Green House - Calcium is provided as an additive in situations where the amount of calcium present in the water is below the recommended levels such as Reverse Osmosis water.
Mixing Recommendations:
When added to water make sure to start mixing immediately.
RO, Rain water or any water with an EC of 0.0:
Because these kinds of water dont have the necessary amount of either Calcium or Magnesium, it is necessary to use Calcium additive when using any Powder Feeding products.
For your convenience Magnesium is included in all other Powder Feeding products. Also remember that most tap water already has enough Calcium.
Calcium Proportions:
These doses are for customers that are using RO water or rain water with an EC of 0.0. If you are using tap water, you need to test the hardness with Green House strips as the required doses will be lower.
