tiny and Ganja make several great points. I'm new to this hydro,too. That being said.. I started small. Small turns into big. Hydro grows way larger plants than small soil containers. You never have to worry about them getting rootbound as you do in soil. But you can screw things up in a second! Then you work weeks to correct it.

Starting with a res that large and never doing it before,is gonna be disasterous.. Start on a smaller scale,as opposed to going big from the start.Just some input.. I hope it helped. There are alot of hydro guys and girls here.. They sure know more about it than I do! But,I did say,I'm learnin'!Slow and small!
