To get a taste of hydro growing could I. Use a fish tank with proper lighting and pumps to get started. I just want to try a grow to get my feet wet and see if I gain interest before expending and real $. I understand generally thing grow a bit quicker...about 20% faster and the taste and general quality is betetr then soil grows. Is it something I should hold off till my soil grows produce or is it worthwhile to play with?
