Spec sheet first — strain: indica, seed type: feminized, THC: 20-25%, yield band: medium, environment: indoor or outdoor.

Smell-first: crack a jar of cured Ultra Violet OG and the room fills with cold pine resin and a sharp citrus edge, earthy undertones coming in behind like wet forest floor. That nose tracks cleanly into the smoke. This is a Blimburn feminized indica pulling 20–25% THC, so effects lean heavy and physical — good for unwinding after work, less ideal if you need to stay sharp. Indoors, expect harvest in 8–10 weeks with 400–500g/m² under a dialed setup; it handles both indoor and outdoor environments without much fuss, though growers with at least one or two runs under their belt will get more out of it. Plant structure stays manageable, and the resin production is obvious by week six. CBD stays below 1%, so this isn't a therapeutic-ratio strain.

Best suited for intermediate growers who want a reliable OG-lineage indica without chasing something finicky.

Genetics & Lineage

Ultra Violet OG traces its genetics to Ultra Violet OG (Blimburn Seeds). This indica-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Blimburn 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Ultra Violet OG delivers THC levels of 20-25%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Ultra Violet OG

Ultra Violet OG is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm 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 40-50% 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

Ultra Violet OG features a citrus, earthy, pine, floral terpene profile that develops complexity throughout the flowering cycle. Bright lemon and orange zest punch through on the inhale, with a tangy, refreshing finish. 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, Ultra Violet OG 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.
