Aquaponic Cart System
This gravity-driven, indoor aquaponic system can be built in an hour. It uses the Nitrogen Cycle to aid in maximum plant growth. This is a symbiotic relationship that benefits you in two ways-You grow edible plants & you can use edible fish, as well. Beneficial bacteria break down the ammonia & fish effluent, converting it to nitrites & nitrates that can be absorbed by the plant roots.
Plan With Measurements
This is the initial plan, but can be adjusted to specific measurements needed. With these measurements, total cost of system is around $200-$250, using all new materials.
Framing
Start with the 2x3 ft rectangle, framing the bottom.
Bracing
Add bottom(floor) braces & front, lowest shelf brace.
Bottom Shelf
Add front shelf legs & screw shelf pieces on to them.
Middle Shelf
Add middle shelf legs & attach shelf pieces.
Top Shelf
Add top shelf legs.
Top Shelf
Add top shelf pieces.
Inner Braces
Add braces that attach the shelf legs of different shelves together for stability.
Inner Shelf Braces
Add shelf/tank braces.
Inner Shelf
Add back shelf for optional 2nd tank(bottom tank collects sludge, top tank has the fish).
Make It Mobile
This completes the shelf construction. Add 4- castors, and wheels(2"-3" rubber wheels work best).
Grow Beds With Plumbing
Add totes with holes cut(for plumbing) in the totes & cut lids for plant baskets & PVC pipes. Aquarium caulk is used around plumbing, to seal it from leaking.
Adding the Tanks
Add 1-2 tanks/aquariums(5 &10 gal), small pumps(lift must be between 3 & 4 ft. for best results), aquarium gravel & any live aquatic plants.
Choose Your Greens
Add seeds or seedlings(leafy greens work great)& fish(FYI-Japanese shubunkins are very hard to kill and produce the needed ammonia to kick of the nitrogen cycle).
Light It Up
Add/attach plant lights/bulbs for maximum indoor growth. Within 4-6 weeks you can be producing enough salad items to feed a family of 4. Enjoy!
