What Sensi Cal-Mag Xtra Does

Calcium helps to strengthen the cell walls of plants and increase the flow of nutrients throughout the plant. This will ensure nutrients reach your plants efficiently, increasing effectiveness, and ensuring that they are as healthy as possible. These actions together result in an increase in plant strength, enabling them to better cope with stress situations. Additionally, they will have thicker branches and more robust stems.

Magnesium is part of the chemical composition of chlorophyll. This compound gives plants their green color. Magnesium is also a key component in photosynthesis. It captures the sunlight's light energy and uses it to make plant sugars.

Sensi Cal-Mag provides 20 L-form amino acids. The essential building blocks for proteins and all other life, amino acids are vital. There are many roles that these amino acids play in life. Here's a list of just a few:

L-tryptophan is a growth hormone that helps increase the production of indole Acetic Acid, which can lead to larger flowers and greater potency.

L-Cysteine increases glutathione levels, which is a natural antioxidant essential for plants and humans. It helps to cope with environmental stressors.
