Ok, here's another system I've been helping/working on with a fellow named Robert. He just finished up at UCF. This build is near there.

The system will have 2 'river beds' and 2 raft beds.
The river beds, simply have media in them that the water constantly flows through. The pots/grow bags will be set to where the bottom of the vessel is in contact with the water. The water then wicks up into the soil mix.

In the fore ground right...is the plastic pallet that the IBC will sit on.
In the mid, is the 2 river beds...
In the background, is the 2 raft beds.
NOTE: the 2 river beds are elevated slightly. As we dig out the raft bed area, we will bring up the dirt level in the river beds.



The (clean) sump will be installed past the beds.
