Product Description
※A hydroponic growing system typically contains three water tanks: clean fresh water,nutrient enriched and pH controlled water, and wastewater.
※The nutrient enriched and pH controlled water comprises the growth medium for the plants. The pH level and nutrient composition in this water reservoir is controlled using valves and pumps to add nutrients, carbon dioxide, or fresh water. Draining wastewater from the nutrient enriched water reservoir helps to maintain consistent water levels, while adjusting nutrient concentration and pH.
☆ High nutrient concentration > high conductivity reading > add fresh water
☆ Low nutrient concentration > low conductivity reading > add nutrients
☆ Overly alkaline solution > high pH reading > add carbon dioxide
☆ Low nutrient concentration > low conductivity reading > add nutrients
☆ Overly alkaline solution > high pH reading > add carbon dioxide
