Double Black: G13 Labs' Indica Landmark

Double Black stands as G13 Labs' bold statement on pure indica breeding. By doubling down on Black Domina genetics—a strain that carved its legacy into 1990s cannabis culture—the lab created a strain anchored in Afghan landrace heritage, drawing strength from Northern Lights, Hash Plant, and Ortega bloodlines. The result is a straightforward, no-nonsense cultivar that delivers robust resin production and a heavy, grounded body effect. Indoor Canadian growers will appreciate the predictable 8–9 week flowering window, while the strain's natural structure suits compact setups and tightly managed gardens.

Growing Double Black Indoors and in Canadian Climates

Double Black thrives under controlled indoor conditions, where its pure indica character translates into manageable canopy heights and lateral branching. The 8–9 week flowering period fits neatly into Canadian seasons, making it viable for late-spring outdoor planting in temperate zones like coastal BC or southern Ontario. Indoors, standard LED or HPS setups support steady growth. Watch for the strain's vigorous vegetative phase—maintain airflow to prevent humidity-related stress, especially critical in Maritime and Prairie climates prone to mould. Feed moderately during flowering; dense bud structure can trap moisture. Expect solid resin production across the plant. Outdoor success hinges on selecting frost-free microclimates and harvesting before autumn rains intensify.

Effects, Flavour, and Consumption Moments

Double Black delivers a grounding, full-bodied stone rooted in its pure indica makeup. The 18% THC ceiling keeps effects measured—ideal for evening relaxation or wind-down sessions without sedation overdose. Expect earthy, piney aromatics with subtle hashish undertones reflecting its Afghan ancestry. The flavour profile leans woody and herbal, with hints of dark spice lingering on the exhale. Best enjoyed after sunset or before a long, restful evening when you can sink into the couch without agenda.

GeneticsDouble Black brings the dank back. This organoleptic strain, developed by G13 Labs, derives from mixing the infamous Black Domina with another Black Domina, hence the name "Double Black". Black Domina was released in 1998, the time in history when this amazing strain spread its green wings across the cannabis culture. It's a 100% indica strain that derives from Afghani hybrids, such as Northern Lights, Ortega, Hash Plant, and Afghan SA.
