General Hydroponics pH Down
This concentrated solution from General Hydroponics is basic equipment for any hydroponic system. pH levels in water vary greatly from water source to water source. Different plants respond positively to different pH levels. Most plants need pH levels between 5.5 and 6.8. Add General Hydroponics pH Down to your nutrient solution to lower pH.
To maximize plant growth, the pH of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered.
However, some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or when pH unstable media – such as rock wool or gravel products – are used, or when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.
pH Down: This acid formulation uses food grade phosphoric acid to lower the pH to the proper level.
