Our liquid Calcium is formulated with naturally occurring amino acids, allowing better uptake of calcium and improved transportation throughout the plant. Calcium is available over a wide pH range and helps prevent deficiencies during times of rapid growth and environmental stress.

Calcium is an essential element for all stages of plant growth. It is a fundamental building block of plant structures, helping in the activation of enzymes and necessary for cell division. Calcium is a relatively immobile element within plant tissue. This formula contains calcium complexed with amino acids, helping to draw calcium into the plant and improve the transport of calcium, which ensures an adequate supply to the growing tips and blooms.
