The original breeder Sensi Seeds say it's a closely guarded secret, but the lineage known to the cannabis community is a 3 way cross combining a Haze X Northern Lights #5 X Shiva Skunk. The flavor from Jack is woodsy with hints of orange and lemon zest. The aroma is equally captivating, featuring a peppery, citrus scent that makes it hard to resist. This legendary strain has a dazzling double-edged potency and a stratospheric cerebral high that is underpinned by a breathtaking body buzz with seismic power. Smokers should be prepared to feel the earth shake beneath their feet, which can be a very pleasant feeling when your head is firmly in the clouds.
