Plants in any hydroponic system can only uptake nutrients within the range of 5.5 – 6 pH. If pH levels fluctuate outside of this range, certain nutrients will be locked out, leading to signs of a nutrient deficiency even if there is a high EC; with plenty of nutrients in the solution.
Proper management of pH is essential for optimal results.
Growth Technology has a full range of control solutions, essential for the proper management of nutrients in hydroponic systems. These products are manufactured using the purest and most concentrated sources available.
pH UP contains potassium hydroxide (KOH). This is a very caustic liquid and should be handled with extreme care. This product, at 25%, is stronger than some competing products. Always check the label for best value.
How to Use
A pH meter is essential for maintaining constant pH levels. To ensure healthy growth, pH should be checked at regular intervals and when changing the reservoir.
If pH levels are too low, pH up should be added. If pH is too high, pH down should be added.
When managing pH, only a small dose should be added at a time, stir the reservoir and then test the pH again. If more amendments are required, a small amount should be added each time due to the strength of the solution.
