How pH And TDS Levels Affect Plant Water

May 04 2020 ph TDS water

Many of the water quality problems that gardeners face stem directly from what comes from the tap. Local municipalities need to provide water safe enough for human consumption. In general, humans are not adversely affected by water that has a high pH, but plants often are.Similarly, high levels of salts in tap water can certainly be a problem for both human and plant life, but it is expensive to remove these minerals. Two aspects of the water supply—pH and total dissolved solids (TDS)—affect many aspects of plant growth and vigor.TDS measures various salts that have been dissolved in water. These...

So what is pH... and why is measuring it so important?

Nov 04 2019 nutrients ph

pH is the measurement of acidity and its opposite, alkalinity in a solution. Neutral pH is 7.0 pH. Acidity measures below seven pH (7.0pH) with alkalinity measuring above it (7.0pH). It is important to maintain a hydroponic nutrient solution at a pH level where the elements in the nutrient solution are consistently available to the plant. If the solution is too acidic or too alkaline it can cause “lock up” – a situation which restricts certain elements essential for growth from being absorbed by the root structure. This is where things start to go wrong. Deficiencies in the required elements...
