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 2026-09-19, from a tray sample of 220.

Opened on the bench: 97.3% of 220
Lot checked: 2026-09-19, at 21-24Β°C
Under lights here: 409-523 g/mΒ², across 10 grower reports
Outside here: 523-772 g/plant, across 4 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 Sweet Diesel Auto

Latitude decides more about a Sweet Diesel crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 14/86 sativa 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 Sweet Diesel 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 55-65 days is the number that matters, because everything is a race against the first frost. An autoflower sidesteps this by finishing on its own clock. If your season is short, the autoflowering indica list is the better starting point.

Reading the Effects Honestly

Effect descriptions are the least reliable part of any seed listing, this one included. What is defensible: this is a 14/86 sativa at 20% THC, commonly described as happy, energetic, creative, with limonene 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

Limonene leads, pinene sits behind it, and terpinolene runs underneath.

Aroma is not fixed at harvest β€” it develops. Fresh flower leads hard with limonene; three or four weeks in sealed glass at a stable 16 to 18 degrees lets pinene and terpinolene 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 Sweet Diesel? Growers with limited headroom or no interest in managing timers. Apartment balconies. Anyone wanting more than one run in a season. First-timers included β€” the genetics are forgiving.

Still deciding? The indoor-friendly genetics list is the narrower place to start.

Where Sweet Diesel Auto 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.
