pH Up and pH Down regulate the pH for optimal nutrient uptake and stable beneficial bacteria colonies, and they forestall nutrient deficiencies.
THINGS TO NOTE
Emerald Harvest professional base nutrients and supplements are pH buffered, so if you’re using our full product line as directed, your garden should already have a balanced pH.
When the pH of the nutrient solution is too low or too high, certain elements (e.g., iron or manganese) could be wholly or partially “locked out.”
The sweet spot, pH 5.8–6.3, is the ideal pH range for high-value plants grown in hydroponic gardens.
