For optimum performance of your hydroponic system it is recommended that growers For optimum performance of your hydroponic system it is recommended that growers keep a pH of between 5.0 and 6.2. All plants grow well in hydroponic solutions within this range. The addition of dilute Potassium Hydroxide to your nutrient mixing tank will raise your pH to an acceptable level. We recommend the use of an electronic pH meter or pH test tape to measure the pH level in your mixing tank as the solution is added and stirred thoroughly.
For this pH Raise Solution we recommend that a grower fills a small jug of water first and then adds a small part of this solution to the jug of water so it is more dilute. The solution from the jug should then be gradually added to the mixing tank and repeatedly tested with a pH Meter until the correct pH level is reached.
