You know.. cancer is a part of evolution as well? It's natural... but is it good?
If you believe you can live a life without antibiotics - be my guest. I used antibiotics last time about 11 years ago - and it was a misdiagnose i had mono... but still i know people that do them on a yearly base...
The bottom line is still, and everybody except you can see it (maybe you are high):
1) hydro has the potential to be better than "soil"
2) hydro is not so environmentally friendly as "soil"
3) hydro can (doesn't mean it will) yield more per m2
4) hydro can (doesn't mean it will) have superior quality
5) hydro is harder to implement correctly
x) /// i had to put this one /// hydro is used in SPACE on a SPACE SHIP/STATION
i rest my case
