I transplanted plants into RDWC, and increase EC of the solution up to 500 ppm. Cutting was good for plants. I added Diamond Nectar into the solution. Note! Only one pump runs the solution in the system, temperature fluctuation within a day during the whole cycle – 16 – 21 C, and it is a good bonus for the plants in a cold time period. At the end of the week I turned the lighting to 12/12.
