Sandponics (iAVs)

iAVS systems are relatively simple to build and require only a few basic materials. However, careful consideration should be given to the design of the system to ensure optimal performance.

Here are some of the materials needed to build an iAVS system, along with design considerations and other important factors to keep in mind.

1. Sand Bed Material

The primary material needed for an iAVS system is a medium-coarse sand bed material. This sand should be free of contaminants and have a particle size between 0.5mm and 2mm. The sand bed should be at least 30cm deep, but can be deeper depending on the size of the system.

2. Water Source

An iAVS system requires a reliable source of water for irrigation and fish tank replenishment. This can be from a municipal water supply or from a well or other natural source.

3. Fish Tank

A fish tank is required for an iAVS system as it provides nutrients for plant growth through fish waste. The size of the fish tank will depend on the size of the system, but should be large enough to support a healthy population of fish.

4. Piping and Valves

Piping and valves are used to transfer water between the fish tank and sand bed, as well as for drainage purposes. These components should be made from durable materials such as PVC or ABS plastic.

Design Considerations:

- Site selection: Choose a site that has access to a reliable source of water, is level, has good drainage, receives adequate sunlight, and is protected from strong winds.

- System size: Determine how much space you have available for your iAVS system and choose an appropriate size based on your needs.

- Plant selection: Choose plants that are suitable for growing in sand beds such as leafy greens, herbs, tomatoes, and peppers.

- Fish selection: Choose fish that are suitable for aquaponics such as tilapia, catfish, or trout.

Other Important Factors:

- Maintenance:

Regular maintenance is required to keep the system running smoothly. This includes monitoring water quality, checking for clogs in the sand bed, and maintaining proper fish health.

- Cost: While iAVS systems are relatively inexpensive to build compared to other growing systems, there are still costs associated with materials and ongoing maintenance.

- Community: Joining an iAVS community can provide valuable support and advice from experienced growers.
