Quick Start Guide
Why Measure EC or PPM in Hydroponics and Plant Nutrition?
Plants can only thrive when they get the right amount of food — not too little, not too much. EC (Electrical Conductivity) and PPM (Parts Per Million) readings help you determine how strong your nutrient solution is, ensuring your plants get optimal feeding for maximum growth and yield.
Too low EC = Nutrient deficiency, poor growth
Too high EC = Risk of nutrient burn and lockout
Perfect EC = Strong, healthy plants that grow faster and produce more
Whether you’re growing with coco coir, hydroponics, DWC, NFT, aquaponics, or soil, the Bluelab Truncheon is your go-to tool for consistent, reliable nutrient monitoring.
