Water pH is a mathematical term to denote degrees of acidity or alkalinity and is expressed by a series of positive numbers between 0 and 14 with 7 being neutral. Zero being very acidic and 14 highly alkaline. Water pH can be measured by a hand held pH meter operated by a small battery. The [...]

Adjusting ph of the water supply is crucial for maximum nutrient availability.  It is seldom that the water supply, even from a well, is perfectly suitable (pH 5.8-6.8). The pH always needs some adjustment, either up or down. How to decrease the pH of a nutrient solution Lowering the pH is the most [...]

What is pH pH is the measurement of acidity or alkalinity of a solution. It is based on a logarithmic scale and starts at 0 and ends at 14 where the value 7 indicates a neutral, neither acid or alkaline. If a solution has a pH value below 7 it is called an acid. If [...]

Many growers are under the impression that a maintaining a specific pH is essential to optimal growth and good yields. This is a misconception about the effect of pH on plant growth. The specific pH of the nutrient solution does not have a significant effect on plant growth or for that matter the roots or [...]
