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 2026-09-17, from a tray sample of 380.

Opened on the bench: 97.3% of 380
Lot checked: 2026-09-17, at 21-24°C
Under lights here: 420-523 g/m², across 14 grower reports
Outside here: 489-654 g/plant, across 9 grower reports

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 Pandora’s Box Feminised

Latitude decides more about a Pandora’s Box crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 60/40 hybrid into two different plants: a Kaitaia grower fights airflow and humidity through a muggy February, while a Southland grower is counting the weeks to first frost. Neither problem is about heat. If frost rather than heat is your limit, the strain finder sorts the catalogue by finishing time.

Growing Pandora’s Box in New Zealand Conditions

Indoors the outside world stops mattering and the job is control. Outdoors it is the whole brief.

Upper North Island — Northland, Auckland, Waikato, Bay of Plenty. The longest season in the country and the wettest finish. Bud rot, not sunshine, is what costs you a crop here, so plant where morning air moves and thin the interior early rather than admiring a dense canopy in January. More open flower architecture is an advantage through a humid autumn.

Lower North Island. Hawke's Bay and Gisborne are the driest and sunniest stretch; Taranaki, Manawatū and Wellington trade that for rain and wind. Wind decides how tall you let a plant get more than the genetics do.

South Island. Nelson, Tasman and Marlborough offer the best outdoor conditions nationally — high sunshine hours, low summer rainfall. Canterbury, Otago and Southland run a genuinely short season where flowering runs 8-9 weeks is the number that matters, because everything is a race against the first frost. A greenhouse or polytunnel buys the fortnight that makes the difference. If your season is short, the outdoor-season list is the better starting point.

Effect Profile

Euphoric, Calm is the consensus, and consensus is worth exactly what it sounds like — a starting point. 21% THC sets the scale; caryophyllene 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 either, depending on how much you take.

If potency is what you are shopping for, the high-THC seeds category is sorted for it.

The Terpenes

Caryophyllene leads, limonene sits behind it, and myrcene runs underneath.

Temperature changes what you get. Vaporised low, around 180 to 188 degrees, limonene and myrcene come through cleanly while caryophyllene stays in the background. Combusted, caryophyllene dominates and the finer detail is largely lost. Same flower, two different experiences.

Who It Suits

Who does well with Pandora’s Box? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. First-timers included — the genetics are forgiving.

Still deciding? The indoor-friendly genetics list is the narrower place to start.

Where Pandora’s Box Feminised Comes From

Documented parentage is Jack the Ripper × Space Queen. 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.
