About Lethal Purple Feminised

Lethal Purple announces itself in a fixed order, and limonene is always first out of the jar — a citrus lift that arrives before the lid is fully off, lemon rind and tangerine with a sweetness trailing it. caryophyllene follows mid-palate, adding a grounding spice. The lab figure on this 38/62 hybrid is 20% THC, though potency is the least interesting thing about it — plenty of cultivars test the same and taste of very little.

Growing for Aroma Rather Than Weight

The choices that bring out the Limonene/Caryophyllene/Linalool profile in Lethal Purple are not the choices that maximise yield, and at some point you have to pick one. The aromatic version starts in living soil — microbial activity in an established no-till bed produces secondary metabolites a synthetic feed schedule never will, and South Africa has enough good local compost and worm-casting suppliers to make that affordable rather than aspirational.

Through 45 – 55 days, stop foliar spraying after week two: anything that lands on a developing trichome is still there at harvest. The closing three weeks decide which terpenes end up in front — nights held at 16-18°C push limonene forward, a warmer finish protects the lighter linalool top notes, and you cannot have both. Decide which version of the strain you want before you get there.

Most of the loss happens after the cut. Hang for 10-14 days at 15-18°C and 55-60% humidity, which through a South African summer realistically means a climate-controlled room or a wine fridge set to 16°C. Then jar it and burp twice daily for the first fortnight. The caryophyllene layer that makes this cultivar worth the trouble does not surface until somewhere between day 21 and day 28 in glass.

Difficulty: intermediate. In flower for 45 – 55 days. Stands Tall. Indoors it returns up to 450 g/m2. Outdoors, up to 450 g/plant a plant.

Aroma, Flavour and Effect

The first thing Lethal Purple does at 20% THC is lift it with a bright, nearly effervescent citrus. The relaxed, happy, euphoric effects follow within minutes, across head and body at once. Thinking stays clear while muscle tension drains off, which leaves the dose as the deciding factor — light for the afternoon, heavier and it moves into the evening without a jolt. Caryophyllene sits underneath all of it, adding a grounding warmth that keeps the whole thing anchored.

The Aromatic Three

Leading with Limonene, then Caryophyllene, and Linalool underneath. How this combination survives the move from flower to vapour or smoke is not a given. Held low, at 180-188°C, the caryophyllene and linalool notes stay legible with limonene underneath them. Run it hotter, or burn it, and the three collapse into one — still pleasant, but without the separation that makes this cultivar worth paying attention to.

Suitability and Recommendations

Who does well with Lethal Purple? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated intermediate, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions. Sent nationwide in plain, unbranded packaging, with sourced grow data on every strain page.

Stabilisation Notes — What This Means for Your Grow

Lethal Purple carries clone-derived parents from the mid-2010s. We backcrossed twice to the dominant parent (BX2) to weld cut-specific traits into seed-stable form. Vigour and finish-time consistency run uniform across the population.

Breeding Goal

Pin the finish-time consistency that came out of the original Lethal Purple cross.

Selection Focus

Chosen for balanced indica/sativa expression, terpene fidelity and pack-to-pack uniformity.
