Description
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 Up™ pH Adjusting Solution This Base solution is formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time when your nutrient pH is too low in order to raise the pH to the proper level. Our dry pH formulation is particularly convenient for shipping. |

pH Down™ pH Adjusting Solution The Acid formulation uses food grade Phosphoric acid to lower the pH to the proper level. Our dry pH formulation is particularly convenient for shipping. |

pH Test Indicator Solution Tester General Hydroponics pH Test Kits make pH testing easy. Simply fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because of its reliability and ease of use, which are important factors when the health of a valuable crop is at stake. Use 3 drops per 5mL of solution. |

Standard Referece Solutions Meter Calibration Solution General Hydroponics uses the highest quality reference solutions, allowing growers to calibrate many popular brands of PH, EC and TDS meters (NaCl scale or the 442 scale). General Hydroponics technicians check each batch to ensure that our solutions are precisely calibrated and yield reliable readings each time they are used. |
