At EVERGREEN, we’re revolutionizing modern cultivation practices with automated fertigation systems designed to maximize plant health, yield, and efficiency—while promoting ecological conservation and climate resilience. Whether you're managing a commercial greenhouse or scaling up a hydroponics setup, understanding and regulating key parameters like pH, EC (Electrical Conductivity), dissolved oxygen, humidity, and temperature is essential for thriving crops.
? Why Automation in Fertigation Matters
Unlike soil-based agriculture, soilless culture such as hydroponics lacks natural buffering. This means every aspect of the plant's environment must be precisely controlled. With EVERGREEN’s fertigation automation systems, you gain full command over:
Nutrient delivery
pH balance
Water quality
Environmental conditions
These smart systems ensure consistency, reduce manual labor, and enhance crop success.
⚡ Electrical Conductivity (EC): The Ionic Balance
Electrical Conductivity (EC) measures the concentration of dissolved mineral salts—the lifeline of plant nutrition.
High EC? It means too many salts—risking nutrient toxicity and root dehydration.
Low EC? The plants aren't getting enough nutrients, leading to deficiency symptoms.
✅ Optimal EC ranges from 2.0 to 3.5 mS/cm for most crops.
✅ Salt-sensitive plants prefer 1.0 to 2.6 mS/cm, while heavy feeders thrive at 2.6 to 4.6 mS/cm.
With EVERGREEN's Bluelab Guardian Monitors and peristaltic pumps, adjusting and automating EC levels has never been easier.
? pH: Unlocking Nutrient Availability
pH affects how well plants absorb nutrients from the solution. A suboptimal pH leads to locked-out nutrients or toxicity.
✅ The right pH varies per plant species but generally falls between 5.5 to 6.5 in hydroponics.
✅ Keep solutions within this range using our Bluelab pH controllers for real-time adjustments.
?️ Temperature: Root Zone Balance
Temperature affects nutrient solubility, oxygen availability, and metabolic activity.
✅ Maintain nutrient solution temperature between 15°C to 30°C (59°F to 86°F).
❗ Avoid sudden temperature shifts, which can stress plant roots.
EVERGREEN offers temperature-controlled reservoirs and monitoring systems to maintain ideal growing conditions.
? Dissolved Oxygen: Breathing Life into Roots
Dissolved oxygen (DO) is crucial for aerobic respiration, enabling efficient nutrient uptake and root development.
✅ Aim for 6 to 10 ppm or 5 to 8 mg/L in your nutrient solution.
✅ High temperatures reduce DO—so invest in cooling and aeration tools.
? Humidity & VPD: Managing Plant Transpiration
Humidity and Vapour Pressure Deficit (VPD) directly affect transpiration and nutrient transport.
✅ Ideal humidity levels are between 50% to 70%, varying by crop and growth stage.
✅ High humidity encourages disease, low humidity causes water stress.
EVERGREEN supports climate monitoring solutions to fine-tune your environment and prevent plant stress.
