I guess, growing things is quite easy, just that there are more complicated methods which can produce better results, but not always. In reality, all that you need to grow anything is a pot, good soil, water, fertillizer and a light source. All of the hydroponics crap, grow lights, and whatnot are for those who wish to optimize and maximize the performance of their crops. With soil, its pretty hard to completely mess everything up, where with hydroponics, there is a greater chance for mistakes to be made.
To answer the question, you'll do fine with just nothing but the basics. There's a lot of growers out there who successfully grow their plants in a bucket by the windowsill!
