The shortest version: Royal Queen Seeds's take on hybrid genetics, 10-14% THC, 7-8 weeks total flowering, easy grow.

The lab panel on this one sits in a modest but useful range — 10–14% THC alongside 3–8% CBD — which makes it one of the few autoflowers worth considering if you want something that won't flatten you on a Tuesday afternoon. White Widow crossed with ruderalis keeps the classic earthy, pine character intact while trimming the timeline down to around 7–8 weeks from seed to harvest, no light schedule required. Indoors you're looking at 400–450 g/m², and because the genetics are forgiving, beginners running their first tent don't need to stress over dialling in a perfect environment. It handles both indoor and outdoor grows without much fuss, which matters if you're in a shorter-season part of Canada and need a strain that finishes before the weather turns.

A solid pick for new growers or anyone microdosing who still wants recognizable White Widow flavour without a steep learning curve.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day.

With THC levels reaching 14%, this provides a mild, approachable experience great for beginners or those seeking gentle relief.

THC Level & Potency

White Widow Auto delivers THC levels of 10-14%, placing it in the milder range, making it approachable for newer users or those seeking functional effects. With CBD levels reaching 3-8%, this strain offers a more balanced cannabinoid profile that may temper the intensity of the THC. The onset typically arrives within minutes with a balanced head-and-body experience that evolves over time.

Growing White Widow Auto

White Widow 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 7-8 weeks total with yields of 400-450g/m². Plants typically reach 40-80cm 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

White Widow Auto features a earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sharp forest and resin notes create a fresh, invigorating flavor with earthy depth. 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, White Widow 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 White Widow 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.
