Calcium is essential for plant health.
TrueNute Calcium Sulfate will not raise your PH, so if you have your PH where you want it, or you have a high PH, this is the calcium to add to your system water. Maintaining the correct calcium level can be tricky. Please purchase a calcium test kit to ensure you are maintaining the correct calcium levels as per the instructions included with your shipment. We have listed the test kit we use below.
