There is also a "ruderalis" or "auto-flowering" strains of cannabis. These strains are hybrids that have been bred to have an ability to start making buds automatically after a few weeks.

You can do it indoors, outdoors, or hydroponics style. It's all up to you.   Growing weed indoors has many advantages when compared to the risks associated with growing marijuana outdoors makes, what with threats from theft and possibly the law if it is illegal to grow where you live. By growing marijuana indoors you can control the ambient conditions just exactly as you want them and grow a nice healthy cannabis plant. Growing your plant in the wild allows you to avoid any nosy neighbors and avoid being caught red-handed, but it does force you to relinquish an element of control: You can't control the weather, disease, thieves, or how they grow. However, outside also eliminates the need for an indoor growing room, saving you loads of money initially. Hydroponics is the term for growing plants (any kind) without soil. Believe it or not, they don't actually need it. While soil is obviously a source for nutrients, they can be had in alternative ways.

Summary:
Know the law. Know the difference between the strains. Get your mitts on some seeds. Choose a spot and/or method.
