Initiating the flower cycle:
As you are most likely aware, cannabis is a photoperiod-sensitive plant which needs 12 hours of uninterrupted and complete darkness to bloom. You will need a space that has no light leaks, yet can still be ventilated, to flower properly. Anything from a converted armoire or closet, to one of the purpose-built grow tents on the market, can achieve this.
When you have decided that your plants are ready to flower, basically, that they are about half the size at which you can finish them, stop feeding your Grow fertilizer. You need to reduce the amount of Nitrogen in each feeding by half or more. Put your lights on a timer set to 12 on, 12 off. For efficient use of electricity, most people run their lights at night to take advantage of the cool night air and reduced kwH rates from the utilities company. It is very important that the dark period not be interrupted during the flower cycle, as it can lead to reduced yield, revegetating, and the Dreaded Hermaphrodite. If you absolutely must check the plants at 'night', use a GREEN light, as it is far less usable to plants.
