Few strains carry as much history as Amnesia Haze. After she appeared in the 1990s, her soaring high and fresh haze aroma made her a fixture on cannabis menus, and growers around the world have chased her ever since. Royal Queen Seeds keeps this classic alive as feminized seeds, so you can grow her at home year after year.
Her reputation isn’t just nostalgia. Royal Queen Seeds’ Amnesia Haze earned 2nd place in the Bio Haze category at the Highlife Cup, proof that the original formula still competes. Built from the original Amnesia Haze line, she is 70% sativa and 30% indica, with THC levels of up to 22% and a medium CBD level.
Indoors she reaches 3 to 5 feet (90–150 cm) and finishes in 65–70 days (about 9 to 10 weeks), producing 21 to 23 oz/m² (595–650 g/m²), making her one of the most productive strains in the RQS catalog. Outdoors, in full sun and a warm climate, she climbs to 6 to 7 feet (185–215 cm) and can deliver 23 to 25 oz/plant (650–710 g/plant) by late October.
Flavor and Effects: The Haze That Started It All
Amnesia Haze greets you with zesty citrus and fresh herbs, followed by cracked pepper and a dry, earthy base. The smoke is light and fruity on the inhale, with that unmistakable spicy haze finish on the exhale.
The high lives up to the name. It launches the mind skyward with an almost psychedelic, expansive rush that can make time feel elastic and thoughts drift in unexpected directions. Royal Queen Seeds describes it as powerful and long-lasting, with a physically relaxing undertone that keeps the body comfortable during the ride.
It feels like floating above a canal on a warm evening, watching city lights blur together. She is a strong smoke, so experienced consumers will appreciate her most, and newcomers should start small.
Growing Amnesia Haze: Patience Pays Off
Indoors, Amnesia Haze stays surprisingly manageable for a sativa. Topping and a SCROG screen keep her height in check and let her long colas fill out evenly. With strong lighting and steady feeding, she rewards growers with heavy, resinous harvests.
Outdoors she needs a hot climate and a long season to finish well, so growers in cooler states should consider a greenhouse. She can be sensitive to weather swings, pests, and irregular watering, so careful attention through late bloom protects the final harvest. Allow about two weeks for drying and curing to bring out her full haze bouquet.
