Why use LOW CHLORINE NITROBLUE?

Many plants including vegetables and fruit are chloride sensitive, leading to reduced crop yields and growth performance. 
Excess Chloride may lead to a reduction of organic acids resulting in a flat tasting crop. Excess Chloride is detrimental to all crops under glass including seedlings and cuttings.
