From the lab panel — 17-23% THC, <1% CBD. From grower reports — 500-700g/m² yield, citrus/skunky dominant in cured flower. advanced grow.

Lineage: Gary Payton × Burmese Pie sits at the core of Slam Dank Feminized, and that parentage shows up in every grow cycle — tight internodal spacing, dense colas, and a citrus-forward nose with a skunky edge that creeps in during the final weeks of flower. THC tests routinely land in the 17–23% range, so this isn't a plant you harvest early and call done; those extra days in weeks 9–10 matter.

The challenge is real. Sensi Seeds rates this one advanced, and growers running it indoors will find the compact Christmas-tree structure rewards careful canopy management more than hands-off grows. Yields top out near 500–700g/m² under dialed conditions, but you have to earn that number — the plants are thick-growing and slow to respond to training adjustments. Works in both indoor and outdoor setups. Best suited to experienced growers who already have environmental control locked in and want a high-THC cultivar with a more complex terpene mix than the usual sweet-only options.

Growing Slam Dank

Slam Dank is rated as advanced difficulty, making it best suited for experienced cultivators who understand advanced techniques. This strain rewards meticulous attention to detail with exceptional results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 500-700g/m². Plants typically reach 100-180cm 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 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 the dense, heavy buds this strain produces.

Flavor, Aroma & Terpene Profile

Slam Dank features a citrus, skunky, sweet, earthy 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, Slam Dank 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.
