So what is auto-flowering? Auto-flowering characteristic grants a cannabis plant the ability to completely flower without the need for reduction of day-light hours; in turn, eliminating the need for a timer. It will grow consistently well and finish under 24 hours of light - from sprouting to harvest - in eight weeks, although you can achieve similar results with 18 hours of light per day; if you like to give your room time to cool down, for example. The point is, with Lowryder, there is no need for a change in the light period to induce flowering, nor is it necessary to have separate vegetative and flowering rooms!
