Cannabis Seeds for New Zealand β From Northland Humidity to Southland Frost
New Zealand runs from 34Β°S to 47Β°S β a wider spread than most growers realise, and the reason a strain that finishes comfortably in Kerikeri can be caught by frost in Central Otago. Our catalogue is organised around that: feminised photoperiods for growers who want to control the flip, autoflowering genetics that finish before the autumn rain sets in, and CBD-forward cultivars. Prices in NZD, GST included.
Where a strain has no published flowering time or yield from a breeder or reference source, we leave the field blank rather than fill it with a plausible number. That is why some strain pages show fewer figures than others.cultivation guides for region-specific germination techniques.
What Actually Changes When You Grow in New Zealand
Two things drive almost every outdoor decision here, and neither is potency. The first is the calendar: the season runs spring to autumn, so a Northern Hemisphere guide has every month exactly wrong. The second is water. New Zealand's autumn arrives damp rather than dry, which makes the last three weeks of flower the riskiest part of the grow β and makes finishing speed and bud structure matter more than headline yield.
A Season That Runs the Other Way
Longest days fall around the summer solstice in December, not June. Outdoor photoperiods go out after the last frost in spring and finish as the light drops through March and April. Nearly every grow guide online is written for the opposite hemisphere, so the months in them are six out of step.
Twelve Degrees of Latitude
From Cape Reinga at roughly 34Β°S to Stewart Island near 47Β°S, New Zealand covers a wider latitude band than most growers account for. A cultivar that finishes comfortably in Northland can still be standing in flower when the first frosts reach Central Otago, which is why finishing time is the single most useful number on a strain page here.
A Wet Autumn, Not a Dry One
This is the difference that catches people out. The risk in late flower is not heat stress, it is botrytis. Dense, tightly packed colas hold moisture through a damp March, so open bud structure and mould resistance are worth more than an extra fifty grams on paper.
Frost Sets the Deadline in the South
Inland Canterbury, Otago and Southland can see frost from April onward, and in some seasons earlier. That compresses the usable window considerably. Short-flowering photoperiods and autoflowers started early are the practical answer, rather than long-season sativas that need until May.
Wind Is a Structural Problem
Wellington, the Canterbury nor'wester and exposed coastal sites put real mechanical load on plants carrying weight in late flower. Sturdy, shorter-internode plants and early training hold up where a tall, top-heavy phenotype snaps.
Short Season Favours Autoflowers
An autoflower runs on its own clock, typically finishing ten to twelve weeks from germination regardless of daylength. In the lower South Island that can be the difference between harvesting and not, and it allows a second run in the warmer north.

The strains most often ordered from this catalogue. Read the flowering time against your own frost date before choosing. It follows what actually sells, and nothing else β there is no feedback loop or germination reporting behind it, and we are not going to imply one.
Choosing Cannabis Seeds for New Zealand Conditions
Most strain pages sell you on potency. Potency is the least useful number when you are deciding what to actually put in the ground in New Zealand, because the thing that decides whether you harvest is timing, and timing here is tight.
Work backwards from your first frost, not forwards from germination. In Northland that gives you a long, generous window and your real enemy is the humidity that arrives with autumn. In Southland the window may be short enough that a twelve-week photoperiod simply does not fit, and an autoflower started in early spring is the only version of the plan that finishes. Between those two extremes sit roughly twelve degrees of latitude, which is a bigger practical spread than the size of the country suggests.
That is why finishing time is the field worth reading first on any strain page here, ahead of yield and ahead of THC. Where we have a flowering figure from the breeder or a reference source, it is on the page. Where no published figure exists, the page shows nothing rather than a generic range.

