Why this one matters: hybrid genetics with a 21-26% THC ceiling and diesel/earthy-led terps. 8-9 weeks flowering, indoor or outdoor.

Lineage: The Chem Sister × Chocolate Diesel × Sour Dubb cross that became GG#4 built its reputation on resin production, and the numbers back that up — lab panels routinely land between 21–26% THC with a terpene profile that skews hard toward diesel and damp earth. Yields run 450–600 g/m² under a 600W setup with an 8–9 week flower window, which is honest for a strain that spends most of its energy coating buds rather than stacking size. It handles both indoor and outdoor environments, though Canadian growers running it outside should target a mid-September finish to clear the flower window before temperatures drop below 10°C in most regions. Difficulty sits at moderate — she rewards training (HST or LST both work) but won't punish a grower for a missed feeding day the way some high-THC lines do.

Best suited to intermediate growers looking for a heavy resin yield without the temperamental feeding schedule some other diesel-forward strains require.

Genetics & Lineage

GG#4 traces its genetics to -title">. 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 Zamnesia Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily euphoric and relaxed 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 26%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

GG#4 delivers THC levels of 21-26%, placing it in the high-potency category alongside powerhouses like Gorilla Glue and Girl Scout Cookies. 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 GG#4

GG#4 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 450-600 g/m². Plants typically reach 150 cm 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

GG#4 features a diesel, earthy terpene profile that develops complexity throughout the flowering cycle. Pungent fuel and chemical notes hit first, followed by an earthy, musky undertone. 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, GG#4 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 GG#4?

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.
