Hydroponic grow room set-up

A LLL...... you all know i've been trying to get a guerilla grow started....well, I've decided to put off growing until I live by myself (a wise choice in my view). I'm currently looking into various grow-boxes for hydroponic growing, and I've found some really cool ones. I'm thinking, a fully automated grow box? Does anyone else use this? The reason I'm looking into hydroponics is because I heard it's the method with the lowest chance of being found out (cause it's in your house!), but also because using soil might look a bit odd. Soooo....any thoughts on what type of grow box? I've been looking at the PC case stealth type but they look like the're too small to fit a good size plant.....

Is your number one goal stealth? Something simple are passive hydro setups, they dont have any moving parts. Check out the Hempy Bucket.
