PH 4.0 Calibration Solution 8oz.
This is PH 4.0 calibration Solution 8oz
pH refers to the acid content of the nutrient solution.
For plants to be able to grow best it is important that the nutrient pH be slightly acidic - the range of 5.5 to 6.5 is considered ideal for most crops.
Generally pH will be fine and won't require adjustment when our nutrient products are used since our formulas are "pH buffered".
