American Haze Feminised
Growing American Haze Feminised in New Zealand: a sativa at 24% THC, creative, energetic. Flowering window and height are on the page where we hold them, blank where we do not.
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 360.
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 American Haze Feminised
Latitude decides more about a American Haze crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 16/84 sativa 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 American Haze 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 65-70 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 American Haze Is Like
Reported effects cluster around creative, energetic. At 24% 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 16/84 balance shapes where it lands: head-forward and clear enough for daytime, though the ceiling arrives faster than beginners expect. 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
Pinene leads, limonene sits behind it, and caryophyllene runs underneath.
Temperature changes what you get. Vaporised low, around 180 to 188 degrees, limonene and caryophyllene come through cleanly while pinene stays in the background. Combusted, pinene dominates and the finer detail is largely lost. Same flower, two different experiences.
Who It Suits
Who does well with American Haze? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. Experienced growers specifically; this one scales with the quality of your environment.

Where American Haze Feminised Comes From
We hold no documented parentage for this cultivar, so none is shown. A blank here is an admission rather than an oversight β we would rather leave it empty than publish a lineage we cannot stand behind.
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.
