It is rarely found on dispensary shelves today in its pure form, but it is famous for being the genetic backbone of DNA Genetics' Sleestack. It is prized by breeders for possessing a unique "Fuel Haze" terpene profile and massive yield potential.
THC Content: 18% – 22% (Energetic & Hazy)
Dominant Terpenes: Limonene, Pinene, Myrcene, Caryophyllene
Key Effects: Electric Focus, Clear-Headed Energy, Visual Enhancement, "Daytime" Motivation
In the underground history of cannabis, certain cuts become myths. Shrom is one of them.
Emerging from the United States before the Green Rush, Shrom is believed to be a cross of the heavy-hitting, piney Romulan and the legendary Colombian Gold landrace Sativa. This combination created a biological anomaly: a plant that grew with the ferocity and height of a Sativa but produced dense, fuel-soaked buds that hit with the power of an Indica.
It is best known today as the mother of Sleestack. DNA Genetics recognized Shrom's elite traits—specifically its piercing diesel aroma and high resin count—and used it to create their hash-making champion. To smoke Shrom is to experience the raw, unrefined gas that defined the top-shelf market before "Dessert Weed" took over.
History and Lineage: The Clash of Eras
Shrom represents a bridge between the old world (Landraces) and the new world (Poly-hybrids).
The Mother (Romulan): A North American legend. Often associated with Canada and the PNW, Romulan is a stout, heavy Indica known for its piney, earthy aroma and narcotic effects. It provides the density and the "punch."
The Father (Colombian Gold): The classic Santa Marta Gold. A pure Sativa landrace from the 70s known for its soaring, psychedelic high and lemon/skunk flavor. It provides the structure, the vigor, and the electric mental effects.
The Synthesis: Shrom captures the best of both. It takes the "Gold" high—that clear, zippy energy—and grounds it with the Romulan's body, creating a hybrid that feels like a high-powered Haze but tastes like a pine forest dipped in gasoline.
Terpene Profile: Lemon Fuel and Pine
Shrom has a "loud" profile. It cuts through the air with a sharp, chemical astringency that is highly sought after by old-school smokers.
Dominant Terpenes
Limonene (The Solvent): The dominant note. However, it isn't sweet like candy; it smells like industrial lemon cleaner and citrus rind.
Pinene (The Forest): Inherited from the Romulan. It provides a sharp pine sap and turpentine aroma that clears the sinuses.
Caryophyllene (The Gas): Adds a spicy, diesel-fume kick that gives the strain its "Fuel" reputation.
Flavor Notes:
The Aroma: It is piercing. It smells of spilled gasoline, lemon zest, pine needles, and varnish.
The Smoke: Crisp and expansive. It tastes of sour lime, chemical fuel, and spicy cedar. It has a "bite" to it that lets you know it is potent.
Strain Effects: The Electric Haze
Shrom is a functional smoker's dream. It provides high energy without the paranoia often associated with pure Hazes.
The Experience
The Ignition: The high hits instantly. It feels like a "waking up" sensation. Vision becomes sharper, and colors appear more vibrant.
The Focus: It is an incredible work strain. It allows you to lock into tasks—whether cleaning the house or writing code—with a single-minded focus.
The Body: The Romulan genetics provide a subtle grounding effect. You don't feel jittery or shaky; you just feel "on."
The Duration: It has long legs. The energetic buzz can last for 3+ hours, tapering off into a gentle relaxation rather than a hard crash.
Best For: Wake-and-bake, outdoor activities (hiking/biking), complex problem solving, and combating fatigue or depression.
Growing Shrom: The Stretchy Giant
If you are lucky enough to hold this cut, be prepared: she wants to take over your room.
Growth Structure
The Height: It is Tall. The Colombian Gold genetics make this plant stretch significantly (2x to 3x) in flower. You must top it early and often.
The Yield: High. It produces long, spear-shaped colas that run the length of the branches.
The Feed: It is a hungry plant. It can handle high EC levels and loves Nitrogen in the vegetative stage to support its rapid growth.
The Support: Trellising is mandatory. The branches can become heavy with bud and will snap under their own weight if not supported.
The Time: It finishes relatively fast for a Sativa hybrid, usually in 9 to 10 weeks.
Grower’s Tip: Shrom is a clone-only variety, so you won't find seeds of "pure" Shrom (unless they are S1s). If you grow her crosses (like Sleestack), look for the phenos that stretch the most and smell like lemon fuel—those are the Shrom-dominant keepers.
Final Verdict: The Cult Classic
Shrom is a reminder of a specific era in American cannabis cultivation—a time when "Gas" and "Haze" were the gold standard. It offers a terpene profile that is aggressive and medicinal, and a high that is pure, clean energy. While it may be hard to find in its original form, its genetic legacy as the mother of Sleestack ensures that its resin-producing power and electric high will never be lost.
You should choose Shrom (or Shrom crosses) if:
You love "Fuel/Haze" flavors.
You need high energy and focus.
You are a grower looking for massive yields.
You appreciate rare, clone-only genetics.
