The shortest version: Willits Family Farm's take on indica genetics, 20% THC, 8-9 weeks flowering, moderate grow.

Lineage: Skywalker OG × Sour Diesel × Northern Lights, bred by Willits Family Farm into an 80/20 indica-dominant feminized strain that leans hard into the OG side of its family tree. At 20% THC and an 8–9 week flower cycle, it's not the fastest run on the calendar, but the payoff is a pine-forward smoke with a clean sweet finish and harvests that consistently land around 450g/m² when plants get dialed-in light and steady feeding.

Difficulty sits at moderate — this one responds well to topping and benefits from a structured canopy, so growers who've managed a few photoperiod runs won't find much to trip them up. It performs indoors and out, though indoor environments give you the most control over the density and resin development these genetics are capable of. Best suited for growers who want a nighttime-leaning indica with recognizable OG character and don't mind putting in the canopy work to earn it.

Genetics & Lineage

Mars OG traces its genetics to 80% Indica/20% Sativa (Willits Family Farm). 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 Willits Family Farm, 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 20%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Mars OG delivers THC levels of 20%, 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 Mars OG

Mars 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 8-9 weeks with yields of 450g/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 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

Mars OG features a pine, sweet terpene profile that develops complexity throughout the flowering cycle. A smooth, candy-like sweetness defines the flavor, with subtle complexity on the exhale. 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, Mars 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.

Who Should Grow Mars OG?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