Reading a Flowering Time Against Your Own Frost Date
βΌ
A flowering time is not a harvest date. For a photoperiod it is the span after you flip, or after natural daylength drops far enough outdoors β so the useful sum is your realistic flip date plus the flowering window, checked against when frost typically arrives where you are. In much of the North Island that arithmetic is comfortable. Inland in the south it is often the constraint that decides the whole grow.
Autoflowers behave differently. They run on an internal clock, usually ten to twelve weeks from germination regardless of daylength, which makes them predictable to schedule and far easier to fit into a short season. That predictability, rather than any yield advantage, is why they suit the lower South Island.
Feminised, Regular and Autoflowering: What the Labels Mean
βΌ
Feminised seed is bred so that effectively every plant comes up female, which is the sex that carries the flower. Sow unfeminised seed and about half the pots turn out male β plants you have to spot and remove before they pollinate the rest and turn a crop into a seed run. The feminised shelf runs to 1,254 varieties, from compact indica cultivars suited to tight grow tents through to stretchy sativa-dominant hybrids that thrive outdoors. The catch, and it is a small one: a feminised photoperiod plant still waits for you to shorten the light, from 18 hours down to 12, before it will bloom.
Autoflowers: Set-and-Forget Genetics for Faster Results
βΌ
Autoflowering seed carries ruderalis in the background, and that is what makes the plant count weeks instead of daylight hours. Bloom usually starts three or four weeks after the seed opens, and the whole cycle is finished somewhere between eight and twelve. They stay compact β usually 60 to 120 centimetres β and they forgive the errors that end a photoperiod grow. The reason we point first-time growers at them is not a statistic; it is that they remove the decision beginners most often get wrong, which is when to switch the plant into flowering.
Matching Genetics to Where You Are in New Zealand
βΌ
New Zealand's climate changes with latitude far more than with distance inland, and the practical spread is wider than the country's size suggests. The upper North Island β Northland, Auckland, Waikato, Bay of Plenty β gives the longest season and the most growing time, at the cost of humidity that peaks exactly when flowers are filling. The eastern strip, from Gisborne through Hawke's Bay and across to Nelson and Marlborough, is drier and sunnier, which tolerates longer-flowering cultivars. The lower South Island is the constraint: a short window, frost from April inland, and a strong case for autoflowers or fast photoperiods. Choose on finishing time first, then on everything else.
Why Some Strain Pages Show Fewer Numbers Than Others
βΌ
This site publishes no yield figures of its own, and no customer-reported averages, because it has none to publish. What appears on a strain page is the figure the breeder or a reference source published, shown with its source. Where none exists the field is blank. Treat any per-plant number β here or anywhere β as a ceiling under that grower's conditions rather than a forecast for yours: pot size, light, feeding and training move the result far more than genetics alone.
How Our Discreet Shipping Operates
βΌ
Orders ship in plain, unbranded outer packagingβ no logos, no company name on the outside, and no description of the contents. Delivery is tracked to addresses on both islands. Rural and remote deliveries take longer than main-centre addresses.
Potency, Cannabinoids, and Choosing by Desired Outcome
βΌ
At the strong end of the catalogue sit the cultivars listed above 25% β Girl Scout Cookies, Bruce Banner and the White Widow line among them. Worth reading the listing rather than the reputation: Gorilla Glue has a bigger name than its listed 21% suggests. At the other end, CBD-forward seed is bred for a different cannabinoid balance β 10 to 20% cannabidiol with THC well below the rest of the catalogue. A balanced 1:1 hybrid sits between the two. What any of them does for a person is not something we will tell you: we describe how plants grow, and the rest is a question for someone qualified to answer it. Our calmer end of the catalogue is grouped by the effects the source descriptions name, nothing more.
Storing Seeds Between Seasons
βΌ
Seeds keep best cool, dark, dry and sealed. An airtight container with a desiccant sachet in a fridge is more than adequate; the thing that actually degrades viability is repeated temperature swing and the condensation that comes with it, so a container opened daily in a warm room is worse than one left closed in the cold. Avoid the freezer. Label the container with the strain and the date you received it β a year on, that is the detail nobody remembers.
Recommended Strains for Every Experience Level
βΌ
For a first grow, the useful filter is forgiveness rather than potency: an autoflower removes the light-cycle decision entirely, and a shorter plant is easier to manage in a tent or on a balcony. Start from the autoflowering range and sort by finishing time, and if you are in the lower South Island treat anything over twelve weeks from germination as optimistic for an outdoor run.
- First grow β an autoflowering feminised plant, because it removes the decision beginners most often get wrong.
- A few seasons in β photoperiod plants such as Girl Scout Cookies, OG Kush, White Widow or Blue Dream, which carry more weight in exchange for managing the timing yourself.
- Experienced β the shelf listed above 25%.
- Outdoor specialists β varieties selected for structure that copes with wind and an open flower that dries rather than holds moisture.
- For the flavour β OG Kush, Bubba Kush, Granddaddy Purple, exotic crosses.
Start With the Seed Type
Get this decision right and most of the others get easier. Feminised seed means nothing to sex and nothing to pull out β every pot earns its space. An autoflower ignores daylight entirely and is done in as little as eight weeks, which matters more the further south you are. A photoperiod plant hands the timing back to you, and with it the size.
Feminised Seeds
1,254 varieties, all female β nothing to sex, nothing to pull out and throw away.
Autoflower Seeds
Ten to twelve weeks start to finish, and the light schedule never changes.
Indica Genetics
Short, wide and quick to finish β the structure that suits a short southern season.
Sativa Genetics
Tall and late, and worth the season length only where you actually have it.
High THC Seeds
The strong end of the catalogue, listed at 25% and above. Assumes a tolerance to match.
CBD Seeds
Bred for a different cannabinoid balance, with THC well below the rest of the catalogue.
Seeds Chosen for Your Part of New Zealand
New Zealand is long and narrow, so climate changes with latitude far more than with distance inland. What works in a humid Northland summer is not what survives an Otago autumn. Pick for your conditions before you pick for potency.
Northland & Auckland
The warmest and longest season in the country, and the most humid. Warm, humid summers give plenty of growing time, but a damp February and March put real pressure on dense flowers. Open bud structure and a fast finish matter more here than raw yield.
Waikato & Bay of Plenty
Warm, fertile and reliably productive, with enough humidity that airflow through the canopy becomes a deciding factor in late flower. Generous season length also makes a second autoflower run practical in a good year.
Gisborne & Hawke's Bay
Among the sunniest and driest parts of the North Island, sheltered from the prevailing westerlies by the ranges. Lower mould pressure than the north or west means longer-flowering cultivars can be taken further without the same risk.
Nelson, Tasman & Marlborough
The highest sunshine hours in the country, with a dry summer and a settled autumn. If there is a forgiving outdoor climate in New Zealand, this is it, and it tolerates a wider range of genetics than anywhere else.
Wellington & Taranaki
Wind is the defining problem rather than temperature. Exposed sites put heavy mechanical load on plants carrying weight late in flower, so shorter, sturdier plants and early training hold up where tall phenotypes do not. Many growers here move indoors for control.
Canterbury, Otago & Southland
Cool, dry east-coast conditions with a genuinely short window. Frost can arrive from April and earlier inland, which rules out anything needing until May. Autoflowers started early, or short-flowering photoperiods, are the practical route this far south.
The Strong End: Listed Above 25%
These carry the highest published figures we hold, and they assume a tolerance to match. Worth noting that potency is largely fixed by genetics but expressed by conditions, so a well-run grow of a mid-range cultivar routinely beats a neglected grow of a headline one.

