Lineage: OG Kush crossed with an undisclosed OG parent, Neptune OG sits squarely in familiar West Coast territory while still managing to feel like its own thing. At 23% THC, the effects lean toward the heavy end—this isn't a social-hour smoke, it's an unwind-after-work strain with a slow, body-forward onset. Yields run 450–550 g/m² under good light, and the 9–10 week flower window is honest—don't rush the flush if you want the earthy, dank nose to fully develop. The canopy stays manageable in both indoor and outdoor setups, though moderate grower experience helps when dialing in the feeding schedule; OG-dominant plants can be particular about nitrogen during stretch.

Best suited for growers who already have a run or two behind them and want a reliable high-THC OG-type without chasing something exotic.

Genetics & Lineage

Neptune OG traces its genetics to OG Kush x unknown OG lineage (Growers Lab Seeds). This hybrid-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 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 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Neptune OG delivers THC levels of 23%, 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 with a balanced head-and-body experience that evolves over time.

Growing Neptune OG

Neptune 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 9-10 weeks with yields of 450–550 g/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

Neptune OG features a earthy 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, Neptune 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.
