Needs a bit more cleanup but you can see the plant structure and the RDWC setup.

Nice white roots doing laps in their own pool.
@Heisenbeans, I'd like to direct your attention to that 1/2" tee fitting and the water it's pushing out sideways in both directions. That sideways action is creating splash and churning the surface of the water in the tub. The splash is keeping the media inside the netpot moist and the churn is preventing any kind of skin from forming on the surface. In addition, these mix the water so nutrient solution is constantly flowing past the roots. Notice also that the constant impact of the water on the surface has created a hole where the roots aren't growing. No roots get hurt here; they just can't grow upstream. The net effect of all this is optimum oxygenation and mixing in the very place it's needed most.
The tee is important; just dropping the water straight down wasn't enough to consistently create all these benefits.
