This is an experiment in combining aquaponics with vermiponics.
The new outdoor garden will have for the AP portion (three) 4'x4'x1' 100 gal grow beds, (two) 2'x8'x1' 120 gal grow beds. The in-ground vat measures 2' Wide x 16' Long x 2-1/2' deep, about 600 gals. The bio-filter is made up of a 2"PVC loop with holes along it entire length, the pipe is burried in 8" of red lava. the water from the vat is pumped by a non submersiable pump of about 3000gph it circulates and supplies the GBs. the vat contains 150-2" goldfish.
(29) 5-gal buckets containing red wrigglers, castings, and feed for the worms makes up the vermiponics portion of the system. Each bucket is watered every morning, the excess runs off back into the vat to be pumped to the grow beds. Eventually this will be regulated by a controller.
