pH 4.01/&7.01 Calibration Solution 8 oz

​General Hydroponics uses the highest quality electronic meter reference solutions. Growers can use our reference solutions widely among many popular brands of meters using the NaCl scale. General Hydroponics technicians check each batch to ensure that our solutions are exactly calibrated each time they are used






1500 PPM@25C Calibration Solution, 25 x 20mL, case of 25

Hanna Instruments' calibration solution, ideal for gardening, laboratory work, and field experiments, comes in a package designed to keep air and light from damaging the solution.






SureTest™ pH Test Strip Kit

​The SureTest™ Kit includes everything you need to test the pH of your water or nutrient solution. Includes 15 ft of pH dependent color changing paper. The testers have a pH range from 5.5 to 8.0 in either 0.2 or 0.3 increments. Full color chart to match your pH test results.





pH Up gal Base

To maximize plant growth, the pH content 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 pH unstable media—such as rockwool and gravel products—are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.

pH Up: Base formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level.







pH Down 1 gal Acid

To maximize plant growth, the pH content 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 pH unstable media—such as rockwool and gravel products—are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.

pH Down: Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.
