Royal King Genetics — Seed-Lot Testing

Germination rate: 98.2% (n=175)
Last QC test date: 2026-04-23
Indoor yield: 465-588 g/m² (avg across 9 verified grower reports)
Outdoor yield: 503-768 g/plant (avg across 8 verified grower reports)

About American Strain Mixpack Feminised

Days 1 to 14, seed to fourth node: Expect American Strain Mixpack to crack in roughly 48 hours on damp paper towel and to break soil by day three. Growth is even and unhurried — four solid nodes by day 14, spaced somewhere between the two parent types. Damping off is rare if you hold near 70% humidity through this stage.

Weeks 3 to 6, building the frame: One top at node four and a light tie-down is all it asks for. Six leaders and an even canopy across roughly 70 x 70 cm, then it is ready to flip.

Bloom, weeks 1 to 810: The 35/65 character becomes obvious here. Caryophyllene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: 400–500 g/m². Height: 80–120 cm. Tested at 21% THC. Difficulty: intermediate.

What's Inside the American Strain Mixpack Feminised

The American Strain Mixpack Feminised is an assortment of three separate strains rather than a single cultivar, and every pack splits evenly between them. The 3x5=15 option is 5 seeds of each strain, 3x10=30 is 10 of each, 3x15=45 is 15 of each, and 3x20=60 is 20 of each.

  • Blue Dream — a California hybrid with sweet berry flavour, full-body relaxation and a gentle cerebral lift. The autoflowering version keeps the grow simple.
  • Green Crack — a sharp, energizing sativa with tangy citrus-fruit flavour and an invigorating mental buzz — a daytime strain.
  • Alaskan Thunder Fuck — a sativa from Alaska’s Matanuska Valley, known for intense euphoria, a piney aroma and heavy resin production.
The specifications listed elsewhere on this page describe the pack as a whole; each strain has its own flowering time, structure and terpene profile.

Bloom Through to Jar

Weeks 4 to 6. This is where the plant stops looking like a frame and starts looking like a crop. Development stays even across the bud sites, and the canopy work done in veg pays off now — eight comparable colas rather than one dominant top over a set of also-rans. Trichomes should be visible without magnification from about week four.

Weeks 808 to 810, ripening. Drop to plain water for the final ten days. The caryophyllene carry gets strong enough that carbon filtration stops being optional in a residential street. Trichomes run clear to milky across the last fortnight, amber showing on sugar leaves before it reaches the calyxes; around 15% amber on the calyxes themselves is a common place to cut.

Drying and curing. Whole-plant hang in the dark at 17°C and 58% humidity for roughly 12 days — when stems snap instead of bending, it is ready for glass. Burp twice daily for the first fortnight, then once daily through weeks three and four. Finished weight should land near the 400–500 g/m² estimate. The myrcene note comes through markedly stronger after curing than it did at harvest, which is the clearest evidence that a cure builds flavour rather than merely preserving it.

Difficulty: intermediate. In flower for 8–10 weeks. Stands 80–120 cm. Indoors it returns 400–500 g/m². Outdoors, 400–600 g/plant a plant. Feminised seeds.

What American Strain Mixpack Is Like to Use

The effects most commonly reported for this cultivar are relaxed, happy, euphoric. At 21% THC it sits in a bracket where flexibility is the point. Lower doses read clear and functional in the morning, higher doses read relaxed in the evening. Because the 35/65 split is even, direction is set by how much you take rather than fixed by the genetics. The Caryophyllene/Myrcene pairing leaves a warm spice that dries slightly on the exhale on the palate.

Where it fits: most occasions, with the dose adjusted to whatever the situation asks for.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Humulene underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of American Strain Mixpack tends to get a reaction the first time it is opened after curing. Caryophyllene sets the anchor, myrcene fills the middle, and humulene sits in the background doing the work that separates this from every other strain built on the same primary terpene.

Suitability and Recommendations

American Strain Mixpack is a reasonable fit for growers with the basics already in place. Understand pH, know roughly what nutrient ratios do, and be able to hold a light cycle — it will not carry you, but it does not punish the occasional slip either. Photoperiod genetics leave size and timing in your hands — hold it in veg for a bigger plant, or flip early when headroom is the constraint. A September-to-May outdoor season comfortably covers a 8–10 weeks bloom in the frost-free provinces. Posted discreetly anywhere in South Africa, with sourced grow figures shown on every strain page.

Backcross Stabilisation (BX2) — modern hybrid fixing
Stabilisation Notes — What This Means for Your Grow

American Strain Mixpack carries clone-derived parents from the late-2010s. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and trichome production run uniform across the population.

Breeding Goal

Pin the trichome production that came out of the original American Strain Mixpack cross.

Selection Focus

Chosen for terpene profile, vigour, structure and finish-time consistency.
