Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range. To help your plants thrive, get the fundamentals right by measuring pH and temperature to ensure that these are always in the optimal range.
