Take your hydroponic growing to the next level! Learn to optimize pH, EC, and nutrient solutions for maximum yield and healthier plants.
Back to guidespH controls how well plants can absorb nutrients. The ideal value is between 5.5-6.5 for most plants.
Too high pH: Add pH-down (acid) drop by drop. Test and wait 15 minutes between adjustments.
Too low pH: Add pH-up (base) carefully. Less is more – never overcorrect.
Tip: In Sweden, we often have hard tap water (high pH). Let the water stand for a day before measuring pH.
EC shows the concentration of nutrients in the water. Too high = nutrient burn. Too low = nutrient deficiency.
1.2 - 2.0 mS/cm
2.0 - 3.5 mS/cm
💡 Pro tip: Monitor EC daily. If the value drops quickly, plants are eating a lot and growing well. If it rises, they consume more water than nutrients – dilute the solution.
Keep water between 18-22°C. Warmer water contains less oxygen and increases the risk of root rot.
💡 Use an aquarium fan or cool the nutrient solution on hot days
Healthy roots need oxygen! Use air pumps with air stones to keep the water well oxygenated.
💡 Larger bubbles = more noise. Smaller bubbles = better oxygenation
LED lights provide the most light per watt. Leafy greens need 12-16 hours of light/day, fruiting plants 14-18 hours.
💡 Use a timer for consistent light cycles
Good water circulation distributes nutrients evenly and prevents "dead zones" where nutrients stand still.
💡 Check that all roots get access to the water
