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 2026-09-03, from a tray sample of 240.

Opened on the bench: 98.0% of 240
Lot checked: 2026-09-03, at 20-23Β°C
Under lights here: 435-566 g/mΒ², across 17 grower reports
Outside here: 566-850 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 Sister Glue Feminised

Latitude decides more about a Sister Glue crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 47/53 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 Sister Glue 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

Happy, Euphoric is the consensus, and consensus is worth exactly what it sounds like β€” 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, myrcene sits behind it, and humulene runs underneath.

This trio is a common signature in well-regarded cultivars, which is not an accident: caryophyllene carries weight, myrcene adds definition, humulene keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.

Who It Suits

Sister Glue is rated medium. That sits in the middle β€” you want a working understanding of pH and feeding, but nothing exotic. Being a photoperiod means you decide when it flowers, and therefore how big it gets.

Shipped nationwide in plain packaging. Every strain page carries whatever grow data we could actually source, and nothing we could not.

Where Sister Glue Feminised Comes From

Documented parentage is Chem's Sister Γ— Sour Dubble Γ— Chocolate Diesel. 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 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.
