Organic nutrient use in hydroponic solution increases the sustainability of these systems by using waste. These solutions can be adequately reused if real-time nutrient concentration calculation is made with the use of electrodes. With the use of Ion Specific Electrodes (ISE), the relative absence or presence of an element can be calculated in real time. Theoretically, the use of these organic nutrient solutions could prove to be superior than inorganic solution for yield because of the microbiome.

Cannafish is a Startup working with hydroponic farmers to include manure and compost in their fertilisation plan. Doing so, they reduce the use of chemical fertilizer in hydroponics while valorizing organic residual matter. However, to replace chemical with organic fertilizers requires good practice and precision to achieve competitive yield. Hence, using a specific ion monitoring strategy in organic hydroponics can allow the preparation of a nutrient solution that is rich in nutrients and optimal for hydroponic plant growth.
