FloraMicro contains submicronutrients and organic buffers that stabilize the pH. It complements FloraGro and FloraBloom in major and secondary nutrients. The Flora Series consists of three components: FloraGro, FloraBloom and FloraMicro. These were developed by Dr. Cal Herrmann and scientists from the University of Davis. FloraMicro Soft Water is suitable for water with a low calcium content. The success lies in the combination of all three components.
