Information of White Widow XL Automatic Strain

The White Widow XL Automatic Strain stands out as a reliable and productive version of a legendary cannabis classic. It retains the famous dense frost and earthy, spicy aromas of the original White Widow, while adding the convenience of an autoflowering trait. This makes it an ideal option for cultivators who want fast, predictable results without compromising on flower quality. When you source these seeds from Marijuanaseeds.com, you are guaranteed robust genetics that perform beautifully in various environments. It is highly valued for its impressive resin production and steady growth patterns.

Strain Parents

This unique plant is the result of crossing a potent White Widow XL with a resilient Ruderalis. The White Widow XL parent passes down its signature thick resin production, earthy aroma, and balanced effects. Meanwhile, the Ruderalis genetics introduce the autoflowering capability and compact structure. Together, they create a fast-growing, durable plant that flowers automatically while maintaining the legendary qualities of its lineage.

CBD and THC Content

Consumers can expect a moderate to high THC percentage ranging from 16% to 20%. The CBD content remains very low, typically resting between 0.1% and 0.5%. This specific cannabinoid ratio provides a potent and noticeable experience without being overwhelmingly intense for most users. It delivers a balanced and enjoyable effect that highlights the famous White Widow lineage.

Strain Genetics

Featuring a true 50% sativa and 50% indica genetic profile, this hybrid strain offers the best of both worlds. The indica influence ensures sturdy, thick branches and dense flower formation. The sativa heritage contributes to slightly wider internodal spacing, which helps improve airflow around the buds. This even split results in a highly adaptable plant that grows predictably in diverse environments.

Strain Effects

Users often report a fast-acting wave of mental clarity and uplifted mood that naturally transitions into full-body relaxation. The effects are deeply calming but rarely lead to heavy sedation. A rich terpene profile featuring pinene and myrcene creates an earthy, woody aroma that enhances the overall experience. It provides a steady, enjoyable high that remains manageable throughout the duration.

Climate

This hardy plant thrives in mild to warm climates, preferring daytime temperatures between 70°F and 80°F. For indoor growing, maintaining relative humidity around 40% to 50% during the flowering phase is ideal to prevent moisture issues. During outdoor cultivation, its resilient nature allows it to handle slight temperature drops, making it a reliable choice for cultivators in temperate regions.

Height

Because of its autoflowering genetics, this plant maintains a very manageable size. Indoor plants typically reach an indoor height of 2 to 3 feet. When grown outside, they max out at a modest outdoor height of 3 to 4 feet. This compact stature makes it perfect for discreet gardens. Gentle low-stress training can help maximize light exposure without stressing the fast-growing branches.

Flowering & Harvest Time

The entire life cycle of this autoflower is exceptionally fast. The flowering period begins automatically, allowing harvest within 8 to 10 weeks from the day the seed sprouts. To determine exact harvest readiness, growers should observe the trichomes on the buds. When these tiny crystals turn from clear to cloudy or amber, the plant has reached its peak maturity.

Yield

Despite its small size, this plant delivers a highly satisfying cannabis yield. Indoor growers can expect to harvest between 400 and 500 grams per square meter when using powerful grow lights. Outdoor cultivators typically see yields ranging from 100 to 150 grams per plant. Providing a light, well-aerated soil mix and maintaining consistent watering will help maximize your final harvest weight.
