There is organic hydro. If you think that there is no chemicals in soil think again. People gettig sick on hydro is because of crappy handling or shit added to make you think it's hydro. If you didn't see it grow , how do you know ? Hydro rocks ass. Total control is the only way. Other wise you are at the mersy of mother nature. Sometimes good ,sometimes bad. Hydro is rock solid once the person growing gets it down.
