Growing Aquaponics Basil Methods

By Using a Floating Raft

In this method, basil seeds are planted in grow sponge along with a net pot.

  • The net pot is then placed in the rafts where the roots will access the nutrient-rich oxygenated water, and due to this root system will grow quickly.
  • Nutrient-rich water will come from the fish tank after passing a physical filter to remove solid waste rather than a biological filter where nitrification will occur.
  • After germination, they are transferred into net cups and planted into the rafts to float over canals.
  • The water then recirculates after passing physical and biological filters to the fish tank.
  • After harvesting, the rafts are cleaned and dried to avoid killing the nitrifying bacteria present on the surface of the raft.
  • Advantage: It is best for commercial basil farming.
  • Disadvantage: Costly and challenging for beginners.

By Using Media Bed

This technique includes planting basil seedlings in a grow bed system. The plant roots in grow bed gets direct access to the nutrient water.

The roots themselves filter and clean the water before returning to the fish tank for the fish to live.

Media mainly used as growing beds are expanded clay pebbles, gravels, and lava rocks. Bell siphon and pump simultaneously while transporting water between the fish tank and grow bed.

  • Advantage: Easy for beginners to grow basil quickly.
  • Disadvantage: Its costs increase when large media bed setups are used.

By Using Nutrient Film Technique

In this technique, basil is cultivated in grow pipes in which holes are made according to the net cup size where seedlings are planted.

Grow media clay pebbles, tiny lava rocks, or gravel can be placed around the seedlings in net cups.

Water is pumped through the mechanical filter into the bio-filter and sump tank.

That water then divides half into the fish tank from the sump tank and half through the NFT channel or grow pipes where the plants are planted.

After exiting the grow pipes, the water is recycled to the filters and finally into the fish tank. This process repeats in the cycles.

  • Advantage: Basil roots are highly oxygenated in this method for rapid growth.
  • Disadvantage: In case of pump failure, the basil yield will begin wilting.

Benefits of Aquaponics Basil farming