Not Sure Where to Start? Match Your Goal to a Seed Type
What you are trying to get out of the plant should decide which shelf you start on. Four common aims, and where each one sensibly begins.
Never Done This Before?
An autoflowering feminised plant. It blooms on age alone, mostly stays under a metre, is finished in eight to ten weeks, and absorbs the mistakes a first grow inevitably makes.
Start here βAfter the Heaviest Harvest?
A photoperiod plant vegetated five or six weeks under an 18-hour day, then trained flat across a screen, is what carries the most weight indoors. It asks more of you than an autoflower and takes months rather than weeks, which is the whole trade.
Photoperiod genetics βPlanting Outdoors This Season?
Match the flowering time to your own frost date. The further south you are, the shorter the usable window β and the more an autoflower or a fast photoperiod earns its place.
Explore Outdoor Strains βWant Something Gentler?
CBD-forward lines are bred for a different cannabinoid balance, and the flower is far less intoxicating than the THC-dominant end of the catalogue. A balanced 1:1 sits between the two. What any plant actually expresses moves with phenotype and growing conditions, so treat a published ratio as the intent rather than the result.

Royal King Seeds in New Zealand
This is a seed catalogue assembled for New Zealand conditions, and it is new. Rather than claim a history it does not have, it is more useful to set out what the site does and how it treats the information on it.
Four figures sit on every listing where we could trace them β flowering window, indoor and outdoor yield, and height β each taken from breeder documentation or a published reference rather than estimated. Coverage is close to complete: all 1,677 carry a flowering time and a yield, and exactly one is missing a height. Where something genuinely is not published, the field stays blank rather than being filled with a range that would look plausible and mean nothing.
Filtering follows the order growers actually decide in: whether you want to control the flip or let the plant run on its own clock, how fast it finishes, how much headroom you can give it, then flavour and effect. Prefer to be asked rather than to browse? The strain finder narrows all 1,677 varieties down to a short list.
Everything is priced in New Zealand dollars with GST in the figure and nothing added for paying by card. Parcels leave in plain, unbranded packaging and travel tracked to addresses on either island, rural delivery included.

What Sets Royal King Seeds Apart
Six things this store does, each of them checkable against the site itself rather than asserted about it.
Written on the Right Calendar
Every timing here runs on a Southern Hemisphere year β out after the last spring frost, down through March and April. Most cannabis advice online is Northern and is six months out of step by the time it reaches you.
Traced Figures, or a Blank
Flowering window, yield and height come from breeder documentation or a published reference, recorded against the strain. Nothing gets estimated to fill a gap β an empty field means we could not trace it.
Filters That Match the Decision
Photoperiod or autoflower, how quickly it finishes, how tall it gets, then effect and flavour. Which is the order that matters if you are working under a fixed ceiling or against an April frost.
The Shelf Price Is the Price
New Zealand dollars, GST already in the figure, and no surcharge added for paying by card. What the cart says is what is charged.
Nothing on the Outside
Plain packaging with no logo and no description of the contents, tracked to either island and to rural addresses.
Card or Crypto
Cards are handled by the payment gateway and the full number never touches this site. Bitcoin and other cryptocurrencies work as an alternative.
