American Strains Pack

American Strains Pack is bought for what comes off it, and the sourced figures are 300–400 g/m² under lights and 300–500 g/plant from a plant grown out. Those are ceilings, not promises — pot volume, light intensity and how honestly you feed decide where you land inside them. Run the numbers for your own tent with the yield calculator before committing to a pack size, and put it next to the rest of the high-yield strains if weight is the whole point.

This is three different cultivars in one pack, not three packs of the same seed. They divide evenly by pack size: a 3-seed pack is one of each, a 6-seed pack is two of each, a 15-seed pack is five of each. Each is its own plant with its own habit, which is worth knowing before you plan a tent around them.

• Blue Dream — a Californian hybrid: sweet berry, a loose-limbed body and a mild head lift behind it. The autoflowering version takes the timing decisions away from you.
• Green Crack — tangy citrus fruit and a sharp mental edge. Daytime, unambiguously — this is not one to reach for late.
• Alaskan Thunder Fuck — out of Alaska's Matanuska Valley. Pine on the nose, heavy resin on the trichomes, and euphoria that arrives with some force.

Because they are three distinct plants, they will not finish together. Give the tallest of them the headroom and expect to harvest in stages rather than all at once. In a New Zealand outdoor season that is an advantage: staggered ripening spreads the risk across the damp weeks of March and April instead of putting every plant at the mercy of one bad fortnight.

What the sourced data gives for this cultivar: 300–400 g/m² under lights, 300–500 g/plant from a plant grown outside. Reaching either is an environment problem before it is a genetics one.

Root volume sets the ceiling before a single flower forms. Under-pot a plant and no feeding schedule rescues it. Get the container right early and the plant does the rest.

Light is the second lever, and the one most growers get wrong in both directions — too little through veg, too much in late flower where it bleaches rather than builds. Steady beats aggressive.

The third is the fortnight around the flip. The stretch after the flip decides your final canopy shape, and it is the last moment training does anything useful.

Feed to the plant rather than the calendar. Our nutrient calculator gives a starting schedule; the plant will tell you where it is wrong. Worth a side-by-side comparison before you commit if weight is the deciding factor.

Reported effects cluster around energizing, happy, creative, uplifted. At 22% THC that is a meaningful figure rather than a decorative one, and the sensible approach with anything in this range is to start lower than you think and wait longer than feels necessary.

The 40/60 balance shapes where it lands: even-handed, with the dominant direction shifting by dose more than by time of day. Tolerance moves this more than any other variable, which is why two people describe the same jar differently.

Prefer something gentler? The CBD-forward strains range trades peak potency for balance.

Caryophyllene leads, limonene sits behind it, and myrcene runs underneath.

This trio is a common signature in well-regarded cultivars, which is not an accident: caryophyllene carries weight, limonene adds definition, myrcene keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.

Who does well with American Strains Pack? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. First-timers included — the genetics are forgiving.

Still deciding? The indoor-friendly genetics list is the narrower place to start.
