Fast-flowering cannabis seeds in New Zealand
Fast flowering cannabis seeds answer the question every New Zealand grower asks in February: will it finish before the rain? The strains in this range flower in 7 to 9 weeks — some less — and are chosen to be harvested in March, ahead of the autumn wet that turns dense colas to rot from Northland to Southland. Fast doesn't mean small or weak; this range includes potent, heavy-yielding genetics that simply flip and finish quickly. You'll find fast-version photoperiod strains alongside the quickest autoflowers, with flowering weeks front and centre on every listing. If you've lost a crop to bud rot in April, or you grow in the South Island where the season is short and the nights turn cold early, this is where to start.

How to choose fast flowering seeds
Work out your deadline first: the date your region's autumn rain or first frost typically arrives, minus two weeks for drying. Then pick strains whose flowering weeks, counted from when flowering begins (early to mid-February in most of New Zealand), land before it. In the South Island that usually means 7 to 8 weeks; in the central North Island, 8 to 9; in the far north, the constraint is humidity rather than cold, and 8 weeks with an open structure is the target. Fast-version photoperiod strains give you a full-sized plant and a single early harvest; fast autoflowers give a smaller plant, total control over timing, and the option of a second run. Between two strains that both make your deadline, take the one with the better mould-resistance note.
Growing fast flowering seeds in New Zealand
The strategy is simple: finish before the weather turns. Fast photoperiod strains still need the full vegetative season, so plant them out at Labour Weekend and let them grow; the advantage comes at the end, when they flip in early February and are ready in late March while slower strains are still weeks away and the rain has arrived.
| Region | Typical rain/frost onset | Harvest deadline | Flowering weeks needed |
|---|---|---|---|
| Southland, Central Otago | Early–mid April (frost) | End of March | 7 |
| Canterbury, West Coast | Mid-April | Early April | 7–8 |
| Wellington, Manawatū, Taranaki | Mid–late April | Early April | 8 |
| Waikato, Hawke's Bay, Nelson | Late April | Mid-April | 8–9 |
| Northland, Auckland, BoP | Humidity from Feb; rain from April | Mid-March | 8, with open structure |
Autoflowers in the fast range give southern growers a cleaner option: sow in mid-November for an early-February harvest in peak sun, with no frost or rain risk at all. Don't rush the dry just because you rushed the finish; a fast strain harvested in March still needs 10 to 14 days of slow drying in a room with a dehumidifier, and a proper cure.

Frequently asked questions
What counts as a fast flowering strain?
Photoperiod strains that finish flowering in 7 to 8 weeks are fast; 9 is average; 10 or more is slow. Autoflowers are measured from seed and are fast when they finish in 8 to 9 weeks total.
Are fast strains less potent?
Not in this range. Fast flowering was bred into potent strains by crossing them with early-finishing genetics, and the best modern fast versions lose little or nothing in strength or flavour.
Why does finishing time matter so much in New Zealand?
Because autumn rain and humidity arrive right as dense flowers mature, almost everywhere in the country. Finishing in early March rather than late April is often the difference between a full harvest and a mouldy one.
What's the difference between a fast version and an autoflower?
A fast version is a photoperiod strain bred to flower faster; it still needs shortening days to start and grows to full size. An autoflower flowers on age regardless of daylight and stays compact. Fast versions yield more; autos give more control over timing and cope better with wind.
Can I make a normal strain finish faster?
Slightly. Outdoors you can cover plants for 12 hours a day from January to force early flowering, but it's laborious and stresses the plant. Choosing a genuinely fast strain is far more reliable.
Do fast strains yield less?
A little, per plant, compared with an 11-week strain that finishes in time. Compared with an 11-week strain that rots in April — which is the realistic alternative in most of New Zealand — they yield far more. In practice they're the highest-yielding option in short-season regions. ---
