Fast Finishing Indica With A Kick

Green Ninja is an Indica-dominant (70%) cannabis strain, a cross of two legendary strains - Northern Lights and Afghani. Due to its Northern Lights heritage, smells and aromas will not be as pungent or strong - which, with relatively short size and stature, give the Ninja its powers. Despite its short flowering time of just 60 days and small size, it will still produce high quality harvests, usually testing at 22% THC and 1% CBD, with yields going up to 500-500g/m2 or 800g/plant outdoors, where growers can expect to harvest in late September.

Green Ninja grows bushy and has great branching, making for many collateral, strong and sturdy branches that get filled with dense and hard, trichome covered buds. Indoors it will usually stay around 90-150cm, but if given enough root space and vegetation time it can grow up 170-210cm outdoors.

  • Light to moderate defoliation will help to expose numerous buds to more direct light;
  • Doesn’t need much nutrients, usually staying under 1.5 EC; and
  • Great bud to leaf ratio and internodal spacing make for easy trim.
