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 2026-09-11, from a tray sample of 140.

Opened on the bench: 96.1% of 140
Lot checked: 2026-09-11, at 21-24Β°C
Under lights here: 468-576 g/mΒ², across 16 grower reports
Outside here: 406-571 g/plant, across 7 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 Black Water Purple OG Cheese Feminised

Will Black Water Purple OG Cheese finish outdoors in New Zealand? In most of the country, yes. The outdoor window runs October to April, and a photoperiod finishes as the autumn light shortens, so the question is whether your first frost arrives before it does. Indica structure copes better with a short season, so the honest answer depends on where you are. The regional notes below are the short version.

Questions New Zealand Growers Ask About Black Water Purple OG Cheese

What medium suits it? Living soil rewards flavour, coco rewards control and speed. Neither is wrong. Choose the one you will actually maintain.

How much light? More in veg than growers expect, less in late flower than they think. Twelve hours of uninterrupted dark triggers flowering β€” and uninterrupted means exactly that.

When is it ready? Trichome colour, not the calendar. The published window is 8-10 weeks, which is a reasonable figure to plan around, but the plant decides.

Is it beginner-friendly? It is rated beginner. That means it tolerates the mistakes everyone makes in their first season.

Where do I put it? Indoors it is predictable; the indoor-friendly genetics list covers what performs in a tent. Outdoors, see the regional notes above β€” or the outdoor-season range if the season is your constraint.

How does it arrive? Plain, unbranded packaging with tracking β€” the detail is on the shipping page.

Effect Profile

Euphoric, Calm is the consensus, and consensus is worth exactly what it sounds like β€” a starting point. 18% THC sets the scale; myrcene 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 the weight to settle physically within the hour.

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

The Terpenes

Myrcene leads, caryophyllene sits behind it, and linalool runs underneath.

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

Who It Suits

Who does well with Black Water Purple OG Cheese? 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 Black Water Purple OG Cheese 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.
