Calcium is traditionally one of the hardest things to make immediately available to your plants. Calcium can be delivered more effectively when coupled with nitrogen. Unlike Calcium Nitrate (one of the most antagonistic fertilizers in a biology-based system), Cal[NO]Mag is not ammonium nitrate based nitrogen, it is Amino Acid based nitrogen! This product is FAST in every way; solubility and uptake.

Containing 14%+ water-soluble plant-based Calcium. Since it's not calcium-nitrate or calcium-based lime, it is the most unique soluble-calcium solution on the market. Since it is separated from the magnesium, you can apply as much calcium as you need without adding additional unnecessary nutrients.

This product does not show a tentency to product negative reactions with any product currently available for agricultural pruposes

We recommend a 1-2 hr REI before re-entering the room, especially in a sealed indoor environment. In an outdoor environment, once the product has settled on the leaf surface and the water portion has evaporated/dried, you are safe to be near the plants without PPE.

We do not recommend you spray the product with pets/animals in the room. Also, the product should be kept safe from animals who may inhale/consume the product directly.

Yes. Since due to the nature of this product and how it is derived/formulated, it is highly compatible with microbial/compost teas

Although Magnesium is an essential nutrient, we removed it from this product (and placed it in our Green9 micronutrient product instead) to give growers the flexibility to add JUST calcium to their nutrient program. Oftentimes, Calcium is what you actually want/need and the Magnesium in traditional Cal-Mag products is redundant.
