The most important thing is how you grow not what you grow in. I have grown both and hydro is quicker and if done right will reach it's highest potential. That is the same true for soil. It took me several batches of hydro growing to get it right, I prefer it because it is quicker, but I will admit I think the taste may be a little better in soil. Hydro is much less forgiving then soil, so expect to grow a few batches before you get it right.
