Grapefruit feminized seeds deliver a sativa-dominant photoperiod strain built around sharp citrus aromatics, an energising effect profile, and a relatively fast flowering window of 55 to 62 days. With THC levels sitting at approximately 20%, this strain punches well above its modest cultivation demands, making it a dependable choice for growers who want quality without complexity.

Genetics & Lineage

Grapefruit traces its ancestry to Cinderella 99 crossed with a tropical sativa landrace. Cinderella 99 contributes the accelerated flowering pace, dense resin production, and that signature sweet-citrus terpene expression. The landrace parent broadens the genetic base, adding stretch, tropical fruit depth, and the sustained cerebral clarity the strain is known for. The resulting ratio lands at roughly 70% sativa / 30% indica — enough indica influence to keep internodal spacing manageable, but sativa-forward in every way that matters to the end experience. All seeds in this pack are feminised, eliminating male plants and allowing growers to maximise every square metre of canopy space.

Aroma, Flavour & Effects

The terpene profile is anchored by Limonene, Myrcene, Caryophyllene, and Pinene. Limonene dominates throughout — it drives the fresh, slightly bitter citrus peel character that defines the aroma at every stage of growth, intensifying sharply in the final two weeks of flower. Myrcene softens the edges with a tropical sweetness that prevents the citrus from reading as harsh. Caryophyllene adds a faint spiced warmth on the exhale, while Pinene brings a clean, resinous lift that keeps the overall profile bright rather than heavy. Research into Limonene suggests the compound may contribute to the mood-elevating, uplifting quality of the effect — and that aligns closely with what this strain produces. Onset is relatively quick, with a clear-headed, sociable energy that supports focus and conversation without inducing anxiety at moderate doses. The 20% THC content means it delivers genuine potency; this is not a strain to underestimate on an empty afternoon.

Growing Profile

Grapefruit feminized performs well both indoors and outdoors. Indoors, growers can expect yields in the range of 450 to 550 grams per square metre under optimised conditions. Outdoors, individual plants in a full-season run can return up to 600 grams per plant depending on climate, container size, and canopy management. The 55 to 62 day flowering window is a meaningful advantage — it reduces the exposure window for late-season issues and suits growers running multiple cycles per year. Height management is worth planning for: the sativa genetics produce moderate stretch during the transition to flower, and low-stress training (LST) or a light topping early in veg will improve light penetration and even out bud development across the canopy. Difficulty level sits at beginner to intermediate — the strain is forgiving of minor feeding fluctuations and does not require precision environmental control to perform well.

Who This Strain Is For

Grapefruit feminized suits daytime consumers who prefer an uplifting, functional effect over sedation. It works well for creative work, social settings, or any situation where clarity and mood elevation are the priority. Growers looking for a high-yielding, fast-finishing sativa with genuine terpene character will find the 55 to 62 day turnaround genuinely useful. First-time cultivators benefit from the strain's structural resilience, while experienced growers can push yields further with ScrOG setups and dialled-in nutrition schedules.

A fast-finishing, high-terpene sativa that holds its own from seed to smoke — Grapefruit feminized is straightforward to grow and difficult to overlook.
