Soil less mix, like Promix or Sunshine #4, etc. It's a sterile media so you don't have to be an organic wizard to feed the plant. With real soil you can easily over feed because of nutes already in the soil. Don't reuse the media till you get a few crops done and have learned a bit. It's prone to serious Ph swings after a few uses due to the lime being washed out. Once you learn a bit you'll figure out how much lime and perlite to add and you can reuse it almost indefinitely.
Feed with Gen Hydro 3part at about 70% of recommended dose. Give them plain water every third watering to stop toxic salts from building up. Simple and cheap.
Start them in beer cups and transplant to 2 gallon bags after 3-4 weeks.Veg another 3 weeks or so and flip the lights to 12/12.
At first, you need to learn how to grow the plant and not worry about how to operate a system. Any problems that pop up can easily be solved with help from the people here at RIU.
Follow this simple plan and you'll be swimmin in buds in no time.
Good luck,
