pH Adjusting Solutions
Product 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.
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. Standard Reference Solutions are available in the following quantities: • 8 oz - 3 bottles included $14.95 | pH Adjusting Solution The Acid formulation uses food grade Phosphoric acid to lower the pH to the proper level. pH Down Dry is available in the following quantities: • 1.5lb • 4lb • 16lb $9.95 |

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. pH Test Indicator is available in the following quantities: • 8 oz $7.95 | • Feature push-button calibration and high ±1% full scale accuracy!
• Waterproof, dust proof housing that floats is certifiable to IP67 standards
• Replaceable sensor lets you reuse same meter body, saving you money
• Automatic Temperature Compensation
• 0 - 1990 PPM
• Hold function, Auto-Off
