Why EC Monitoring Matters in Cannabis

Maintaining proper EC levels ensures your plants are receiving just the right amount of nutrients—not too much, not too little. High EC can burn roots, while low EC can starve your plants. The E50 Pro helps you keep nutrient levels dialed in throughout every stage of growth, from seedlings to flower.
