OG #18 Feminised

Crack a properly cured jar of OG #18 and terpinolene arrives first — that is the compound doing most of the aromatic work here, carried by limonene and rounded off with ocimene. 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.

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 terpinolene first, and it does not come back.

The cure. Sealed glass, opened daily at first, held somewhere stable. Limonene and Ocimene 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.

Reported effects cluster around happy, energetic, creative. At 20% THC that is a meaningful figure rather than a decorative one, and the sensible approach with anything in this range is to start lower than you think and wait longer than feels necessary.

The 22/78 balance shapes where it lands: head-forward and clear enough for daytime, though the ceiling arrives faster than beginners expect. Tolerance moves this more than any other variable, which is why two people describe the same jar differently.

Prefer something gentler? The CBD-forward strains range trades peak potency for balance.

Terpinolene leads, limonene sits behind it, and ocimene runs underneath.

Aroma is not fixed at harvest — it develops. Fresh flower leads hard with terpinolene; three or four weeks in sealed glass at a stable 16 to 18 degrees lets limonene and ocimene come forward as the sharper volatiles clear. Jars opened at week one and week five smell like different plants.

OG #18 is rated intermediate. That sits in the middle — 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.
