This product is a phosphoric acid compound that lowers your nutrient solution’s pH to a proper pH range. Experienced growers consider the ideal pH for most crops to fall between a 5.5 and 6.5 range, which gives the substrate slightly acid nutrients that maximize plant growth by providing a propper ambient for maximum absorption of nutrients. pH Down Plus won’t cloud the water of your pool or spa, like lime or soda ash.
pH Down Plus reduces the pH to the proper range required for plants to grow. When pH is too extremely out of range, your plants may die! It also helps to neutralize excess alkalinity in your water systems (pool, spa, hydroponic irrigation, among others).
