If you’re growing your indoor plants in a hydroponic setup, it’s critical to invest in pH and TDS meters; it improves yield.
pH meters are for measuring the acidic or basic profiles of the water whereas TDS meters are for measuring the total dissolved solids in the water.
When you can determine the basicity or acidity of the water and the dissolved solids, it becomes much easier to give your plants optimal nutrient levels, thus achieving greater crop yield.
With the pH and TDS meters, it makes it easy to avoid using imbalanced water, which can have a negative impact on the plant’s capacity to absorb nutrients.
The following are the 10 best pH and TDS meters:
