What Is Power Mix American? Four Iconic US Genetics in One Pack
Power Mix American brings together four of the most recognisable American cannabis genetics available from Pyramid Seeds — Gelato, Gorila, Romulan, and Cookies USA. All four share the hallmarks of modern American breeding: complex terpene profiles, high THC (24–28%), dense resinous bud structure, and the kind of effect depth that made these genetics global standards. With 12 feminized seeds (3 per strain) and flowering times ranging from 43 to 58 days (LED), this pack lets you run a direct comparison of four distinct American profiles in a single cycle.
Two strains in this pack — Romulan and Cookies USA — also carry unusual colour expression, adding visual variety to the grow alongside the terpene and effect diversity.
The 4 American Strains Inside Power Mix American
Gelato: Sunset Sherbet × Thin Mint GSC — The Cream Standard
Gelato is one of the most sought-after American genetics of the last decade — a balanced hybrid (45% sativa / 55% indica) from Sunset Sherbet crossed with Thin Mint Girl Scout Cookies. THC 25–27%, with a rich candy, cream, earthy and fruit aroma that delivers on the flavour promise of its Cookie genetics lineage. Effect: euphoric and powerfully relaxing. Flowering time: 53–58 days (LED). The highest-yielding strain in the pack at up to 500 g/m² indoor (1000 g/1.5m² under expert LED). If you've been looking for gelato seeds from a proven European breeder, this is the reference version.
Gorila: Chem Sis × Sour Dubb — Euphoric Power with Complex Terpenes
Gorila draws from the same genetic pool that produced the original Gorilla Glue — built on Chem Sis and Sour Dubb, two of the most resin-forward American genetics available. Balanced hybrid (45% sativa / 55% indica), THC 25–27%, with a complex candy, citrus, pine and earthy aroma profile. Effect: euphoric and relaxing. Flowering time: 49–56 days (LED). Easy to grow and one of the most versatile strains in this pack — strong enough for experienced growers, approachable enough for intermediates. Indoor yield up to 400 g/m².
Romulan: Pure Romulan Genetics with Unusual Colour
Romulan is the most indica-dominant strain in this pack at 75% indica, built on pure Romulan genetics — a West Coast American classic known for its heavy sedative effect and distinctive appearance. THC 24%, candy and pine aroma with spicy depth, and an effect that moves from euphoria through relaxation to sedation. Flowering time: 43–53 days (LED) — the fastest finisher in the pack. Unusual colour expression means this strain often develops purple and dark tones in the final weeks, making it one of the most visually striking plants in the grow. Indoor yield up to 450 g/m².
Cookies USA: Durban Poison × OG Kush with Pastry Aroma
Cookies USA completes the pack with the most distinctive aroma of the four — candy, earthy, fruit and unmistakably pastry-like terpene expression that reflects its Durban Poison and OG Kush lineage. 70% indica, THC 25–28% (the highest ceiling in the pack), with a meditative, powerfully relaxing effect. Also carries unusual colour genetics. Flowering time: 49–56 days (LED). The highest THC potential in this pack and the best choice for growers who want the full Cookies experience with genuine OG Kush depth behind it. Indoor yield up to 550 g/m² — Extra Large.
Terpene Profiles: The Common Thread Across All Four
What unites these four American genetics beyond their origin is terpene complexity. All four share a candy/sweet base, but each adds its own layer:
- Gelato — candy + cream + fruit. The richest, most dessert-like profile in the pack.
- Gorila — candy + citrus + pine + earthy. The most complex and fuel-forward aroma.
- Romulan — candy + pine + spicy. Sharper and more resinous than the others.
- Cookies USA — candy + earthy + fruit + pastry. The most distinctive and immediately recognisable.
Running all four side by side gives you a direct terpene comparison across the American cannabis spectrum — useful data for identifying which profile you want to build future grows around.
Flowering Time Comparison (LED)
- Romulan — 43–53 days
- Gorila — 49–56 days
- Cookies USA — 49–56 days
- Gelato — 53–58 days
Romulan finishes first — harvest it when trichomes peak, then let Gorila and Cookies USA follow, with Gelato closing the cycle. Staggered harvests across 10–15 days mean you're processing manageable batches rather than everything at once.
Who Should Grow Power Mix American?
Power Mix American is built for growers who want to explore the depth of American cannabis genetics without running four separate grows. If you've grown one of these strains before and want to see how the others compare in your specific environment, this pack gives you that data in a single cycle. The unusual colour expression on Romulan and Cookies USA adds visual interest to the grow alongside the genetic diversity.
Three of the four strains are rated moderate difficulty, with Gorila the only easy-rated strain in the pack. This isn't the most beginner-friendly pack in the range — but it's entirely manageable for growers with a couple of completed grows behind them.
