The specs in one line: 22-26% THC, <1% CBD, 8-10 weeks flowering, 400-550g/m2 reported. Best indoor or outdoor. moderate grow.

Lineage: Caramel Apple Gelato × King's Tart, both selected by Green House Seeds for resin density and structure rather than novelty. The result is a 65% indica-leaning feminized strain that tests between 22–26% THC and finishes in 8–10 weeks of flower — a window that suits both controlled indoor grows and outdoor plots in southern BC or Ontario where the season closes before mid-October.

Indoors, growers are pulling 400–550 g/m² under decent light without heroic effort, though moderate difficulty means she'll punish neglect during the stretch. The terpene profile runs earthy and sweet — think baked fruit rather than candy — which tends to hold well through a slow dry. CBD sits below 1%, so this is a THC-forward cultivar with sedating weight to the high. Best suited to growers who have a few successful photoperiod runs behind them and want a yielding indica that doesn't require boutique-level dialling to perform.

Effects & Experience

THC Level & Potency

Tarte Tatin delivers THC levels of 22-26%, 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 5-10 minutes, settling into the body as a warm, heavy relaxation.

Growing Tarte Tatin

Tarte Tatin 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 400-550g/m2. Plants typically reach 90-160cm 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

Tarte Tatin 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, Tarte Tatin 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.
