Basil

Summary

As a high value and high demand product, basil is an extremely popular cash crop in aquaponics. It is often thought of as an ideal crop in aquaponics, due to its high uptake of nitrogen.

Growing

Basil grows ideally within the range of 20-25°C,although it can live within the wider range of 18-30°C. Particularly, under warmer conditions,such as 27°C and above, additional shade will be necessary in order to prevent tip burn among your basil crops; such shade should be around a twenty percent reduction and increased ventilation would be ideal.

Transplantion of seedlings should occur after the basil seedlings have matured to have 4 true leaves or more. Ventilation and a stable water temperatures of 21-25°C day and night aids in reduction of many commonly incurred diseases such as gray mold, Fusarium wilt, and black spot. During plant growth, the removal of flowering tips may reduce long term bitterness.

Harvesting

Once the basil has reached about 15cm in height, it is a good time to begin the harvesting process which can last another 4-7 weeks. Be mindful when removing and handling leaves to avoid bruising and blackening.

Nutrient Availability

The availability of macro and micro nutrients varies depending on the pH of your system. The chart below displays the pH range and the nutrients that would be available within an Aquaponics system. The Aquaponics system pH range is also indicated below in blue.
