Lemon Royale

Breeder: Swamp Boys Seeds

A sativa-dominant hybrid (70/30) bred by Swamp Boys Seeds that crosses Lemon Tree with their proprietary GMO/TK Skunk male. Known for producing dense, lumpy buds blanketed in trichomes so thick they appear almost white. The terpene profile delivers bold citrus lemon up front with gassy, savory garlic undertones inherited from the GMO parentage.

A sativa-leaning hybrid from Swamp Boys Seeds that merges the sharp citrus punch of Lemon Tree with the funky garlic-gas backbone of GMO/TK Skunk. Plants produce dense, trichome-encrusted buds with a pungent lemon-fuel nose that fills a room. Effects hit fast with cerebral euphoria and creative energy, making it ideal for daytime productivity sessions.

Flowering & Harvest Flowers in 8–9 weeks (56–63 days). Outdoor harvest window targets mid-October in the Northern Hemisphere. Plants show predominantly sativa structure with moderate stretch during early flower.

Plant Structure & Training Reaches 5–8 feet if untopped. The sativa stretch responds extremely well to topping, super cropping, and LST. SCROG and SOG setups maximize canopy coverage and light penetration through the dense foliage.

Environment & Climate Thrives indoors under LED at 800–1000 µmol/m²/s during flower. Prefers daytime temps of 70–80°F and nighttime 65–75°F. Outdoors, needs a warm climate with good airflow. Humidity should stay 40–50% in veg and drop to 30–40% during flower to prevent mold in those dense buds.

Soil & Nutrition Prefers well-draining soil with pH 6.2–6.5. Adding perlite or coco coir improves oxygenation and root health. Responds well to high-nitrogen feeds in veg, transitioning to phosphorus and potassium dominant nutrients in flower. Organic inputs enhance the already loud terpene expression.

Yield Expectations Moderate to high yields depending on training and environment. Indoor growers report up to 400 g/m² with proper SCROG technique. Outdoor plants can produce 280–425 grams per plant under optimal conditions.

Terpene & Aroma Notes Limonene-dominant profile gives the namesake sharp lemon punch. Caryophyllene adds peppery spice, myrcene contributes earthy depth, and trace terpinolene rounds it out. The GMO parent brings a distinctive garlic-fuel undertone that becomes more pronounced as buds cure.

Effects & Medical Use Onset is near-immediate with a rushing cerebral euphoria and heightened focus. No couchlock — purely functional energy for the first 60–90 minutes before tapering into gentle relaxation. Medical patients favor it for depression, chronic fatigue, ADD/ADHD, stress, and migraines. THC tests consistently in the 23–29% range.

Grower Tips Consider the heavy trichome production when choosing trimming method — dry trimming preserves more terps on this strain. The dense bud structure means good airflow and defoliation are critical in mid-flower. Clone-only availability from the original breeder means sourcing verified cuts is important for genetic authenticity.
