California Grapefruit Feminised

Days 1 to 14. California Grapefruit 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 — 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.

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 fairly even growth in both directions.

The transition. After the flip the plant may double. Whatever shape the canopy is at that point is roughly the shape you harvest.

Mid-flower. Bud sites fill and the aroma arrives — 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 50–140 cm.

Harvest. Published window: 8-9 weeks. Trichomes decide. Cut in sections if ripening is uneven — most plants ripen top-down and there is no prize for taking it all at once.

Euphoric, Creative, Calm is the consensus, and consensus is worth exactly what it sounds like — a starting point. 12% 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 a mental lift first, with the body catching up later.

If potency is what you are shopping for, the high-THC seeds category is sorted for it.

Myrcene leads, limonene sits behind it, and pinene runs underneath.

This trio is a common signature in well-regarded cultivars, which is not an accident: myrcene carries weight, limonene adds definition, pinene keeps it from being one-note. It reads clearly on a first opening rather than needing to be hunted for.

California Grapefruit is rated easy. That makes it a reasonable first grow — it survives inconsistent watering and imprecise feeding without collapsing, which is what a first season mostly consists of. Being a photoperiod means you decide when it flowers, and therefore how big it gets.

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