I need advice for my grow room please!

I have some space in my room that i have measured down to about 12ft by 7ft by 8ft/8.67ft cause the roof declines. I was curious to know what kind of setup could fit it there. Its in a pretty big room i would just enclose it with canvas. Im more interested in a simple grow nothing too fancy so more then likely just do soil. Just need some information as far as lighting/cooling and anything else i may need. Also how many would be sufficient in there i can grow 12... Im open to any ideas tho that are within reason on price but help me keep it simple im by no means professional. If there are simpler ways for hyrdo im open once again but its hard my family will be assisting me with the finances for it. I really appreciate anyone who helps me out with this matter.​
