pH is a measurement of the acidity or alkalinity of your water or nutrient solution on a scale of 0-14.

The level of your pH is an essential factor in deciding which nutrients are available for your plants to uptake, as certain nutrients will be easier to uptake at certain pH levels. Maintaining a stable and safe level of pH between 5.8-6.4 ensures that essential elements are available and can be absorbed by the plant.

A grower may have to adjust the pH levels of their solution for a number of reasons, such as the source of water being used or nutrients added.

Plants growing outside of the optimal pH range will see slower growth and nutrient deficiencies.

Our premium concentrated pH Down offers a clean formula for growers needing to safely lower the pH levels in their garden.

Green Planet pH Down is our highly concentrated premium acid formula made to help maintain and lower the pH of a nutrient solution.

Adjusting the pH to the optimal levels ensures your plants uptake the essential nutrients needed for all stages of growth.
