I am using hydro. Some may not like the next thing i say but this time around i am not going to use nutrients. We have taken a $700 pay cut a month so we really cant even afford to think about buying anything. It sucks and thats life. This was my first grow so i really just wanted to see how the plant grew and acted before i start nutrients. I am doing the same with my veggie garden. I have never grown anything before so this is my way of teaching myself. Come sept. i will be getting all the nutrients that i will need and an additional light.
