I completely have to agree with Stinky.....read up. After 3 or so failed attempts you should be following the directions to the letter. I can't speak for soil......although Stinky certainly can.....but I can tell you that if you do things EXACTLY as you are told in hydro you will get a good grow if you have viable seeds to begin with. Don't improvise or "get by with" Otherwise, stick to buying because it will save you heartbreak later.
