About Royal King Seeds New Zealand
A seed shop for New Zealand growers, and honest about what it is
Royal King Seeds supplies 1,677 cannabis seed varieties to growers across New Zealand. We did not breed them — they come from established seed houses whose work we stock, catalogue and ship. What we add is a catalogue organised the way people here actually shop, strain data we are willing to stand behind, and growing guidance written for a Southern Hemisphere season.
What we actually are
We are a retailer. Every strain here was bred by someone else, most of them by seed houses with decades behind them, and our job is to get that genetics to your door with the packaging discreet and the description accurate.
That is a less impressive story than an in-house breeding programme, and it is the true one. It also sets a useful limit on what we are entitled to tell you: we can report what a breeder published about a strain and what growers consistently report back, and we cannot claim laboratory results we never commissioned or a stabilisation history we did not run.
Orders ship in plain, unbranded packaging with tracking, to addresses across all sixteen regions on both islands. Prices are in New Zealand dollars with GST included and no card surcharge, so the price on the shelf is the price at checkout. See shipping and delivery for timings, or the FAQ for the questions we get most.
How we handle strain information
Four rules, mostly about what we will not do.
We source, we do not breed
The genetics in this catalogue were bred by established seed houses — the names behind the classics and the modern dessert lines alike. Where we know which breeder originated a strain, the strain page says so. We are the shop, not the breeding programme, and telling you otherwise would make every other claim on this site worth less.
A blank field beats an invented one
Flowering time, height, yield and THC come from the breeder or a published reference. Where no figure exists we leave the field empty rather than filling it with a plausible-looking range. That is why some strain pages carry less data than others — the gaps are real, and hiding them would only cost you a season.
A guarantee, not a lab result
We guarantee 95% germination and replace anything that falls short — same strain, same pack size, free of charge. That is a promise we honour, not a measurement we are reporting, and the difference matters: we will not quote you a lab result or a certificate of analysis, because we commissioned neither. What decides your outcome is method — damp paper towel at around 22°C, kept dark, never allowed to dry out, and a full week before you call it.
Written for this country, not converted to it
Our growing content is written for growing at 34 to 47 degrees south — plant out from October, harvest March to May, and plan around a wet autumn rather than a dry one. Most cannabis growing advice online is written for the Northern Hemisphere and is six months out of step by the time it reaches you.
Why a New Zealand catalogue looks different
New Zealand is temperate oceanic end to end. There is no tropical zone and no dry interior, so the constraint on an outdoor grow here is almost never heat — it is how much rain falls while the plants are in flower, and how early the first frost arrives.
That changes what is worth stocking. In Northland, Auckland and the Bay of Plenty the season is long enough for almost anything, but February and March humidity means an open bud structure matters more than a headline THC figure. Nelson, Tasman and Marlborough get the highest sunshine hours with the lowest summer rain, which makes them the most forgiving outdoor conditions in the country. In Canterbury, Otago and Southland the first frost sets the deadline, which is why autoflowering seeds and fast-flowering genetics dominate down there.
If you would rather not work through 1,677 options, the strain finder narrows it by space, experience and region in under a minute, and the growing guides cover the parts of a season that catch people out here.
One thing we will not do
Seeds are sold as adult collectibles and for genetic preservation. We do not tell you what the law permits where you live. That varies, it changes, and getting it wrong is your risk to carry, not ours to guess at — so knowing what applies to you before you order is your responsibility. Nothing on this site is legal advice. The legal notice sets this out in full.
