This indica dominant strain from Heavyweight Seeds is a seriously heavy hitter in all departments. Heavy yields and a heavy, heavy high, K.O. Kush is a must for lovers of all things Kush. A short, dense plant, it grows outwards and not upwards with an abundance of bud covered side branching. In fact, the bud to leaf ration is so good it makes KO Kush really easy to manicure. Good mould resistance also makes it a great choice for growers in cooler climates. With both sky high THC levels and big harvests, Heavyweight K.O. Kush is without doubt the main contender.
