Add CalCarb to your indoor and outdoor gardening arsenal and create the perfect environment for your plants. CalCarb is a readily available source of calcium and carbon dioxide. Calcium is critical to the health of your plant, contributing to the strength of cell membranes and regulation of nutrient use. It can also reduce the effects of heat stress in plants, while boosting growth and blooming.

CalCarb - Natural plant performance enhancement boosts photosynthesis both calcium and carbon are critical to plant development. Calcium is generally supplied through the soil and carbon enters the plant as carbon dioxide which is necessary for photosynthesis to occur. CalCarb is a unique form of a simple and very common compound that contains both calcium and carbon. Calcium carbonate or CaCO3 is used in agriculture throughout most of the world to adjust soil pH levels. But CalCarb is an unusual form of calcium carbonate that is highly unstable, converting to calcium oxide (CaO) and carbon dioxide (CO2) rapidly when applied to the foliage.

This unique phenomenon increases calcium availability to plants through the foliage, but more importantly, the CO2 levels directly outside and inside the stomata can rise threefold which is near the optimum for photosynthesis efficiency.

Forget to water? Didn't remember to bring that tender houseplant in before the first cold snap? If it is not too far gone, treat it with CalCarb and you may be able to rescue it. CalCarb helps in recovery by increasing photosynthesis in the foliage that is not too seriously damaged and by raising the surface pH of damaged foliage which deters airborne pathogens form taking advantage of the weakened cellular tissue. May Prevent Tomato End-Rot and Powdery Mildew.
