Expand your toolkit to cover all the fundamentals

As a grower, your solution’s pH (potential Hydrogen) is the most critical fundamental measurement to track. It plays a crucial role in making nutrients soluble in water so that they can be accessed by your plants.

By measuring conductivity, temperature and pH, you’ll not only be actively managing your nutrient levels but also making sure that your plants have access to the food they need. This will lead to healthier, thriving plants and improved crop yield. Start tracking the fundamentals today.
