Hydro grown cannabis and soil grown are no different from each other. The only thing that makes "dro" better, is the short time period it takes to grow. It doesn't take near as long as soil, and doesn't require as much care. Hydro is often grown using chemicals, and there I'll take an organic grown bud over hydro anyday.

People like to use the word hydro, because it sounds "cool." Kids have been using that word since my day with the shittiest weed possible.
