DIY Ghetto HP Aeroponics build 100psi. This is the absolute first picture when the console was installed:
Everything wired and added some armaflex for sound insulation. Manual switches for "bleeding out" the system by opening the solenoid valves manually at res change. I can also manually run the return pump while cleaning the system at harvest.
Here's the bucket design. Two 8 gallon bucket sits on top of each other. The upper bucket has a bunch of holes in it. It also has a paint filter bag that fits perfectly in the first bucket. The netting gets bigger and bigger when it's being filled by roots.
Thought process is roots can get fine nutrient spray mist and also passively uptake nutrients from the droplets stuck in the netting.
Last picture is to show the buckets installed and some root pictures. Your able to see the filter bag also.
