Know before you buy
General Hydroponics pH Up uses a concentrated blend of potassium hydroxide and potassium carbonate. These mineral-based ingredients work to neutralize acidity, effectively raising the pH to your target range.
Yes, this formula is versatile enough for both hydroponic reservoirs and soil drench applications. It is designed to help plants achieve optimal nutrient uptake regardless of the growing medium.
Because this is a highly concentrated liquid, you should add it in very small increments. Always test your pH level after each addition and stir thoroughly to ensure an accurate reading before adding more.
Since this product is potassium-based, it adds a small amount of potassium to your solution. While this is generally beneficial for plant health, you should always monitor your overall nutrient levels if you are making frequent or large adjustments.
Store the container in a cool, dry place away from direct sunlight and out of reach of children. Ensure the cap is tightly sealed after every use to prevent evaporation or contamination.
