I read a recent article in The Age (Australia) about the difference between natural grow and hydro. Because of the increased number of crops and being able to hide it indoors, hydro is obviously taking over. The problem is that many growers are adding loads of chemicals to the brew and the results are starting to show. There have been several recent cases in Australia of people going into deep depression/suicide, mental instability, inability to sleep, etc. One long time weed smoker told the story of how going to hydro nearly cost him his life. He went clean for 4 months then back on to natural and he's A-okay now. With the world starting to recognize the marijuana shouldn't be the focus of law enforcement funds/activities, I hope the hydro problem doesn't cause the legalization effort a major setback.

Personally, I prefer natural. Back in my days of using a bit of E, you never knew what you were gonna get and hydro from an unknown source is a bit that way. I guess its time to get off my ass and start growing my own!
