How Do You Grow Basil In Aquaponics?

Some basil seeds are disease resistant and yield higher. You can plant aquaponic basil in two ways: germinating green basil seeds or clipping a node of another basil plant. Place the cut or pruned basil plant in a glass of water or aquaponics pot for a week or two where there is sunlight so it can grow.

  • Green basil is a plant that works well in warm weather, so your system needs to maintain a 70 to 80 degrees F temperature after sowing your seeds; water the trays at least two times a day.
  • Keep your seedlings from direct sunlight until they germinate. You can also cover the seedling tray with a polythene cover, and the seeds will sprout out in a few days.
  • Once small leaves sprout out, place them in partial sunlight and moisten the seedlings with a 10% nutrient solution or plain water at least two times a day. It would be best to be careful not to overwater the seeds when they are still germinating as they may rot. Keep watering the plants in the tray until their roots reach the bottom of the cube for about three weeks, then transplant them into your system.
  • Transplant the plants with a 10 to 12 inches spacing between plants to avoid nutrient competition and make room for higher yields.
  • Once you transplant them into your system, provide 6 to 8 hours o sunlight daily.
  • Every variety of basil in your system has a separate Nutrient composition suitable for the plant to yield aptly.
  • Basil plants grow 18 to 24 inches taller and produce many offshoots that can be harvested per plant.
  •  A young basil plant less than 10 inches has buds on the stems that haven’t grown yet. You can clip the stem above the buds to trigger them to grow out. This pruning helps the plant be more productive and maintain a good shape.
  • The best time to harvest your green basil leaves is before they bolt to flower.
  • Avoid pinching the leaves; instead, use sharp shears. After harvesting, store the harvested basil in plastic at temperatures between 52-58 degrees F.
  • When stored properly, green basil leaves can remain in an airtight container for 22 weeks while still fresh.
