growing is as easy or as complicated as you want...
it can be as easy as throwing a seed in some soil under some light, watering when needed, and feeding it very basic nutes..
or it can be a 10000 dollar setup where everything is digitally controlled and feeding schedules are precise 3 part systems with additives and theres co2 tanks and water chillers and... well you get the picture...
the idea is to find your comfort zone.. keep your goals realistic... find out the basics and go from there.. it doesnt take a lot to grow weed.. and once you learn to grow, growing great amazing weed isnt difficult either.. its just like anything.. you gotta crawl before you walk...
