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.

Step 1: Planning Your Build

Here are all of the measurements from my initial sketch/plan. 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.

Step 2: Base

Start with the 2x3 ft rectangle, framing the bottom

Step 3: Bracing

Add bottom(floor) braces & front, lowest shelf brace

Step 4: Bottom Shelf

Add front shelf legs & screw shelf pieces on to them.

Step 5: Middle Shelf

Add middle shelf legs & attach shelf pieces.

Step 6: Top Shelf

Add top shelf legs

Step 7: Top Shelf

Add top shelf pieces.

Step 8:

Add braces that attach the shelf legs of different shelves together for stability.

Add inner shelf braces & shelves.

Step 9: Make It Mobile

When completed to this point, you can (optional) add casters for easier movement(if needed).

(2"-3" rubber wheels work best)

Step 10: Grow Beds & 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. Uniseals work, as well.

Step 11: Add the Tanks/Aquariums & Pumps

Add 1-2 tanks/aquariums(5 &10 gal), 1-2 small pumps(lift

must be between 3 & 4 ft. for best results), aquarium gravel & any live aquatic plants.

Step 12: Choose Your Food

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).

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!
