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 2026-09-23, from a tray sample of 160.
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 Sweet ZZ Auto
Sweet ZZ is bought for what comes off it, and the sourced figures are 350-400 g/m2 under lights and 90-175 g/plant from a plant grown out. Those are ceilings, not promises — 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 Sweet ZZ
What the sourced data gives for this cultivar: 350-400 g/m2 under lights, 90-175 g/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 — 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 — 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 85/15 indica at 20% THC, commonly described as creative, focused, calm, with caryophyllene 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
Caryophyllene leads, myrcene sits behind it, and bisabolol runs underneath.
This trio is a common signature in well-regarded cultivars, which is not an accident: caryophyllene carries weight, myrcene adds definition, bisabolol 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 Sweet ZZ? Growers with limited headroom or no interest in managing timers. Apartment balconies. Anyone wanting more than one run in a season. First-timers included — the genetics are forgiving.
Still deciding? The indoor-friendly genetics list is the narrower place to start.

Where Sweet ZZ Auto Comes From
Documented parentage is Grape Ape × Grapefruit. 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 — 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.
