there are two kinds of HID lights: metal halide and high pressure sodium. I prefer to use only HPS as it works very well for both stages of growth

HID lights come in several different sizes. the most common are 400w, 600w, 1000w.

Be sure that you choose a light (or lights) that provides at least 25w of light per square foot for your growing space.

avoid using any kind of florescent lighting in flowering as the plants will produce a lot of leaves and small loose buds low in THC.
Not true my friend, i know plenty of growers using florescent lighting including CFL's, ya just gotta know what your doing.

Here is a link to a random goggle i thought i would back up my point. Im not saying hps for flower and Mh to veg isn't better, but also depends on the room a grower has, not to mention dropping 300 buck on a light set up as a newbie. Maybe after one grow they dont want to grow, waste of cash. I have LED's, but to much these days, anyway here is a link you could use to get cheaper set up.

Only an example as there are a lotta ways to use different lighting, but it is true hps will flower faster then these types of lighting, but i had rock hard buds under CFL's so look to see what fits your pocket and or space, growing methods. I hope this helps bro,

BTW, man there is a lighting thread that will tell you what different lights can do so i suggest that you get in and do some reading as it will help you with these sorta question and many more you will need to know before your done or even grown a plant. This my friend is easy to do,
