal outdoor conditions. It's an excellent choice for growers seeking maximum output with minimal effort.
