Hydroponics meters are key to ensuring an optimal growing environment is maintained for soilless growing. In typical soil gardening, plants usually get a vast majority of their nutrients from water and soil. However, in a hydroponic garden, plants receive a majority of their nutrients from the nutrient solution. Managing the nutrient content of the solution is very important, as the plant may die if the hydroponic solution is too strong or too weak. Measuring pH levels, temperature, electrical conductivity (EC), total dissolved solids (TDS) provides the grower important information for the maximizing the absorption of nutrients and minerals when using hydroponic growing systems. Using testing meters with the latest technology and the most accurate calibration that are built to last are essential for growing hydroponically. We offer a collection of the best hydroponics meters on the market today.
