Does anyone have a hydro how-to guide?

Hey every one just wondering anyone out there has a guide on building a hydroponic system...I've searched on youtube but couldnt find anything.
i cant help but noticed all of these other systems charging hundreds when you can build it yourself for half the price at home depot. Anyways just wondering if someone out there can help me out

Thanks in advance

Just search the hydro forums. Tons of ways to do it. Most of them on the cheap. Lots of info here. Happy hunting.
