pH controls is very important for stimulating full of life plant growth. The pH scale measures acidity or alkalinity on a scale of 0-14. Below 7.0 the pH is acidic. Above 7.0 , the pH is alkaline. 7.0 is nuetral. The most efficient pH for general plant growth is within the range of 5.5 to 6.5, somewhat acidic.Nutrient solution that may be too high (basic) or too low (acidic) can’t be properly asbsorbed by plants. Flawed nutrient solution pH can cause slow growth,sickly plants and low yields.
Designed to work superbly in hydroponic environments, both soil-less mixtures and soil grown plants
Includes pH Test Indicator tube:fill a test-tube halfway with nutrient, add a couple of drops of pH Test Indicator, and observe the coloration of the liquid within the vial.
For best results, discard and replace hydroponic solution often
