Critical Purple Auto
Critical Purple Auto, a indica listed at 27% THC and described as relaxed, sleepy, happy. Posted unbranded and tracked to any New Zealand address, with the grow figures we could trace on the listing.
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 2026-09-14, from a tray sample of 420.
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 Critical Purple Auto
Latitude decides more about a Critical Purple crop than anything you buy. New Zealand runs roughly 34 to 47 degrees south, and that span turns one 70/30 indica 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 Critical Purple 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. Tight indica flower structure is the risk factor to manage, and it is manageable.
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 49 to 56 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 70/30 indica at 27% THC, commonly described as relaxed, sleepy, happy, with myrcene 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
Myrcene leads, humulene sits behind it, and linalool runs underneath.
Temperature changes what you get. Vaporised low, around 180 to 188 degrees, humulene 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
Critical Purple is rated easy. 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 Critical Purple 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.
