Quick read: 17-22% THC, 80-150 cm mature height, 8-10 weeks bloom. Genetics: G13 x Hash Plant Feminized (Seed Supreme genetics). Difficulty: moderate.

Lineage: G13 x Hash Plant — two strains with a reputation for heavy resin production and a grounding, earthy character that leans toward the classic indica side of things. The cross sits at 17–22% THC, which is a meaningful range: lower-end phenotypes are manageable for regular sessions, while upper-end cuts hit harder and are better suited to evenings. Expect a smell that opens with damp earth and closes with a faint sweetness — nothing sharp or citrusy, just clean and old-school. Indoors, growers are pulling 400–550 g/m² after an 8–10 week flower run, and the plant handles both indoor and outdoor setups without much complaint. Difficulty is moderate, meaning it rewards some experience but won't punish a grower who's done a run or two before.

Best suited to someone who wants a resin-forward strain with familiar flavors and doesn't need a lot of hand-holding from the genetics.

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 Seed Supreme, 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.

With THC levels reaching 22%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

G13 x Hash Plant delivers THC levels of 17-22%, 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 G13 x Hash Plant

G13 x Hash Plant 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 400-550 g/m². Plants typically reach 80-150 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

G13 x Hash Plant features a earthy, 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, G13 x Hash Plant 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.
