Xtreme Gardening CalCarb Foliar Spray, 6oz

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.
