Know before you buy
No, this formula is not water-soluble. Because it is derived from natural, mineral-based ingredients like oyster shell and dolomite lime, you should shake the container thoroughly before each use to ensure the nutrients are properly suspended in the liquid.
Yes, CaMg+ is formulated to support both flowering plants and vegetables. It is particularly effective for crops that require extra calcium and magnesium to support fruit development and overall plant structure.
By providing a concentrated source of calcium and magnesium, this supplement optimizes plant metabolism and enhances nutrient transport. This leads to more vigorous growth and helps ensure your plants produce healthier, more robust flowers and fruits.
While the formula uses natural, organic-based ingredients like plant extracts and minerals, the product itself is not officially certified organic. It is designed for growers who prioritize natural inputs in their gardening routine.
You can use this supplement throughout the entire growth cycle to maintain plant health. It is especially beneficial during periods of rapid growth or when your plants are actively developing flowers and fruits, as these stages have higher nutrient demands.
