Monkey Mag Cal supplies plants with readily available calcium and magnesium, two essential nutrients required for robust structural growth, chlorophyll production and efficient photosynthesis. Calcium supports cell wall formation and root development, while magnesium is vital for chlorophyll synthesis, ensuring your plants can produce energy effectively.
This supplement is especially useful in soft water areas or when using reverse osmosis (RO) water, where natural calcium and magnesium levels may be insufficient. Easy to mix and integrate with base nutrient programs, Monkey Mag Cal ensures consistent plant performance throughout all growth stages.
