GG+4 Gorilla Glue Grow Update!, say that 10 times fast after a few hits! Anyway I filled the reservoir with a light sanitizing solution and ran the system, without nozzles to flush more volume through everything. I maintain 100 psi in the system and  80 psi at the nozzle side, when the nozzles are installed. With the 1/4″ nozzle supply lines open with no nozzles allowing lots of volume to pass. You can see the nozzle side gauge down to 40 psi during the cycle.

In the picture above you can see the cycle timer to the left of the gauges and above the blue ball valve. The indicator LED’s are both energized, the top one indicates the 12 volt power is on,  the bottom indicates a cycle in progress.

This pressure run tests the supply pump and components along with the reservoir return pump. I will start the seeds tomorrow. It was -2 degrees night before last and the domestic water system in my living space doesn’t run so well below 20 degrees so……..I’ve been busy with that but outside temperatures are up and things are running. While the Aeroponic System is not affected.
