yeah dave has it rightyou need some soil, some ferts, some seeds, sunshine, water and this forum to help you aknowledge any problems that occure
once you get your hands on some seeds you need to decide how much effort you want to put in. you can simply mix some slow release ferts in the soil and hide your plants in a forest and return to harvest at the end of the year, but your bud wont be that quality. the more effort you put in the better the final product will be, especially when it comes to watering. you dont want to over water or under water, that is the most difficult thing you will encounter, is finding the right amount of water, its a common noob mistake to over and under water.
I grew for the first time last year and i can tell you its fairly easy with the help of rollitup, and i did it all organically watering every few days, while my friend just put his in a forest with slow release ferts and watered only a few times. my final product was better than his because i watered more and put more effort into my plants, but at the end of the season we both had bud. so the questions you have to ask yourself are: how much effort do i want to put into these plants, where am i gonna grow them (find a good spot and dont tell ANYONE), and wat do i want for ferts organic or chemical.
