Welcome!
First and foremost, there is no "best" method. Everyone has their preferences and you won't find yours until you experiment and learn. Some more specs would be helpful, particularly with what LED fixtures you are going to run. Do you already have good genetics or are you going to run off of bag seed?
Also, just a recommendation, if you can return those plastic pots and order yourself some
smart pots, they'll be much better for your rhizosphere (root zone). Plastic pots are bad for the roots and allow for plants to become root bound, thus limiting their nutrient uptake ability.
Smart pots do a process called air pruning to the roots which prevents them from becoming wrapped around the pot and adds loads of benefits plus the nice thing of being cheaper than plastic pots.
If this is absolutely your first grow, might look into some organic soil methods as I believe these are the easiest for a beginner to approach. Once you have a run or two under your belt, step up into coco then your options are endless if you want to maintain organics or move into salts or even venture into hydro, where the big technical boys play. Best of luck on your run and again welcome to the farm!
One Love,
