Vertical tower system. Wonderful growth.
This system is running on 24 volts off 2 solar panels.
You will notice the pockets that are fixed to the 100mm (4") PVC pipe. We are trialling these pockets and have devised a water delivery system that deliveres water to the plants in the tower without the need to have some kind of media in the tower.
The water delivery system has been the hard part because fish water, even very well filtered fish water, has organic solids suspended in the water. Finding a system that will not block while delivering the very minimum of water has been the task.
