Nutrient Monitoring and Control
The monitoring and control of nutrient solutions is critical to successful propagation and optimization of plant growth. Different plant species have an optimal pH for nutrient uptake and growth. For those that have source water with a high alkalinity resulting in an elevated pH will add acid to adjust the pH to the right level. This process can be automated with a dosing pump to maintain the ideal pH for the plant. Just as with pH every plant has an optimal fertilizer concentration for maximizing plant growth. It is essential to monitor the concentration whether by conductivity (EC) or Total Dissolve Solids (TDS). As freshwater is added to a reservoir tank the fertilizer will decrease in concentration and should be corrected. This process can be done manually by hand or automated with a dosing pump to maintain the ideal EC/TDS for the plant.
