Romulan Haze Feminised
Indica genetics for a New Zealand grow. Romulan Haze Feminised carries a listed 19% THC and reads relaxed, sleepy, happy. Priced in NZD, GST included, delivered nationwide.
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 2026-09-03, from a tray sample of 460.
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 Romulan Haze Feminised
Crack a properly cured jar of Romulan Haze and caryophyllene arrives first β that is the compound doing most of the aromatic work here, carried by myrcene and rounded off with bisabolol. 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 Caryophyllene in Romulan Haze
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 caryophyllene first, and it does not come back.
The cure. Sealed glass, opened daily at first, held somewhere stable. Myrcene and Bisabolol 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 indica 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 68/32 indica at 19% THC, commonly described as relaxed, sleepy, happy, with caryophyllene 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
Caryophyllene leads, myrcene sits behind it, and bisabolol runs underneath.
Temperature changes what you get. Vaporised low, around 180 to 188 degrees, myrcene and bisabolol come through cleanly while caryophyllene stays in the background. Combusted, caryophyllene dominates and the finer detail is largely lost. Same flower, two different experiences.
Who It Suits
Who does well with Romulan Haze? Growers who want to control plant size and harvest date, and have the vegetative space to use that control. Anyone past their first grow.

Where Romulan Haze 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.
