EC CF PPM NUTRIENT METER SWRS-100A

It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing.

If the conductivity reading is too low, your plants may not be getting enough nutrients. If the conductivity reading is too high, plants can dehydrate. Understanding the conductivity of the nutrient solution takes the guesswork out of feeding plants. It will also save you money!
