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 2026-09-21, from a tray sample of 480.

Opened on the bench: 98.3% of 480
Lot checked: 2026-09-21, at 21-24Β°C
Under lights here: 436-573 g/mΒ², across 12 grower reports
Outside here: 486-761 g/plant, across 10 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 RS11 Feminised

Days 1 to 14. RS11 cracks on damp paper towel inside about two days and is through the medium by day three, given warmth and patience rather than intervention. Seedlings want humidity near 70% and no nutrients at all β€” the seed carries everything for the first week. By the end of the fortnight you are looking for even node spacing rather than height; a stretched seedling is a light problem, not a vigour signal. New to this? The free seeds on offer are a low-stakes way to practise the germination step.

RS11 Through the Grow

Weeks 3 to 6. Growth stops being tentative. This is when training earns its keep: bend rather than cut if you are unsure, because a bent branch recovers in a day and a topped one costs a week. Expect width rather than height, and space plants accordingly.

The transition. After the flip the plant may double. Whatever shape the canopy is at that point is roughly the shape you harvest.

Mid-flower. Bud sites fill and the aroma arrives β€” usually the point where extraction stops being optional. Feed heavier now, but watch the leaf rather than the schedule.

The last fortnight. Ease off nitrogen, drop the night temperature a little, and stop feeding before you think you should. Final height for this cultivar is published at 120 cm.

Harvest. Published window: 63 days (9 weeks). Trichomes decide. Cut in sections if ripening is uneven β€” most plants ripen top-down and there is no prize for taking it all at once.

What RS11 Is Like

Reported effects cluster around uplifted, calm. At 27% THC that is a meaningful figure rather than a decorative one, and the sensible approach with anything in this range is to start lower than you think and wait longer than feels necessary.

The 77/23 balance shapes where it lands: body-forward, better suited to an evening than a task list. Tolerance moves this more than any other variable, which is why two people describe the same jar differently.

Prefer something gentler? The CBD-forward strains range trades peak potency for balance.

The Terpenes

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

Aroma is not fixed at harvest β€” it develops. Fresh flower leads hard with caryophyllene; three or four weeks in sealed glass at a stable 16 to 18 degrees lets myrcene and bisabolol come forward as the sharper volatiles clear. Jars opened at week one and week five smell like different plants.

Who It Suits

Who does well with RS11? 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 RS11 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.
