Grapefruit Feminised for New Zealand growers. Sativa, listed 21% THC, energetic, happy, uplifted. Free postage over $150, flat $14.99 below it, both islands.
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 2026-09-12, from a tray sample of 120.
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 Grapefruit Feminised
Latitude decides more about a Grapefruit crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 30/70 sativa 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 Grapefruit in New Zealand Conditions
Indoors the outside world stops mattering and the job is control. Outdoors it is the whole brief.
Upper North Island β 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, ManawatΕ« 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 β 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
Energetic, Happy, Uplifted is the consensus, and consensus is worth exactly what it sounds like β a starting point. 21% THC sets the scale; pinene 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 a mental lift first, with the body catching up later.
If potency is what you are shopping for, the high-THC seeds category is sorted for it.
The Terpenes
Pinene leads, limonene sits behind it, and caryophyllene runs underneath.
This trio is a common signature in well-regarded cultivars, which is not an accident: pinene carries weight, limonene adds definition, caryophyllene keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.
Who It Suits
Who does well with Grapefruit? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. First-timers included β the genetics are forgiving.
Still deciding? The indoor-friendly genetics list is the narrower place to start.

Where Grapefruit Feminised Comes From
We hold no documented parentage for this cultivar, so none is shown. A blank here is an admission rather than an oversight β we would rather leave it empty than publish a lineage we cannot stand behind.
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 β 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.
