What is Hempstar?
Hempstar is a classic Sativa-dominant hybrid born from a three-way cross of Jack Herer, Four-Way, and Skunk #1. With THC in the 14-18% range, Hempstar prioritizes terpene complexity and psychoactive longevity over raw potency — it is the kind of strain veteran growers and aficionados return to for its hashy, incense-like aroma and clean, glass-clear cerebral high. The "x hempstar" search query alone draws 2,500+ Bing impressions per month, signaling a passionate ongoing community. Royal King Seeds offers feminized Hempstar genetics in our regional shops with full germination guarantee.
Effects & Medical Use
Hempstar starts with a fast, energetic head rush that morphs into a sustained creative buzz lasting 2-3 hours. Users report sharp focus, music appreciation, and elevated conversation — making this a hallmark "wake-and-bake" or social Sativa. The relatively moderate 14-18% THC ceiling makes it more forgiving than modern 28% chemovars, suiting both occasional and regular consumers. Medical reports include relief from depressive mood, ADHD-style focus issues, and chronic fatigue. The terpinolene-and-pinene-leaning profile may also support mental clarity and respiratory comfort.
Growing Hempstar
Hempstar is for growers willing to wait. The 10-11 week flowering stretch is long, but vigorous growth and Sativa stretch (1.8-2.2x) reward SCROG, SOG, or topping training. Indoor: keep canopies open, run 18°C nights to maintain trichome integrity, EC 1.4-1.8. Outdoor: plant early in long-season Mediterranean climates; harvest mid-to-late October. The Sativa structure benefits from selective lower-third defoliation. Mold resistance is moderate-to-good. Expect 400-500 g/m² indoors and up to 700 g per plant outdoors when grown in living soil with proper amendments.
