High yielding, larger auto with sativa dominance.
Amnesia XXL Auto is a high-yielding cross of Original Amnesia and Haze Auto. This XXL version has been bred from plants selected for their height and increased production.
Indoors, Amnesia XXL Auto produces plants that grow to 80 - 100 cm. tall producing yields of 550 - 600 gr/m2 in a cycle between 70 - 80 days. Grown outdoors, plants will be taller at 110 - 170 cm.
The scent of this cannabis strain is intense and features notes of spices and lemon. Despite having a THC level of 'just' 14% the effect is both powerfully cerebral and long-lasting.
