Green-O-Matic is an autoflowering strain with a short flowering time and high yields. If you are not blessed with the virtue of patience and out for a heavy harvest, you should give Green-O-Matic a try. After only 6 weeks of flowering in a SOG setup you can expect a yield of up to 700g/m². And the THC level of 15% is not to be despised. Fast-hitting and long-lasting effect.
