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 2026-09-02, from a tray sample of 400.

Opened on the bench: 98.2% of 400
Lot checked: 2026-09-02, at 20-23Β°C
Under lights here: 423-525 g/mΒ², across 13 grower reports
Outside here: 407-709 g/plant, across 3 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 Ace of Spades Auto

Ace of Spades is bought for what comes off it, and the sourced figures are 600 g/mΒ² under lights and 500 g per plant from a plant grown out. Those are ceilings, not promises β€” pot volume, light intensity and how honestly you feed decide where you land inside them. Run the numbers for your own tent with the yield calculator before committing to a pack size, and put it next to the rest of the high-yield strains if weight is the whole point.

Getting the Weight Out of Ace of Spades

What the sourced data gives for this cultivar: 600 g/mΒ² under lights, 500 g per plant from a plant grown outside. Reaching either is an environment problem before it is a genetics one.

Root volume sets the ceiling before a single flower forms. Under-pot a plant and no feeding schedule rescues it. Get the container right early and the plant does the rest.

Light is the second lever, and the one most growers get wrong in both directions β€” too little through veg, too much in late flower where it bleaches rather than builds. Steady beats aggressive.

The third is the fortnight around the flip. Autoflowers give you no flip to manage, which is exactly why the vegetative period has to be right the first time β€” there is no second chance to fix a stunted start.

Feed to the plant rather than the calendar. Our nutrient calculator gives a starting schedule; the plant will tell you where it is wrong. Worth a side-by-side comparison before you commit if weight is the deciding factor.

Reading the Effects Honestly

Effect descriptions are the least reliable part of any seed listing, this one included. What is defensible: this is a 66/34 indica at 20% THC, commonly described as relaxed, sleepy, happy, with linalool leading the terpene profile.

What is not defensible is any promise about how it will feel for you. Dose, tolerance, setting and the phenotype you happen to pop all move the outcome more than the strain name does.

Growing a few and selecting the keeper is the only way to know. That is what a pack of autoflowering seeds is for.

The Terpenes

Linalool leads, myrcene sits behind it, and caryophyllene runs underneath.

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

Who It Suits

Ace of Spades is rated beginner friendly. That makes it a reasonable first grow β€” it survives inconsistent watering and imprecise feeding without collapsing, which is what a first season mostly consists of. Being an autoflower removes light-cycle management entirely, which suits balcony growers and anyone wanting a fast turnaround.

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

Where Ace of Spades Auto Comes From

Documented parentage is Black Cherry Soda Γ— Jack the Ripper. 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.
