Look.It's simple, if you want to go hydro it's a bit more detail oriented that growing in soil.Unless you believe and trust in blind luck, then if you have decided that DWC is the way you're going ,then be prepared to shell out a couple hundred for meters and nutes,and ph up and down,it's that simple.Hydro may be the best way to go , but you can't prove it by me.I'm working with a couple different hydro systems ,but until I see results for myself, then I consider all that I've heard and compare it to my results and either decide to try and adjust from there ,or go back to what I know works.Time will tell.
