Aroma & Flavour
Super Silver Haze isn't just another sativa - it's the legendary strain that made other varieties step up their game. This high-energy hybrid has been turning heads since the late '90s with its cerebral lift, spicy-citrus hit, and electric jolt of creative energy.
Born from a three-way power cross of Northern Lights, Haze, and Skunk #1, this award-winning strain ruled the High Times Cannabis Cup three years in a row. Northern Lights adds structure and body, Haze brings soaring sativa energy, and Skunk #1 provides grower-friendly vigor and unforgettable aroma.
Effects are built for liftoff with sharp, energetic onset that boosts mood, dials in focus, and keeps the day rolling. Despite being 80% sativa, there's enough grounding to keep things balanced. Flavors are classic sativa with citrus peel meeting earth and haze, layered with subtle sweet and spicy notes.
For experienced growers, this rewarding challenge stretches like a true sativa but offers high fungal resistance. Indoor yields reach 1.6-2 oz per square foot, while outdoor plants deliver 21-25 oz per plant with proper care.
