Swiss Chard


Chard is a popular choice in aquaponic systems due to its marketability, rapid growth and nutrient density.


Swiss chard can grow in temperatures as low as 5°C, although it thrives in the range of 16-24°C. If growing chard in warmer conditions, a shade is suggested.

Thinning ia required during the germination process, as seeds often produce more than one seedling.


Leaves can be harvested as the reach desired size, as the removal of larger leaves will encourage the gorwth of new ones.
