Did a project combining
- Hydroponic system;
- Aqua-Culture system;
- Air-Lift Technology;
- Recycle + Reuse + Reduce of waste (Soda Bottles) into useful Grow Beds,
- Vertical Farming arrangement that saving foot print in limited space while "catch" more sunlight;
- Being able to use/install in high-rise apartment;
- Reduction of solar heat gain into indoor;
- Decoration as indoor green wall/space/curtain;
- Low water usage relatively compare to soil gardening;
- Low energy usage relatively compare to using water pump;
- Two possible resulting crops (Fish & Vegetables); and
- Most importantly, it is a SUSTAINABLE System!
Below are the pictures of the DIY Aquaponic Vertical Farming System with Air-Lift Pump.
A video can be found in my recent Instructables Post.
Step 1: Materials Used
- Tools : Marker, Tweezer, Pen knife, Scissors, Plier & Wire cutter;
- Aluminum wire (dia 2mm, to secure the soda bottles);
- Chain (can be plastic or SS type, to hold grow beds);
- Cloth hanger (to hang the whole system);
- Fishes & fish tank (to provide water & fish poo for the plants);
- Aquarium air-pump (4W 2 air output, to provide air both for the fishes as well as the air-lift system);
- Rubber air hose/tubings (dia 4mm for transporting air to both the fishes & the air lift system);
- Air terminal connector T-Joint with adjustable lever (1 input with 3 outputs);
- Aquarium filter wool (for mechanical filtration of the fish poo water before cleaned water returning back to the tank);
- LECA Balls (as a plant growing media in the grow beds);
- Used/Recycled soda bottles (DIY as grow beds);
- Vegetable seeds (quality organic leafy edibles' seeds)
Step 2: Preparing the Grow Beds
- Using a sharp pen knife cut an opening for planting (50mm width along the bottle length) along the bottle length;
- Also slit few holes for water drainage (at the bottom part of the bed - along the bottle length), as well as 2 holes for aluminum wires to be used for hanging (top part of grow bed - near the base of bottle).
Step 3: Shield Roots From Light
Use any opaque tape to tape/cover the base of the grow beds for shielding off sunlight to the roots, hence reduce algae growth.
Step 4: Aluminum Wire Hook on Grow Beds
Use the aluminum wire to secure both the bottom & the neck of the bottle to be hung on the chain.
Step 5: DIY Air-Lift Pump System
The details of the air-lift pump system can be found in my YouTube video - DIY Air-Lift Pump (Version 2).
Step 6: Final Assembly for System Commissioning
Assemble all the prepared materials, fill up LECA Balls in the grow beds, hook-up the air-lift pump and plant some edible seeds to be ready for full commissioning.
Step 7: Enjoy Fruits of Labor
Once the system has set to run 24/7, you just need to add the following 2 things to the fish tank;
1) Fish food; and
Let the fish do the job of supplying nutrients to the edibles and in a month or 2, you may harvest your fruit of labor!
