What The PH?!?

In chemistry, pH (potential of hydrogen) is a numeric scale used to specify the acidity or basicity level of an aqueous solution.

pH measurements are important in agronomy, medicine, biology, chemistry, agriculture, forestry, food science, environmental science, oceanography, civil engineering, chemical engineering, nutrition, water treatment and water purification, as well as many other applications.

The pH utilizez a numeric scale with numbers from 0 thru 14. Number 0 is very Acidic while number 14 is very Basic. Number 7 is considered neutral.

For optimal plant growth, the pH level of your nutrients should be adjusted to its appropriate level. Various plants like different pH levels. Most experienced growers consider the ideal pH for most plants to fall between 6.0 and 7.0. The pH value of the nutrient solution will determine the various elements available to the plant. Growth rates, water quality, and growing medium are just some of the major factors that can destabilize the pH in your nutrient tank and affecting the growth rate and development of your plants.

Microelements such as iron, maganese and zinc become less available as the pH is raised from 6.5 to 7.0 or 8.0. Molybdenum and phosphorus availablity in the opposite direction. pH values which are too high or too low will be detrimental for optimal plant growth.

pH can be easily measured thru the use of pH Test Strips, drops or an electronic pH meter.

Products like Green Cross Hydroponics PH UP & PH DOWN can easily and safely adjust the pH levels of your nutrient solution to ensure optimal plant growth.

Powder or Liquid Fertilizers : Which one is the better choice?

Powdered pre-mixed plant fertilizers are often a cheaper and easier way to grow  for the hobby horticulturist.

When using premixed powdered fertilizers, it is very difficult to achieve a homogeneous mixture of fertilizers when hundred of pounds  of individual compounds are mechanically mixed together and will not mix evenly due to the different size, weights and volumes of the individual components. Many of the compounds are in powder or fine grain form which often gets clumped together during shipping and storage. Experience with such powdered pre-mixes has often revealed shortages in magnesium and iron and excess of manganese.

This nutrient imbalance is why many commercial grows use pre-made or custom made liquid plant fertilizers in order to avoid any nutrient imbalances, deficiencies and toxicities.

Prior to dispensing any premixed liquid plant fertilizers, the container should always be slightly agitated to ensure an even distribution of nutrients in the liquid solution prior to use.
