Some strains win a trophy and fade from view. AMG, short for Amnesia Mac Ganja, kept winning. This sativa powerhouse from Royal Queen Seeds took home cup wins in 2014, 2015, 2016, and 2017, a streak that speaks to just how consistently she delivers on flavor and potency.
She was created by crossing Amnesia with Mexican Haze, two classic sativa lines known for heady, expansive effects. The result is an 80% sativa / 20% indica hybrid with THC levels of up to 22%, aimed squarely at the mind rather than the body.
Indoors, AMG grows to 3 to 4 feet (90–120 cm) and needs 65–70 days (about 9 to 10 weeks) of bloom to produce 16 to 19 oz/m² (455–540 g/m²). Outdoors she can climb to 5 to 7 feet (150–215 cm) and yield 19 to 21 oz/plant (540–595 g/plant), ready in October.
Flavor and Effects: A Cosmic, Mind-First Journey
AMG greets the senses with spicy, earthy aromas and bright citrus, finishing with a subtle herbal note reminiscent of brewed tea. Long-time cannabis fans often find the profile nostalgic, a reminder of old-school haze that never needed candy flavors to impress.
The effect is where she earns her reputation. Euphoric waves start with the first toke and keep rolling. The mind feels light, free, and fast, like cruising down a cosmic highway at full speed, while the body receives only a mild, comfortable relaxation. Royal Queen Seeds describes the overall experience as balanced, clear, and stoned at the same time.
That intensity can overwhelm newcomers, and AMG isn’t really a before-work strain. She shines after a long day, when there’s time to put on music, sink into a good conversation, and let her take the lead.
Growing AMG: Simple Care, Rewarding Results
Despite her sativa dominance, AMG is far from fussy. She tolerates small mistakes in the grow room and doesn’t demand a complicated environment. Indoors, topping and a SCROG net help manage her upward stretch and create an even canopy of long, frosty colas.
Her bloom phase runs a bit longer than many indica-leaning hybrids, and outdoors she prefers long, warm summers that carry her comfortably into October. Growers who give her that extra time are rewarded with sticky, potent haze buds that more than justify the wait.
