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 2026-09-16, from a tray sample of 280.

Opened on the bench: 96.8% of 280
Lot checked: 2026-09-16, at 20-23Β°C
Under lights here: 423-557 g/mΒ², across 7 grower reports
Outside here: 507-747 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 Ecto Cooler Feminised

Latitude decides more about a Ecto Cooler crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 77/23 indica 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 Ecto Cooler 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. Tight indica flower structure is the risk factor to manage, and it is manageable.

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 55-65 days is the number that matters, because everything is a race against the first frost. A greenhouse or polytunnel buys the fortnight that makes the difference. If your season is short, the outdoor-season list is the better starting point.

What Ecto Cooler Is Like

Reported effects cluster around relaxed, sleepy, happy. At 18% 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 77/23 balance shapes where it lands: body-forward, better suited to an evening than a task list. 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

Linalool leads, myrcene sits behind it, and caryophyllene runs underneath.

Aroma is not fixed at harvest β€” it develops. Fresh flower leads hard with linalool; three or four weeks in sealed glass at a stable 16 to 18 degrees lets myrcene and caryophyllene come forward as the sharper volatiles clear. Jars opened at week one and week five smell like different plants.

Who It Suits

Ecto Cooler is rated intermediate. That sits in the middle β€” you want a working understanding of pH and feeding, but nothing exotic. Being a photoperiod means you decide when it flowers, and therefore how big it gets.

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

Where Ecto Cooler Feminised Comes From

Documented parentage is California Orange Γ— Gorilla Biscuit. 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.
