depends how good you are your not gonna be raking in the doe with your first grow. if you do really good and you have great mother plants it won't be hard at all. but its gonna take a good amount of cash to start up and you won't make a dime for atleast three months so your gonna need to buy all the equipment, electricity, food, nutes everything you need to live and grow for the first 3-5 months before you make anything. but if you start out outdoors it won't cost you too much just seeds, some nutrients, soil, water and your good to go but the limits are gonna kill you. it would really be easier to start out illegally basically fuck the law aint no man gonna tell me how to live. lol
