What the seed lot did on the bench

Every lot is checked before it goes on the shelf, and the yield figures come from New Zealand growers who sent us a harvest weight against a batch code. This lot was read on 2026-09-10, from a tray sample of 200.

Opened on the bench: 96.5% of 200
Lot checked: 2026-09-10, at 21-24Β°C
Under lights here: 434-559 g/mΒ², across 14 grower reports
Outside here: 439-612 g/plant, across 5 grower reports

Outdoor figures come from a New Zealand season, so they run below what the same cultivar reaches somewhere with a longer, drier autumn. Treat them as what this plant does here. The full report for this lot sets out the method and the terpene panel.

About Sour Tsunami Feminised

Days 1 to 14. Sour Tsunami cracks on damp paper towel inside about two days and is through the medium by day three, given warmth and patience rather than intervention. Seedlings want humidity near 70% and no nutrients at all β€” the seed carries everything for the first week. By the end of the fortnight you are looking for even node spacing rather than height; a stretched seedling is a light problem, not a vigour signal. New to this? The free seeds on offer are a low-stakes way to practise the germination step.

Sour Tsunami Through the Grow

Weeks 3 to 6. Growth stops being tentative. This is when training earns its keep: bend rather than cut if you are unsure, because a bent branch recovers in a day and a topped one costs a week. Expect fairly even growth in both directions.

The transition. After the flip the plant may double. Whatever shape the canopy is at that point is roughly the shape you harvest.

Mid-flower. Bud sites fill and the aroma arrives β€” usually the point where extraction stops being optional. Feed heavier now, but watch the leaf rather than the schedule.

The last fortnight. Ease off nitrogen, drop the night temperature a little, and stop feeding before you think you should. Final height for this cultivar is published at Tall.

Harvest. Published window: 9 weeks. Trichomes decide. Cut in sections if ripening is uneven β€” most plants ripen top-down and there is no prize for taking it all at once.

What Sour Tsunami Is Like

Reported effects cluster around happy, relaxed, uplifted. At 7% 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.

The Terpenes

Limonene leads, caryophyllene sits behind it, and linalool runs underneath.

Temperature changes what you get. Vaporised low, around 180 to 188 degrees, caryophyllene and linalool come through cleanly while limonene stays in the background. Combusted, limonene dominates and the finer detail is largely lost. Same flower, two different experiences.

Who It Suits

Who does well with Sour Tsunami? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. First-timers included β€” the genetics are forgiving.

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

Where Sour Tsunami Feminised Comes From

Documented parentage is Sour Diesel Γ— NYC Diesel. Where a cultivar's origin is recorded we name it on this page; where it is contested or simply unknown, the field stays empty rather than being filled with something plausible.

We did not originate the cultivars in this catalogue and do not claim to have. What we do is select and stabilise the lines we sell, so that a pack grows out more uniformly than an unworked one β€” which matters more in New Zealand than in most places, because an outdoor grower here is working to a frost date rather than an open-ended season. The stabilisation programme sets out how that works and what it does not cover.

Every pack is covered by our germination promise: follow the method in the germination guide and seed that fails to open is replaced free within 30 days.
