What People Ask Us

Feminised seeds produce female plants and flower when the daily dark period passes about twelve hours — indoors you flip the timer, outdoors the shortening autumn light does it for you. Autoflowers ignore daylight and bloom on age, finishing eight to ten weeks from sprout. In New Zealand that difference decides more than it does elsewhere: south of about Taranaki the first frost sets the deadline, not your preference, so an autoflower planted in November finishes while a late photoperiod sativa is still filling out.

An airtight jar in the fridge, kept dark and dry, holds viability for years. The part that catches people out here is humidity rather than temperature: most of New Zealand sits well above the moisture level seeds like, so a silica sachet in the jar earns its place, and taking the jar out to warm to room temperature before opening stops condensation forming on cold seeds.

We guarantee 95% germination and replace anything that falls short — same strain, same pack size, free of charge. Germinate using the method in our guide, then email us within 30 days of your parcel arriving with the order reference and a photo of the attempt. Damp paper towel at room temperature is what we test against; a cold snap in an unheated Southland shed will stall a seed that was perfectly viable, so the photo is there to tell those two cases apart rather than to catch anyone out.

Yes. Our growing guides are 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 advice online is written for the Northern Hemisphere and is six months out of step by the time it reaches you. If you tell us your region and whether you are indoors or out, we will narrow the catalogue for you.

New Zealand summers are rarely hot enough to stress cannabis — humidity is the harder problem. In Northland, Auckland and the Bay of Plenty, where February and March are muggy, prioritise open bud structure and mould resistance over heat tolerance. Sativa-dominant hybrids suit the warm north because the season is long enough to finish them. Further south, through Canterbury, Otago and Southland, dry summers suit almost any variety and the real constraint is finishing before the first frost.

All sixteen regions, both islands — Northland through to Southland, and the West Coast as readily as Auckland. Rural delivery runs a day or two behind the main centres and is the one exception to our stated transit window. Every parcel goes out in plain, unbranded packaging that says nothing about the contents.

We pack and send inside 1-2 business days. From there NZ Post is generally 3-7 business days on the road, quicker into the main centres and slower to a rural address. The tracking number reaches you the moment the label prints, so you can watch it rather than wonder.

Anything from $150 NZD up goes postage-free, applied on its own at checkout. Below that it is a flat $14.99, the same figure whatever the parcel weighs and wherever in the country it is going.

Nothing on the outside says what is inside. Plain satchel, no logo, no product description, no mention of seeds or of Royal King Seeds — the sender line and the courier label are all anyone sees, including whoever signs for it at a rural delivery point or a shared letterbox.

Pick your strains and pack sizes, then check out with a New Zealand delivery address — that is the only country we ship to, so the region list is the sixteen official ones from Northland to Southland. A confirmation email lands straight away, and a tracking reference follows when the parcel leaves us.

Visa and Mastercard, and major cryptocurrencies including Bitcoin and Ethereum where that option is showing at checkout. Prices are charged in New Zealand dollars, so the figure on the product page is the figure you pay — no conversion applied afterwards. Card details move over an encrypted connection and are handled by the payment provider, not stored by us.

Email support@royalkingseeds.co.nz within 2 hours and we will almost always catch it. After that the order has usually been picked and packed, and at that point the honest answer is that a change means waiting for the parcel to arrive and sorting it out from there.

The per-seed price drops as the pack size goes up, so a 10-seed or 20-seed pack costs less per seed than a 3-seed pack of the same strain. Both are listed on every product page. For anything larger than the packs we list, email us and we will quote it.

Stock is supplied to adults as souvenirs and for preserving genetic lines. We take no position on what your own jurisdiction allows, because the rules vary and they change; establishing what applies where you are, and keeping inside it, is yours to do before you order. None of this is legal guidance.

Your details travel over an encrypted connection and are not sold or passed to anyone outside the people who need them to get your parcel to you. Under the Privacy Act 2020 you can ask us for a copy of what we hold and ask us to correct it; our Privacy Policy sets out how, and where to take a complaint if you are not satisfied with our answer.

You must be 18 or over to order, or older if that is the threshold where you live.
