Barney's Farm runs this as a indica feminized line — 24-28% THC lab range, fruity/sweet-dominant terps, 8-10 weeks from flip.

Lineage: Runtz × Layer Cake, both Barney's Farm cuts, stacked here into a feminized indica that flowers out in 8–10 weeks and can push 500–650 g/m² under decent light. That yield range is realistic for moderate-skill growers running either indoor setups or a sheltered outdoor season — the kind of Canadian summer you'd get in southern Ontario or coastal BC works fine, provided you're watching for late moisture. THC sits in the 24–28% band, so this isn't a casual daytime smoke; expect a body-heavy come-down with a noticeable mood lift before it settles.

The terpene side leans fruity and sweet with a grounding earthy base — think baked goods cooling on a counter rather than anything sharp or chemical. Plants stay manageable in height indoors, and the moderate difficulty rating means you'll want some runs under your belt before attempting this one, but it's not a specialist project. Best suited to home growers chasing a high-yielding, high-potency indica without needing to babysit it constantly.

Genetics & Lineage

Runtz x Layer Cake traces its genetics to Runtz x Layer Cake (Barney's Farm genetics). 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 Barney's Farm, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and sleepy 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 28%, this is a potent strain recommended for experienced users — newcomers should start low and go slow.

THC Level & Potency

Runtz x Layer Cake delivers THC levels of 24-28%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Runtz x Layer Cake

Runtz x Layer Cake 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 500-650g/m2. Plants typically reach 90-160cm indoors. This strain responds exceptionally well to SCROG (Screen of Green) and LST (Low Stress Training), which can boost yields significantly. 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Runtz x Layer Cake features a fruity, sweet, earthy terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. 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, Runtz x Layer Cake 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.
