Hempstar delivers the speed and vigor of modern autoflower seeds breeding without sacrificing potency—a rare feat in the auto category. This sativa-leaning hybrid from Growers Lab Seeds stacks 22% THC into a compact 100-160cm frame, finishing in 7-9 weeks while yielding a solid 400g/m². The effects swing between euphoric and focused with underlying relaxation, making it versatile for daytime or evening use. Earthy, skunky flavors ground the high without pretense. Beginners and veterans alike appreciate the straightforward grow—minimal fussing, maximum results—though experienced cultivators comparing this to the breeder's other genetics like Shishkaberry will notice the auto's speed advantage. Built for real-world gardens where reliability matters more than hype.

Genetics & Lineage

Hempstar Auto traces its genetics to Proprietary cross (Growers Lab Seeds). This sativa-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 Growers Lab Seeds, 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 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Hempstar Auto delivers THC levels of 22%, 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, starting as a cerebral buzz that gradually expands.

Growing Hempstar Auto

Hempstar 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 400g/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

Hempstar Auto features a earthy, skunky terpene profile that develops complexity throughout the flowering cycle. The complex aromatic bouquet develops fully after proper curing. 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, Hempstar 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 Hempstar 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.
