Alien Gas XXL Auto - Silent Seeds Face Off OG x MAC Auto

Product detailed description

Alien Gas XXL Auto: Premium US genetics with XXL harvest

We present Alien Gas XXL Auto, a premium, indica-dominant hybrid (70 % Indica / 30 % Sativa) created in collaboration with a legendary breeder. It is the result of crossing two elite American genetics: Alien OG and Mendo Breath. The aim was to create a robust auto-flowering plant with a uniquely complex profile and massive production potential.

Thanks to its vigour and ease of cultivation, it is an excellent choice for growers of all levels who are looking for reliability and top-quality results.

Growing characteristics and profile

One of its main advantages is its complete life cycle lasting 75 to 85 days from germination to harvest. The plant grows vigorously into a robust Christmas tree-like shape and reaches a height of up to 1.3 metres. It features good spacing between nodes and strong side branches that can easily support the weight of heavy flowers.

For optimal results, we recommend planting the seeds directly into the final pot with a volume of at least 15-20 litres and adding 30 % coconut substrate to improve aeration and root development.

XXL harvest and flower structure

Alien Gas XXL Auto is an XXL-yielding strain. In indoor conditions, you can expect a massive harvest in the range of 500–600 g/m², while outdoors one plant can produce 125 to 250 grams. The flowers are dense, round and compact, often compared to golf balls, and are celebrated for their exceptional resin production, which covers them in a thick, sticky layer of trichomes.

Sophisticated terpene profile

The defining feature is its intense, complex and sophisticated sensory profile. The aroma is a rich and exotic blend of sweet and fruity notes, specifically grapes and berries, layered with fresh citrus and floral hints of lavender. All of this is underpinned by a deep, earthy and peppery Kush background.
