There is a method called "Fertigation" the article wrote by Ed Rosenthal in Heads Magazine. That would be the best way for you to start out in hydro. Start your seeds in 2" rockwool cubes. Mix a balanced solution (mild) with a stable ph of about 5.8. when the roots start to pop out the bottom move the cube into a Large rockwool cube. From there take the large cube and place it in a pot of soil. Water the soil with regular clean water. water the cube once or twice a day (when ever it's looking dry) with your hydroponic solution. make it stronger according to the chart your nutes suggest per week. I had great results doing so. The dirt provides a stable medium for your plant wich will help in case of errors.
