well i can only guess that you are talking about it going on it's own in the wild.. so no it would'nt be hard for it to grow on it's own. but when it's hydro i would have to disagree on how it would be so easy as there would have to be some common sense and know how to let it grow the way it needs to.

and i even would have to disagree with u on the easy part altogether as when nature is growing, it does what it needs to. but when man is involved thats a whole nother story so one would have to have some knowledge and understanding of how it all works for it to work. cause if it was a (weed)as u say then u could just throw seeds in the wind and come back in 2 or 3 months to a finished product right...wrong.nature knows just what to do mad does not thats why u have to learn as much as u can b4 just going into it blind like most do thing aww it's just a weed i can just plant it and water it and it will grow most of the time it does not work as u should be able to tell on this site alone.
