Spec sheet first — strain: hybrid, seed type: autoflower, THC: 18%, yield band: medium, environment: indoor or outdoor.

Coastal Genetics lists this at $29.93 — below the median of $39.83 across 3 listings. Pack options: 3-seed at $29.93, 5-seed at $44.99, plus larger sizes.

Smell-first, this one announces itself early — a sharp citrus pop that settles into something earthier and sweeter as the grow room warms up. Lemon Auto from Coastal Genetics runs 7–9 weeks from sprout to harvest, which means even a grower who started late in the season can still pull a full run. Yields sit around 350g/m² under decent light, and at 18% THC the effect is uplifting without being overwhelming — functional daytime territory for most people.

The 60/40 indica-leaning ratio keeps plants manageable in height, and the easy difficulty rating isn't marketing fluff — this strain genuinely forgives minor watering inconsistencies and temperature swings that would stress more demanding cultivars. It handles both indoor and outdoor setups without asking for much in return.

Good pick for newer growers who want a fast, citrus-forward autoflower that doesn't require dialing in a complicated feed schedule.

Genetics & Lineage

Lemon Auto traces its genetics to 60% Indica/40% Sativa (Coastal Genetics). This hybrid-dominant autoflower seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Coastal Genetics, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 18%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Lemon Auto delivers THC levels of 18%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing Lemon Auto

Lemon Auto is rated as easy difficulty, making it an excellent choice for first-time growers. The plants are resilient, forgiving of common mistakes like overwatering or inconsistent feeding schedules.

Indoor Growing: Expect a flowering time of 7-9 weeks with yields of 350g/m2. Plants typically reach 100-160cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Lemon Auto features a citrus, earthy, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Lemon Auto is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow Lemon Auto?

This strain is ideal for beginner growers looking for a reliable, low-maintenance plant that delivers consistent results without advanced techniques. If you're looking for evening relaxation and deep stress relief, this is your strain.
