Crown OG Auto
Growing Crown OG Auto in New Zealand: a indica at 20% THC, euphoric, creative, calm. Flowering window and height are on the page where we hold them, blank where we do not.
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 2026-09-15, from a tray sample of 400.
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 Crown OG Auto
Days 1 to 14. Crown OG 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.
Crown OG 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. There is no flip. Flowering starts on its own, which means any stunting from an over-eager early feed is now permanent.
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 Medium.
Harvest. Published window: 55-65 days. 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.
Effect Profile
Euphoric, Creative, Calm is the consensus, and consensus is worth exactly what it sounds like β a starting point. 20% THC sets the scale; myrcene and the terpenes alongside it shape the character rather than the strength.
Onset is quick by inhalation and slow by ingestion, which is where most bad experiences begin. Expect the weight to settle physically within the hour.
If potency is what you are shopping for, the high-THC seeds category is sorted for it.
The Terpenes
Myrcene leads, humulene sits behind it, and linalool runs underneath.
Aroma is not fixed at harvest β it develops. Fresh flower leads hard with myrcene; three or four weeks in sealed glass at a stable 16 to 18 degrees lets humulene and linalool come forward as the sharper volatiles clear. Jars opened at week one and week five smell like different plants.
Who It Suits
Crown OG is rated intermediate. That sits in the middle β you want a working understanding of pH and feeding, but nothing exotic. 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 Crown OG 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.
