501st OG Feminised
501st OG Feminised, a indica listed at 18% THC and described as relaxed, sleepy, happy. Posted unbranded and tracked to any New Zealand address, with the grow figures we could trace on the listing.
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 140.
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 501st OG Feminised
Will 501st OG 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. Indica structure copes better with a short season, so the honest answer depends on where you are. The regional notes below are the short version.
Questions New Zealand Growers Ask About 501st OG
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 — and uninterrupted means exactly that.
When is it ready? Trichome colour, not the calendar. The published window is 7-9 weeks, which is a reasonable figure to plan around, but the plant decides.
Is it beginner-friendly? It is rated easy. That means it tolerates the mistakes everyone makes in their first season.
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 — or the outdoor-season range if the season is your constraint.
How does it arrive? Plain, unbranded packaging with tracking — the detail is on the shipping page.
Effect Profile
Relaxed, Sleepy, Happy is the consensus, and consensus is worth exactly what it sounds like — a starting point. 18% THC sets the scale; linalool and the terpenes alongside it shape the character rather than the strength.
Onset is quick by inhalation and slow by ingestion, which is where most bad experiences begin. Expect the weight to settle physically within the hour.
If potency is what you are shopping for, the high-THC seeds category is sorted for it.
The Terpenes
Linalool leads, myrcene sits behind it, and caryophyllene runs underneath.
Aroma is not fixed at harvest — 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
501st OG is rated easy. That makes it a reasonable first grow — it survives inconsistent watering and imprecise feeding without collapsing, which is what a first season mostly consists of. 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 501st OG Feminised Comes From
Documented parentage is Skywalker OG × Rare Dankness #1. 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 — 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.
