Welcome to MP. It is indeed enjoyable to grow your own and you will save money. A lot of new growers go into this thinking it is going to be far easier than it is. It is not like raising a vegetable garden, especially if you are growing indoors. I recommend that as a first step you start doing some reading to understand what it is going to take to get this plant to harvest. There is a lot of misinformation out there (especially YouTube), so beware. If it sounds too good to be true, it is. For instances, you are not going to be able to grow a pound of bud with a few CFL lights. This does take a certain investment of money to set up initially. So, I would encourage you to become familiar with the biology of the plant and the requirements to get it to harvest. Your budget for this project and the space you have available to grow in will determine a lot. We can help you set up a room, but will need to know what kind of budget you are working with. The actual growing though is going to be up to you. Things that are really important: nutrients requirements during the different phases of growth, good soil mixtures, room environment--temps, RH, etc, how pH affects plant growth, diseases and pests that strike cannabis.
It is a great hobby, but does take, time, love, knowledge, energy, and money.
