more can go wrong with hydro....dirt is easy....IMO Dirt can/does produce nice plants

Might I suggest Sunshine professional Organic growing Mix...I get mine from a Feedstore(horses livestock) $30 for a 3.8 cu ft. block

Sun Gro Horticulture | Products | | Sunshine® Natural & Organic Mix #4

The #4 mix has more perlite for better drainage... if you live in a dryer climate use the #2 mix...it has abit more peatmoss for better water retention
