PVC build. Stock tank Aquaponics
This aquaponics build shows building two aquaponics grow beds from concrete mixing trays. They can be picked up from home Depot.
I'm using 1" pvc bulkheads, simple process, use a 2 and 1/4" hole saw, drill the hole, clean up the burrs and insert the bulk head with some silicone.
You doing something similar to Jack Spirko did on his recent YouTube series?
That’s the first thing I thought too...
