Royal King Genetics — Seed-Lot Testing

Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-04-10 on 300 seeds.

Germination rate: 96.6% (n=300)
Last QC test date: 2026-04-10
Indoor yield: 422-588 g/m² (avg across 14 verified grower reports)
Outdoor yield: 532-866 g/plant (avg across 5 verified grower reports)

About American Strains Pack

The way to plan American Strains Pack is backwards from the day you intend to cut, with 300–400 g/m² per square metre indoors and 300–500 g/plant per plant outdoors as the figures you are working toward, at 22% THC. Count 9–11 weeks back from that date and you have your flip date. Weight comes on evenly across 9–11 weeks, with a late surge that punishes impatience. The 40/60 balance gives you stacking density and broad trichome cover together. Outdoors, late March to late April is the sweet spot — after the summer humidity has broken, before the first Highveld frost.

What's Inside the American Strains Pack

The American Strains Pack is an assortment of three separate strains rather than a single cultivar, and every pack splits evenly between them. The 3-seed pack is 1 of each strain, the 6-seed pack is 2 of each, and the 15-seed pack is 5 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.

Where the Weight Actually Comes From

Yield on American Strains Pack — the 300–400 g/m² indoors and 300–500 g/plant outdoors quoted above — is decided in three short stretches of the 9–11 weeks bloom rather than evenly across it.

The first ten days after the flip. Whatever stretch happens here sets your canopy, and an uneven canopy wastes light for the remainder of the grow. Stretch of 30-40% is normal. One round of low-stress training on the tallest shoots levels it out.

Weeks three to five. This is when caryophyllene production climbs, and it answers to the gap between day and night temperature rather than to either number on its own. Keep at least 6-8°C between them. Outdoor growers in the interior provinces get that swing free in March and April; indoors, aim for 25-26°C lights-on against 18-20°C lights-off, with potassium-led bloom feed at EC 1.6-1.8.

The last ten to fourteen days. Stop feeding, flush with pH-corrected water, and read trichomes daily under a 60x loupe. Cut at 10-15% amber to keep both sides of the hybrid in play. Outdoors that usually lands between late March and mid-April.

Difficulty: easy. In flower for 9–11 weeks. Stands 100–180 cm. Indoors it returns 300–400 g/m². Outdoors, 300–500 g/plant a plant.

Aroma, Flavour and Effect

The first thing American Strains Pack does at 22% THC is settle a warm peppery spice at the back of the throat. The energizing, happy, creative, uplifted effects follow within minutes, across head and body at once. Thinking stays clear while muscle tension drains off, which leaves the dose as the deciding factor — light for the afternoon, heavier and it moves into the evening without a jolt. Limonene sits underneath all of it, adding a brightness that offsets any heaviness.

The Aromatic Three

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

Suitability and Recommendations

Who does well with American Strains Pack? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions. Sent nationwide in plain, unbranded packaging, with sourced grow data on every strain page.
