Sweet setup on the lights could potentially grow a freaking lot...

I think generally speaking soil is slower and easier, and hydro/aero is faster and harder..

I think just about the fastest you could get to a healthy harvest would be aeroponics with 24hr veg and 12/12 hps flower some people do 13/11.. but It seems like no one knows if that's worth it for certain or not :P

one thing to consider is, It's alot easier to make a dirt garden bigger, just get bigger pots... aero is a little more difficult once the plants are established.

I'll be growing aero when I get a room up and running, I like the idea of being in absolute complete control of what's going into the plants.. and while soil is fine, It's harder to keep track of just what is going into your lungs
