not sure about hydro nutrients.
and you wont get a better yeild from hydro.
yeilds with soil growing and hydro growing all depend on everyones own personal growing conditions and skill and nobody will tell you any different.
i have never read about growing hydro or whats involved i only grow organic and its all i know.
it may grow faster i dont know?????.
but no one can say one or the other will give you bigger yeilds it depends on everyones own personal circumstances/growing tecniques and skills.
make some friends at your local grow store and im sure you will find someone that has some good strain clones and then start a mother plant way more time efficent
