I started out in soil and after growing 6 plants to harvest I decided I wanted to try hydro. I went with 5 gallon buckets for DWC setups. I started with a kit from amazon actually, that came with everything you needed.
My plants in hydro have been much healthier, and way bigger than when I was growing in soil. I was a newbie when in soil though, so things could be different now. I will always grow hydroponically though, because I fell in love with the results and ease of growing.
