Playin is exactly that when you start out with DWC. I'm thinkin I'm going to stick with compost or soilless mix as I seem to get better results, at least better yields. DWC is pretty labor intensive, especially if your nutes aren't balanced or you aren't using RO water. Keeping the pH just right can drive you nuts. Though I must admit I did learn alot about growin doing DWC and compost together.
