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 2026-09-04, from a tray sample of 480.

Opened on the bench: 95.6% of 480
Lot checked: 2026-09-04, at 20-23ยฐC
Under lights here: 415-530 g/mยฒ, across 7 grower reports
Outside here: 467-727 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 Electric Blue Feminised

Days 1 to 14. Electric Blue 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 โ€” 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.

Electric Blue 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. 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 โ€” 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 Small (0-120 cm).

Harvest. Published window: 9-10 weeks. Trichomes decide. Cut in sections if ripening is uneven โ€” most plants ripen top-down and there is no prize for taking it all at once.

Effect Profile

Euphoric, Energetic is the consensus, and consensus is worth exactly what it sounds like โ€” a starting point. 18% THC sets the scale; linalool 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

Linalool leads, myrcene sits behind it, and caryophyllene runs underneath.

Temperature changes what you get. Vaporised low, around 180 to 188 degrees, myrcene and caryophyllene come through cleanly while linalool stays in the background. Combusted, linalool dominates and the finer detail is largely lost. Same flower, two different experiences.

Who It Suits

Electric Blue is rated moderate. That sits in the middle โ€” you want a working understanding of pH and feeding, but nothing exotic. 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.

Where Electric Blue Feminised Comes From

We hold no documented parentage for this cultivar, so none is shown. A blank here is an admission rather than an oversight โ€” 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 โ€” 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.
