Strain Overview

Ultra Lemon Haze AUTO seeds by Auto Seeds offer a bold fusion of classic citrus flavor and vigorous sativa-dominant growth in a reliable autoflowering format. Created by crossing the award-winning Lemon Haze with a potent California Sour Diesel and stabilized with Auto Seeds' own Auto #1, this feminized autoflowering strain delivers rich flavor, strong aroma, and exceptional garden performance. Ultra Lemon Haze AUTO seeds are designed for growers who value distinctive terpene profiles and vigorous plants with a compact yet productive growth pattern.

Genetic Lineage and Growth Traits

Ultra Lemon Haze AUTO seeds inherit their sativa dominance from their Lemon Haze and Sour Diesel lineage, resulting in tall, slender plants with long internodal spacing and narrow-fingered fan leaves. Despite its mostly sativa makeup, this autoflowering strain maintains a compact structure indoors, typically reaching heights between 60 and 140 centimeters depending on environment and grow style. Outdoors, under ideal conditions, certain phenotypes can stretch beyond the norm, showcasing their full genetic potential. Flowering time is typically 65 to 70 days from seed, offering a balanced schedule for those seeking efficiency without sacrificing quality.

Cultivation and Yield

Ultra Lemon Haze AUTO seeds are suitable for both indoor and outdoor cultivation. Indoors, this strain thrives in controlled environments where light intensity and airflow can be optimized. With proper care and nutrient scheduling, yields of 400 to 500 grams per square meter are achievable. The plants benefit from a switch to flowering nutrients around week five or six to help boost bud development. Outdoors, the strain performs best when planted between early March and early July, allowing ample time for its full flowering period to unfold. Its resilient genetics make it a practical option for growers in various climates.

Flavor and Aroma Profile

The most striking feature of Ultra Lemon Haze AUTO seeds is the vibrant terpene profile. From early flowering, the plants begin to emit strong citrus scents that become increasingly pronounced as buds mature. The flavor and aroma offer a sharp burst of lemon and pink grapefruit, rounded out by the signature diesel notes of its Sour Diesel parent. This combination creates a layered experience on both the nose and palate, with sweet and sour citrus tones harmonizing with subtle earthy fuel-like undertones. The smoke is smooth, tangy, and lingering, making this strain a favorite among those who prioritize taste.

Bag Appeal and Visual Characteristics

Visually, Ultra Lemon Haze AUTO plants display long, dense sativa-style buds with a generous coating of trichomes and bright orange pistils woven throughout. The foliage is light green with narrow leaves, reflecting its sativa heritage. Buds are spear-shaped and firm, developing more density as they approach harvest. The trichome coverage becomes increasingly prominent in the later stages of flowering, giving the buds a frosty finish that enhances their shelf appeal. When properly dried and cured, the cured flower retains its strong citrus-forward aroma and delivers a visually appealing and aromatic product.

Growing Environment and Seed Type

Ultra Lemon Haze AUTO seeds are feminized autoflowering seeds that simplify the growing process by eliminating the need for photoperiod control or plant sexing. Their flexible structure allows them to perform well in tents, greenhouses, and outdoor gardens alike. While they can reach notable heights under optimal conditions, they remain manageable and highly productive, even in smaller setups. Their resilience, combined with a unique and pungent flavor profile, makes Ultra Lemon Haze AUTO seeds an excellent choice for cultivators seeking standout aroma and a dependable growth cycle.
