I'll try and get some pics. I'm using an indoor Apollo grow tent (4x2x5), which allows for two plants comfortably using my DWC setup.
I built a DWC system, by purchasing two 5 gallon buckets from Lowes. Drilled holes in each for the air line (I used a 4" air stone for each bucket). Bought an air pump from Amazon (the kind you use for fish tanks), along with the two net pots which fit on top of the buckets. I used Hydronton (clay pebbles) as the growing medium (opposed to soil, rockwool, etc). The DWC bucket system is about $25/ea to build. The tent was $120 I think. I went all out on the lighting, as I wanted the best I could find, yet remain energy efficient, so I went with Platinum LED. So far the setup does a great job. I started with soil in smart pots at first, however found myself dealing with a ton of gnatts (because of the soil). It's also messy. With the DWC setup, I don't need to be concerned about checking it every day to ensure the plants are getting water. Also, nutrients are now really easy to manage. About once a week, I have to change the water in the buckets (which is really easy). Other than that maintenance is really simple.
It doesn't take up much space. The footprint is 2x4 feet x 5 feet tall. The larger the tent, the more lighting you need. This equates to more money.
My next grow is going to be peppers, actually habaneros. For some reason, my habaneros will not grow outside. Looking forward to seeing some serious progress indoors. Contest anyone?

It's also great for starting plants. I'm thinking about starting tobacco in the tent, and then transitioning to soil outside.
I spent days researching how to setup an effective system. For some reason, no one really clearly shows how to setup hydro the right way. If anyone is interested, I would be happy to create/post plans w/ pictures.
