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 2026-09-07, from a tray sample of 360.

Opened on the bench: 97.1% of 360
Lot checked: 2026-09-07, at 21-24Β°C
Under lights here: 349-451 g/mΒ², across 18 grower reports
Outside here: 571-850 g/plant, across 7 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 East Coast Sour Diesel Feminised

Crack a properly cured jar of East Coast Sour Diesel and limonene arrives first β€” that is the compound doing most of the aromatic work here, carried by pinene and rounded off with terpinolene. Terpene expression is not fixed at the genetic level; it is something you either preserve or destroy in the last fortnight and the dry. This page is about keeping it.

Protecting the Limonene in East Coast Sour Diesel

Terpenes are volatile. That single fact explains almost every flavour disappointment growers report.

Late flower. Heat drives off the lighter aromatic compounds, so the last fortnight wants cooler nights rather than a push for size. Growers chasing the final few grams routinely trade away the thing that made the strain worth growing.

The dry. This is where most of the loss happens. Slow and cool, over a couple of weeks, in the dark, with air moving but never blowing on the flower. Fast drying strips limonene first, and it does not come back.

The cure. Sealed glass, opened daily at first, held somewhere stable. Pinene and Terpinolene tend to surface over the following month as the harsher volatiles clear.

Everything above matters more than any bottled additive claiming to boost flavour. If aroma is your priority, the sativa seeds range is where to browse the rest.

Reading the Effects Honestly

Effect descriptions are the least reliable part of any seed listing, this one included. What is defensible: this is a 24/76 sativa at 21% THC, commonly described as euphoric, creative, energetic, 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 feminised seeds is for.

The Terpenes

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

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

Who It Suits

Who does well with East Coast Sour Diesel? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. Anyone past their first grow.

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

Where East Coast Sour Diesel 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 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.
