Jack HererKarel's Haze
Intensely-flavoured, sativa-dominant hybrid that is highly potent.
Karel's Herer Haze combines two exceptional cannabis strains, namely Jack Herer and SSSC's own Karel's Haze. The resulting strain is a strong and potent sativa-dominant hybrid with a longer than average flowering time but whose qualities more than justify the extra wait.
The classic Jack Herer sativa mother has a most intense citrus sativa terpene profile alongside an open sativa bud structure and a sativa growth pattern with a thick coating of trichomes. Unfortunately it also has a 13-14 week flowering time which we needed to reduce in the subsequent hybridisation. Crossed with our best-selling Karel's Haze reduces the flowering time to 10-11 weeks. Much more realistic for the home grower!
Plants have a 75% sativa content producing an active, creative high. Karel's Herer Haze plants are medium/tall in height, with large buds. The terpene profile can be intensely citrus, with fuel notes. It's a very aromatic blend of gassy and Haze-y citrus fruitiness which produces a smooth vape/smoke with several delicious layers of flavour. With a powerful psychoactive effect you feel instantly relaxed. The Haze influence enhances creativity, with a long lasting and unusually powerful high.
Expect high yields of very high-THC weed.
