🧬 Genetics:

Alien Gas XXL Auto is part of a new generation of autoflowers developed to compete with top-tier photoperiod strains in every aspect: structure, resin production, stability, and yield. While Silent Seeds keeps the precise lineage confidential, it’s clear this hybrid inherits from elite OG selections, offering powerful characteristics typically only found in full-season plants. This auto was developed for demanding growers seeking top-shelf quality with shorter cycle times and ease of cultivation.

🌱 Plant Appearance and Cultivation:

Alien Gas XXL Auto displays explosive vegetative growth, especially during the first 20 days after germination. Its structure is compact and bushy, with numerous strong lateral branches and tight internodal spacing. The foliage is mid-sized and rounded, reminiscent of traditional OG Kush phenotypes.

In indoor setups, it reaches heights of 100 to 140 cm and responds very well to training techniques like LST or SCROG. Outdoors, under optimal sun and soil conditions, plants can reach up to 180 cm and yield over 1 kg of dry flower. Its uniform development and excellent genetic stability make it ideal for scaled professional grows as well as passionate hobbyists.

👅 Terpene Profile:

The aromatic richness of Alien Gas XXL Auto sets it apart. From mid-flowering onwards, the plant exudes strong notes of diesel, pine, and kush, with lemon zest and spicy undertones. These complex scents intensify after drying and curing, making it one of the most flavorful autos available. Whether smoked or used in resin extractions, this strain delivers a full-spectrum OG flavor that’s pungent, powerful and persistent.

🔥 Potency and Effects:

With THC levels reaching up to 28%, this strain offers a strong, full-bodied effect that clearly leans toward the Indica side. Expect an initial mental calm that transitions quickly into a long-lasting body stone, ideal for unwinding after a long day or for therapeutic use.

Alien Gas XXL Auto excels in managing stress, chronic pain, tension, and insomnia. Its deep relaxing properties make it best suited for nighttime use or for consumers looking for strong physical relief without overwhelming mental effects. Due to its potency, novice users should approach with caution and start slow.
