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 2026-09-07, from a tray sample of 340.

Opened on the bench: 98.8% of 340
Lot checked: 2026-09-07, at 20-23Β°C
Under lights here: 393-489 g/mΒ², across 11 grower reports
Outside here: 514-762 g/plant, across 8 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 White Widow Auto

Latitude decides more about a White Widow crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 50/40 hybrid into two different plants: a Kaitaia grower fights airflow and humidity through a muggy February, while a Southland grower is counting the weeks to first frost. Neither problem is about heat. If frost rather than heat is your limit, the strain finder sorts the catalogue by finishing time.

Growing White Widow in New Zealand Conditions

Indoors the outside world stops mattering and the job is control. Outdoors it is the whole brief.

Upper North Island β€” Northland, Auckland, Waikato, Bay of Plenty. The longest season in the country and the wettest finish. Bud rot, not sunshine, is what costs you a crop here, so plant where morning air moves and thin the interior early rather than admiring a dense canopy in January. More open flower architecture is an advantage through a humid autumn.

Lower North Island. Hawke's Bay and Gisborne are the driest and sunniest stretch; Taranaki, ManawatΕ« and Wellington trade that for rain and wind. Wind decides how tall you let a plant get more than the genetics do.

South Island. Nelson, Tasman and Marlborough offer the best outdoor conditions nationally β€” high sunshine hours, low summer rainfall. Canterbury, Otago and Southland run a genuinely short season where flowering runs 50-55 days (harvest 70-85 days after germination) is the number that matters, because everything is a race against the first frost. An autoflower sidesteps this by finishing on its own clock. If your season is short, the autoflowering indica list is the better starting point.

What White Widow Is Like

Reported effects cluster around euphoric, relaxed, uplifted. At 26% 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 50/40 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

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

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

Who It Suits

White Widow is rated easy. That makes it a reasonable first grow β€” it survives inconsistent watering and imprecise feeding without collapsing, which is what a first season mostly consists of. Being an autoflower removes light-cycle management entirely, which suits balcony growers and anyone wanting a fast turnaround.

Shipped nationwide in plain packaging. Every strain page carries whatever grow data we could actually source, and nothing we could not.

Where It Sits

A balanced hybrid. We do not have an indica-to-sativa split for this one that we can stand behind, so it is left out rather than estimated.

Where White Widow Auto Comes From

Documented parentage is Brazilian Sativa (Landrace) Γ— South Indian Indica (Landrace). 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.
