CalCarb

CalCarb is a revolutionary calcium carbonate foliar spray proprietarily-derived from a naturally occurring compound. It utilizes a new form of nanotechnology which processes the compound to such a fine size that it is able to permeate the foliage of plants. Once inside the cell walls, CO2 is released as both calcium and usable carbon dioxide, increasing photosynthesis levels three-fold.

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.

Easily Applied to the Underside of Foliage!

Stress Reduction and Plant Rescue - 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 from taking advantage of the weakened cellular tissue.

May Prevent Tomato End-Rot and Powdery Mildew.

Great
Bought the 2 pack for myself and my daughter. Haven't heard back from my daughter, but I like the way it makes my skin feel plus the smell is great. I also like that it's homemade and all natural plus will help with psoriasis &/or eczema which my daughter has currently. I would recommend other to try and if I run out, I would buy more again.

Definitely works!
I noticed I was having weird rough patches on my back and thighs but didn't know what they were. So with my next appt to the dermatologist, I found out it was eczema. Ugh. So I started looking at creams and such and stumbled on this bar soap. It works really well. When I shower, I work it into the problem areas and let it sit there with the shower head turned away so it doesn't wash off, and then wash my face, etc. When I'm finished with everything, I wash everything off, after the soap has been on my skin for several minutes. I've noticed a substantial decrease in the bumpy areas on my back and legs. I loooove this soap, and yes, definitely recommend it for people dealing with eczema. But definitely use an exzema skin cream too if you are itching. I wasnt, but started to as well because it also helps to keep the outbreak under control as well.
