Bluelab offers convenience and performance value in a portable pen design. The waterproof testing instrument provides speedy determination of crucial values that impact the growth and development of plants.
Successful management of plants and crops includes monitoring the level of nutrients that are being provided. It is also important to ensure that the plant roots are able to absorb the nutrients in an efficient manner. If conductivity levels are not within a normal range the nutrients are going to become inaccessible. The Bluelab ppm Pen helps you maintain the optimal EC and PPM values that the healthiest plants demand.
