Must Try For All Kush Lovers

If you are a fan of Kush genetics, K.O. Kush is a “must try.” This Indica-dominant (70%) hybrid is a three way cross between Afghani, Hash Plant and Northern Lights. Due to its heavy Afghani heritage and genetics, it can perform well in colder climates and harsher environments which may help exhibit blue or purple colors.

Resilient, Compact And Bushy

Growers can expect to harvest indoors in just 8 weeks of flowering and outdoor growers can expect to harvest by the end of September. Indoor yields go up to 500g/m2 and outdoors K.O. Kush can yield up to 650-800g/plant. Usually staying around 90-140cm indoors and at around 180-190cm outdoors, it is a compact and bushy plant with great resistance to pests and mold. Usually tests at 19% THC and 0.8% CBD.

  • Doesn’t require any special care or attention;
  • Has great resistance to pests and disease; and
  • May need support in final weeks of flowering.
