XJ-13 Feminised
Hybrid genetics for a New Zealand grow. XJ-13 Feminised carries a listed 23% THC and reads energetic, happy, relaxed. Priced in NZD, GST included, delivered nationwide.
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 2026-09-13, from a tray sample of 420.
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 XJ-13 Feminised
Will XJ-13 finish outdoors in New Zealand? In most of the country, yes. The outdoor window runs October to April, and a photoperiod finishes as the autumn light shortens, so the question is whether your first frost arrives before it does. Balanced genetics adapt to most of the country, so the honest answer depends on where you are. The regional notes below are the short version.
Questions New Zealand Growers Ask About XJ-13
What medium suits it? Living soil rewards flavour, coco rewards control and speed. Neither is wrong. Choose the one you will actually maintain.
How much light? More in veg than growers expect, less in late flower than they think. Twelve hours of uninterrupted dark triggers flowering β and uninterrupted means exactly that.
When is it ready? Trichome colour, not the calendar. The published window is 9-10 weeks, which is a reasonable figure to plan around, but the plant decides.
Is it beginner-friendly? It is rated intermediate. That means basic competence with pH and feeding is enough.
Where do I put it? Indoors it is predictable; the indoor-friendly genetics list covers what performs in a tent. Outdoors, see the regional notes above β or the outdoor-season range if the season is your constraint.
How does it arrive? Plain, unbranded packaging with tracking β the detail is on the shipping page.
What XJ-13 Is Like
Reported effects cluster around energetic, happy, relaxed. At 23% 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 50/50 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.
This trio is a common signature in well-regarded cultivars, which is not an accident: limonene carries weight, caryophyllene adds definition, linalool keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.
Who It Suits
Who does well with XJ-13? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. Anyone past their first grow.
Still deciding? The indoor-friendly genetics list is the narrower place to start.

Where XJ-13 Feminised Comes From
Documented parentage is Jack Herer Γ G13 Haze. 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.
