i always point people in the direction of home made dwc systems,easy to use and maintaine cost about $25 and has never ending option to what you can come up with.you could use your same tub for dwc then later on down the way turn it into an aeroponics sytem if you like or a recirculating drip.you dont really want to go out and dump $700-800 on something u might not like down the road or something that always has some problem like bigger aeroponic systems that you need to trouble shoot whal your plants are dying verry quickly.just a piece of my mind
