Ultra White Amnesia: A Sativa-Forward Powerhouse

Ultra White Amnesia marries two cannabis classics into one vigorous hybrid. Drawing 75% sativa influence, this Ministry of Cannabis creation channels the euphoric, cerebral rush Amnesia is known for, while incorporating White Widow's balanced foundation. At 22% THC, it's a strain built for growers who appreciate both yield potential and potency. The result is a plant that drinks deeply during growth, rewards consistent feeding, and delivers dense, resin-coated flowers by week nine or ten. Whether you're in a Maritime greenhouse or an Ontario basement, this cultivar thrives under attentive hands.

Cultivation Notes for Canadian Growers

Ultra White Amnesia flourishes indoors under controlled light cycles and reaches medium height, making it manageable in standard grow tents across the country. This strain is a hungry feeder—bump nitrogen through vegetative growth, then transition to phosphorus and potassium during flowering without holding back. Monitor EC levels closely to avoid nutrient burn, particularly if you're working with hard water common in Prairie regions or coastal BC. The final two weeks are crucial: cease feeding and run clean water only, flushing chlorophyll and residual salts from the substrate. This step amplifies the complex flavour profile and ensures a smoother smoke. Expect typical flowering around nine to ten weeks; patience here pays dividends.

Effects, Flavour & Best Moments

Ultra White Amnesia leans sativa, triggering bright, conversational effects and mental clarity that suit daytime or social use. The White Widow parentage adds gentle body relief without sedation, creating a balanced experience. On the palate, expect earthy undertones with hints of citrus and subtle floral notes—complex enough to linger after the initial smoke. The aroma intensifies in the final weeks of bloom, filling a grow space with peppery, piney character. This is the strain for evening gatherings or creative work, where your mind needs freedom but your body appreciates a soft cushion.
