About this Hybrid Strain

The breeders at Dinafem out of Spain set out on a mission to breed a strain that brought together the best genetics from Skunk #1, Northern Lights, and Haze into a killer hybrid. To do this, they chose to mate the legendary Jack Herer with the highly acclaimed Critical Plus. The result is a high-powered hybrid routinely testing at 20% THC and known for sparking the user with tremendous amounts of energy.

This strain brings a long-lasting energetic high that offers introspective insight. Users report enhanced ability to focus and improved mood making this an excellent choice for medical users with ADHD and anxiety disorders. Its high-powered psychedelic effects make it a great daytime strain to help tackle chores with confidence and increase productivity. Its pleasant flavors have been described as being similar to lemon-pine cleaner, with a bit of a spicy-tang on the exhale.

Critical Jack is a quick grow that can produce flowers in under 8 weeks. Perhaps its most beloved quality is its generosity, capable of yielding up to 2.5 lbs. of flower per plant. It’s a tall and resilient strain that is most often grown outdoors and can grow to over 3 meters in height.
