Alien OG Seeds

The three formats serve different buyer needs. Feminized seeds — available from Homegrown Cannabis CO, Dutch Seeds Shop, Pacific Seed Bank, and Seedsman — deliver the full yield potential of the Alien Kush x Tahoe OG Kush genetics, with 400–500g/m² indoors. Autoflower seeds, sold exclusively by Seed Supreme, complete their cycle in 8–10 weeks from seed and are better suited to buyers prioritizing speed and discretion over maximum output. Regular seeds from Herbies Headshop produce both male and female plants, making them the right purchase for breeders looking to work with Alien OG's balanced hybrid genetics rather than growers focused on end yield.

Verified specs place Alien OG at 20–28% THC, which puts it firmly in the high-potency category. That's a meaningful range, and the actual outcome depends significantly on which seedbank's genetics you purchase — not all breeders hit the upper end of that window consistently. When comparing seedbanks stocking Alien OG, it's worth checking whether they publish lab test results or third-party potency data for their specific phenotypes. Seedsman and Herbies Headshop tend to provide more detailed genetic documentation than smaller retailers. CBD content is less than 1%, so buyers looking for a balanced THC:CBD profile should look elsewhere.

Alien OG is rated intermediate difficulty, which is an honest assessment given its Tahoe OG Kush parentage — a lineage known for being particular about its environment. From a buying perspective, this means first-time growers should factor in the cost of potential crop underperformance when calculating value per seed. If you're newer to growing, the autoflower format from Seed Supreme may offer a lower-stakes entry point into this strain. More experienced growers who want the full 400–500g/m² yield and 28% THC ceiling should go straight to feminized seeds from Seedsman or Homegrown Cannabis CO.

Alien OG seeds are currently available from six seedbanks: Homegrown Cannabis CO, Dutch Seeds Shop, Pacific Seed Bank, Seed Supreme, Herbies Headshop, and Seedsman. Feminized seeds are the most widely available format, stocked by four of the six retailers. Autoflower seeds are exclusive to Seed Supreme, and regular seeds are only available through Herbies Headshop. When deciding where to buy Alien OG seeds, compare pack sizes (typically 3, 5, or 10 seeds), shipping policies to your region, and whether the seedbank offers a germination guarantee. Pricing can vary by 20–30% between retailers for the same seed type, so it's worth checking multiple listings before committing.
