Lineage White Widow Autoflower seeds

White Widow Autoflower, from the cross of White Widow and Ruderalis, is a sativa-leaning autoflowering hybrid (55% Sativa / 45% Indica). It tends to show citrus, earthy, pine and pungent flavors with a bright, sativa-leaning high.

It also carries a High THC of 20% – 25%, making it a great choice for anyone looking for a happy experience with a good dose of energy, well suited to easing fatigue, muscle spasms and stress.

Origin

White Widow Autoflower inherits its potent effects and dense, resinous buds from the iconic White Widow, originally bred in the Netherlands, a testament to its strong European genetics, and later crossed with other varieties such as White LSD Auto.

The autoflowering version shifts from vegetative growth to flowering automatically, without any change in light cycles, which simplifies cultivation and makes it ideal for growers with limited space or those seeking a quick turnaround.

These seeds combine the resilience and easy-growing nature of Ruderalis with the high THC content and mesmerizing trichome coverage of White Widow, allowing cultivation across a wide range of climates.

Despite its short stature and rapid life cycle, Auto White Widow does not compromise on potency or yield. That makes it especially appealing to novice and experienced growers alike, and its robust genetic foundation ensures consistent, reliable performance.

White Widow Autoflower Sativa or Indica?

White Widow Auto is a hybrid that balances both Sativa and Indica characteristics (45% Indica / 55% Sativa). Descending from its iconic parent, it keeps that genetic equilibrium: a touch of Sativa’s energizing lift alongside Indica’s soothing qualities.

The sativa side offers an uplifting cerebral experience, while the indica genetics bring a relaxing body feel that never overwhelms. That harmonious blend makes White Widow Auto a versatile choice, well suited to a range of occasions and preferences for a well-rounded experience.

If you want a strain that combines the best of both worlds, White Widow Auto is a testament to expert genetics and thoughtful cultivation.

White Widow Auto Effects

The effects of White Widow Auto reflect its balanced Sativa and Indica heritage. The onset brings a rush of euphoria and mental clarity from its sativa side, a creative, invigorating state that pairs with the calming physical sensations of its indica genetics.

Consumers often report a happy, talkative mood with a relaxation that spreads through the body. That mix makes White Widow Auto suitable for both daytime and evening use: whether you are after inspiration for creative projects or a way to unwind after a long day, it delivers a well-rounded effect profile that caters to a range of preferences.

Flowering time

White Widow Auto pairs a compelling genetic profile with the benefits of autoflowering genetics, and one of its standout features is a relatively short life cycle: from germination to harvest, it finishes in approximately 8 to 10 weeks.

That swift cycle is the result of expert breeding that optimized the strain for rapid development, which means a more efficient growing process and quicker turnarounds. Whether you are a seasoned grower or just starting out, White Widow Auto lets you cultivate premium cannabis in a short time frame, with genetics honed for both quality and speed.

Grow Info White Widow Autoflower seeds

White Widow Autoflower seeds can be grown indoors or outdoors under optimal conditions, to avoid any problems during their development. Although they are compact, robust and moderately easy to grow, we should always prevent any pests.

You can use different growing methods to retain and enhance the terpenes and flavors of your buds.

• Use a quality substrate. Perlite, peat, or coco coir are ideal for moisture retention.
• Thanks to the experience of our customers with White Widow Auto seeds, we know that we can increase yields by up to 20%.

Autoflowering seeds are very popular among growers. They are known for their fast life cycle and their ability to flower automatically after a set period of time, rather than relying on changes in the light cycle like other cannabis strains. As for light, they can grow and flower with as little as 12 hours per day, and they do not need a specific light change to move from the vegetative to the flowering stage. We recommend an 18/6 or 20/4 schedule to obtain the best possible yields. This gives growers greater control over the process without having to worry about light timing.

Even so, it is important that the plants receive enough light for healthy growth, as the quality and quantity of light affect both yield and development. Another advantage of autoflowering seeds is their fast life cycle: these plants can grow and flower in as little as 8-10 weeks, which means several harvests a year. They also tend to be smaller and more compact, making them ideal for small spaces or indoor grows. As for quality, keep in mind that genetics and growing conditions play a big role.

Many autoflowering strains have won awards for their taste, aroma and effects, proving they can produce high-quality marijuana. Remember that our plants also need good nutrients as seedlings, in their vegetative period and in their flowering period. When growing outdoors, choose the best date for your crop and a place where the plants receive the most hours of sunshine. If you prefer to grow indoors, use good tents, textile pots, LED lighting, an air extractor to circulate clean air and, of course, a good carbon filter to avoid problems with neighbors or the law. Keep daytime temperatures between 68-80 ℉ and nighttime temperatures 7 to 9 ℉ cooler than the day.

White Widow Autoflower plants need low humidity to thrive. Keep relative humidity (RH) at 55%-60% during the vegetative phase, reduce it to around 40% during flowering and to about 30% by harvest.

Outdoors, in the Northern Hemisphere growers should sow their autoflowering seeds in April, achieving a first harvest in mid summer and a second between July and mid October. Healthy White Widow Autoflower seeds produce about 21 oz/plant | 600 gr/plant of buds each.

Indoors, these crops have a life cycle of 8 – 10 weeks and produce about 1.15 – 1.47 oz/ft² | 350 – 450 gr/m².

Best Climate for Growing White Widow Autoflower

White Widow Autoflower thrives in a temperate, continental or Mediterranean climate, with ideal temperatures between 68-80 ℉ (20-27 ℃). It performs best at latitudes between 30° and 50°, which suits both low-altitude coastal regions and moderate elevations. Annual precipitation of 20-40 inches (500-1000 mm) is optimal, and well-draining soil is essential to prevent excess moisture retention.
