FloraMicro is used during a plant's growth and bloom cycles.

First formulated in 1976, Flora Series is the original three-part hydroponic-based nutrient system (FloraGro, FloraMicro & FloraBloom). And thanks to its ingredients, consistent performance and unparalleled results, it's the most-used nutrient today. By adjusting the amounts of each part, Flora Series can provide optimally for a plant according to the stage of growth they are at.
