We received this lovely photo from our client in KwaZulu Natal, the crops are grown in an area where water temperature can fall to zero degrees at night. The effects of the cold, will stifle the growth of your hydroponic plants as the optimum water temperature should be between 18-26C. Outside of these parameters the plants will not uptake the nutrients and they wont grow. It would appear if they are frozen in time. Our client uses a submersable heater in his watertank to keep the temeratures even in order to produce this luscious crop.
