We’ve been searching long and hard for a calcium25 replacement. The wait is finally over! Grow-Cal is derived from non-synthetic calcium chloride and is amino acid chelated with no EDTA chelators used at all, meaning this is safe for microbes. We believe multiple sources of calcium create the best results when considering immediate and long term needs. Grow-Cal can be used not only as a foliar but also as a drench and we’ve seen great results doing both.
Due to the chelation, when used as a drench, Grow-Cal may also help with the availability of other forms of calcium. Calcium carbonate is one of the most abundant sources of calcium but it does take time to become bioavailable. Grow-Cal may increase the rate at which calcium carbonate and other forms, become plant available.
