I built my cabinet in an armoire, and after some tweaking, reliably pull 6 ozs of grass from it every 2 weeks or so.
I basically just built the whole system from mother to veg to flower SoG style using Al B Fucts guide, and its working great for me.
I got the armoire off craigslist for 50 bucks, and it sits in my office in front of a window, where it vents in and out thru the window for air and cooling.
You would never know in a million years that it was a grow cabinet.
Armoir are cool cause they look like they are supposed to be in your house, and they are very easy to make air/water/light
tight with a little aquarium silicon and some weather stripping.

Everyone makes the mistake of thinking BIGGER is better. WRONG! Smaller is better.
The tank has to be STURDY, and dark and not allow light in. I suggest a 8 gallon, with 6 gallons of water, or use 5 gallon buckets.
The ting about BUBBLEPONICS is the rapid growth that comes from having a feeder tube feeding the cube and root ball 24/7 when it is just a sprout and a small plant. You have to raise the lights an inch daily,everyday, to accomadate the rapid growth.
