Start with a tent(i’d get a 4x4x 6+ ft), air movement fans, exhaust fan, odor filter and most importantly, a light. I have cheapo ‘blurple’ LEDs but if you have a good budget, buy something of better quality. You need to decide on soil or hydro, organic or chemical fertilizers too. I do organic soil. Seems easier to me. I have junky lights in a 3x3 tent and I get over a pound a year. Really good hobby. Do some reading on this site and others and model your grow after some that look like you could do easily then you will figure out better and better ways to make a grow work for you. Good luck.
