Green Planet Pro-Cal is the ideal solution to mineral imbalances in your growing medium, a simple application of 5 to 7ml per gallon is sufficient to make up for nearly any deficiency! Green Planet Pro-Cal is suitable for use with any growing medium, soil or hydroponic.
Please note: In hydroponic systems the iron may fall out of the solution relatively quickly due to the use of magnetic pumps without grounding probes and high levels of dissolved oxygen from air stones.
